With a command area of 16 million ha, the Indus Basin Irrigation System is one of the largest contiguous irrigated systems in the world. The country's contribution to the science of irrigation has been of great importance. The present system encompasses the Indus river and its major tributaries, three major reservoirs, 19 barrages or headworks, 12 link canals, 46 canal commands, and over 107,000 water courses. The total length of canals is about 60,000 km (Siddiqi, 1994). It accounts for 26 % of the GDP, provides 80 % of the overall value of exports, and employs 54 % of the labour force (Siddiqi, 1994). In this system, the water is diverted from main canals to branch canals, then to distributaries and water courses. It was designed a century ago as a gravity flow, run-of-the-river system with an objective of extensive and equitable use of water: the water has to serve as large an area as possible, and to be distributed equitably to sustain as large a rural population as possible at low cost. It is a supply based system, i.e. the water allocation and distribution is essentially controlled by the supply at the head of the canal. Agricultural production for three major crops (wheat, rice and sugar cane) has been stagnant for the past 20 years whereas the population growth remains at a high rate of about 3 % (Kuper et ai, 1994). So with the world's "Population Explosion" and the demand for additional food, the science of irrigation is likely to become the science of survival. Vast areas earth in Pakistan are situated in arid zones and even those in humid zones may not have evenly distributed rainfall. It is only through the artificial application of water that large culturable tracks of land can be brought under cultivation. To irrigate our sweet and fertile land in the Punjab, the Punjab Irrigation & Power Department is responsible for the operation and maintenance of related works. In the land of five rivers, Punjab, there is a huge canals network irrigating perennially and non perennially in addition to a vast system of link canals with all related hydraulic works. The distribution and application of water to the lands requires adequate knowledge of the agricultural aspects of irrigation, i.e. the crops and their seasons, the types of soil with their characteristics and chemical composition, and the inter­ relation of crops, water and soil. Finally, it. is important to avoid waterlogging and salinity, and the consequent loss of cultivable land. But, unfortunately due to economical or other constraints, the system is deteriorating day by day and this worlds' important system faces much trouble for smooth and safe running. The careful research using modern methodologies, techniques and tools required for the 1 up keeping of system to cope with the battle of hunger and poverty on scientific grounds has not been given due importance and very many efforts have been made so for to improve the existing system. Due to this negligence and unrealistic approach, 70 to 80 per cent population of Pakistan depending upon canal irrigation are facing problems for their survival. Keeping in view the difficulties experienced by the Punjab Irrigation & Power Department (in various fields of irrigation), for the improvement of the existing system by using new and modern techniques and methodologies, IIMI (\nternationallrrigation Management Institute) has been asked for collaboration in various research activities. For this purpose, in Fordwah/Eastern Sadiqia area in Bahawalnagar circle (Irrigation unit in Punjab) IIMI has been involved in research activities for the last three years, and some results are now being tested in the field, to demonstrate the possibility of a productive collaboration work between researchers and managers. The main objective of IIMI's research in this area is to develop and pilot test in collaboration with national research and line agencies alternative irrigation management practices to optimize agricultural production and mitigate problems of salinity/sodicity. The research is found very helpful in aims to develop tools to assist irrigation managers to take better founded decisions on operations and maintenance. So on the special recommendation of worthy Chief Engineer Bahawalpur, the then Superintending Engineer Bahawalnagar, research on perennial system i.e. Malik Sub-Division canals started and is now under progress. Before discussion on the existing conditions of canals in Malik sub-division and on going activities, we will first discuss some history of irrigation at a glance. 1.2 WORLD HISTORY OF IRRIGATION The art of applying water to the land dates back to the beginning of human civilization. The oldest canal still in use was begun about 1900 b.c. in Egypt, by the Prophet Joseph when he was Grand Vizier to the Pharaoh. This canal is situated in Medinet-I-Faiyum, 80 miles south of Cairo and irrigates the lush green fruit gardens of that area. It leads off the Nile, is about 200 miles long, and is called Joseph's canal by the fellahin. The Holy Quran also throws some light on the great canal system , inherited by Ramses-ii (1304-1237 b.c.'. It is thought that the floating basket carrying the infant Moses may have reached the gardens of the Pharaoh's palace by way of a canal leading off the Nile. Egypt claims to have the world's oldest dam, 355 ft long and 40 ft high, built some 5000 year ago to store water for drinking and irrigation. It was built by king Menes (C.3100 b.c) across the Nile near Menesphis. The Holy Quran mentions the destruction of the flourishing community of Sabah in Yemen in the following verse: "but they turned away, wherefore We sent upon them the inundation of the dam and We exchanged their two gardens for two gardens bearing bitter fruit and tamarisk and some lote-trees". The dam mentioned in the 2 above is known as Sadde Marib (Marib dam) and was built 3 miles from the capital city of Marib, 60 miles east of Sanah in 800 b.c.(lqbal Ali, 1975) The indo-gangetic plain also boasts an ancient irrigation system. Archaeological excavations at Harappa, Moenjodaro and Kot Dijji have revealed the existence of an . advanced civilization based on some form of irrigation system. In the recorded history of the sub continent, the practice of the irrigation can be traced back to the 8th century when the Muslim invaders differentiated between irrigated and non irrigated lands for the purpose of levying land tax. The present elaborate system of the western Jamna canal is believed to have been based on a system initiated by Feroz Shah Tuglaq. Ali Mardan Khan, an Engineer and Governor of Punjab during Shah Jahan's rule, constructed the Hasli Canal leading off the Ravi which forms the nucleus of the present upper Bari Doab canal, (Iqbal Ali, 1975). 1.3 IRRIGATION IN PAKISTAN Pakistan's irrigation system has a great importance over the world globe and was extended enormously over the last hundred years. In the middle of the 19th century when the British took over the control of the sub continent, there were only a few inundation canals in the area now comprising Pakistan, irrigating some 200,000 acres. By the end of 19th century a number of separate inundation system had been developed for each river. The total irrigated area increased to 3.6 million acres, with a total canal mileage of 4340 miles. At the end of the 19th century efforts were also made to construct a weir control irrigation system. The inundation systems were merged with the various perennial irrigation schemes when these were completed and both are now being fed from the storage dams at Warsak on the river Kabul and Mangla on the river Jehlum as well as from the 17 barrages and headworks. Pakistan perennial irrigation system is the world's third largest, irrigating some 33 million acres with a total canal mileage of 40,000 mile and a discharge of 2,30,000 cusecs. In addition a vast system of link canals was constructed in the 1960's for transferring the water of the western rivers to the canal system which used to be fed by the eastern rivers, Beas, Sutlej and Ravi (Iqbal Ali, 1975). As our study relates to Malik Branch system, so we will focus on the history of that part of the system. 1.4 HISTORY OF IRRIGATION IN BAHAWALPUR STATE Bahawalpur state was bounded on the north and west first by the combined Sutlej and Beas Rivers, then by Chenab River :md finally by the Indus. The length from 3 the north-east to south-west was about 300 miles and its mean width was about 66 miles. The total area was about 20,000 square miles of which two thirds was under desert, and the rest was cultivated. The State abuts on the rivers, 170 miles border along Sutlej, 50 miles border along Chenab and 80 miles border along Indus. The climate was dry and hot for the greater part of the year. Rain was scarce. We\\ water was sweet in riverain tracts but brackish in the old "Cholistan" and now new colony areas. The main industry was agriculture. Prior to its connection with the British Power in India in 1833, Bahawalpur state was an independent sovereign State pawning allegiance to no supreme power. In 1833 the state entered into a treaty with the British Government in India whereby a Political Agent of the British Government was posted in Bahawalpur, the State remained completely independent in all internal matters and enjoyed full sovereign rights. The rivers passing through Bahawalpur territory were considered to be the property of the state and the Ruler levied tolls on merchandise transported on the Indus river. The British Government did not interfere in this right of the State. From the irrigation point of view, the State could be divided into three tracts each running parallel to the other. a) Drift Sand Area b) Riverain Tract c) Central Tract For more detail of irrigation see the note by Mr.Barns, Superintendent of Irrigation in the State, 1868 quoted in Pir Muhammad Ibrahim (1948). Bahawalpur State Canals: In connection with the canal irrigation in the state Mr.Barns says:­ "Irrigation must have always been in vogue and, equally with Sindh and the Punjab, the canals received more or less care as the ruler for the time being was energetic or otherwise. My opinion is that in a period less than 50 years ago the irrigation of this state was in a far more prosperous condition than when Major Minchin took over the charge of State; the number of canals large and small (omitting all under 10 feet breadth) then in existence was as follows:­ viz., 26 from the Sutlej, 6 from the Chenab and 6 from the Indus. " (Page 243 of the Punjab State Gazette, Volume XXXVI A Bahawalpur state 1904). The inundation canals to which Mr.Barns refers were constructed at different times. It will be interesting to note the dates of construction of a few of them with area irrigated, see Annexure-A. 1.5 SUTLEJ VALLEY PROJECT (JUNE 1920) This project provided for the construction of 3 weirs on the river Sutlej, below its junction with the river Beas; and a fourth weir on the Panjnad reach of the Chenab below its junction with the Sutlej. Three perennial and five non-perennial canals, and 4 two "combination" canal (perennial and non-perennial) with an approximate aggregate Kharif capacity of 48516 cusecs had been proposed to take off from the rivers at these weirs for the benefit of Punjab, Bahawalpur and Bikaner territory. This project was designed for the annual irrigation of 3.5 million acres over and above the 1.5 million acres already supplied by inundation irrigation, which latter area was also to benefit by the more reliable supplies resulting from the construction of weirs. It rendered available for colonization nearly a million acres of crown waste land in British territory and a further 2.5 million acres in Bahawalpur and Bikaner States. The cost of the entire project was estimated at nearly 24 crores rupees and the financial return therefrom on the British portion at 15 per cent, taking estimated credit for the sale of crown waste land. This project received the sanction of the Secretary of State for India in November, 1921. Before the construction of the weir-controlled irrigation system, the following inundation canals were present in the Sutlej Valley Project are: a) Lower Sutlej inundation canal system b) Hajiwah canal c) Upper Sutlej inundation canal system d) Grey canal of Ferozepore district e) Bahawalpur state inundation canal History of (a-d) is available but left untouched due to the focus of this report and can be provided on request. The Sutlej valley project provided for four weir on Sutlej, at Ferozepore, Sulemanki, Islam and on the Panjnad reach of the Chenab. Canals were constructed for supplying water both (perennially and non perennially) to tracks in the Punjab province and in Bikaner and Bahawalpur state, under a tripartite agreement by which the water available at those weirs was to distributed to the various canals. The Panjnad weir which was constructed below the confluence of the Sutlej and the Chenab allowed the Bahawalpur state to participate in supply in the Chenab as well as in the surplus water of the Sutlej for their canals taking off at the Punjnud weir (Pir Muhammad Ibrahim 1948). The detail information of all the canals taking off from the various weirs has been provided in Annexure-A. On the Sulemanki headworks, which lies in the west Punjab, two canals were proposed on the left bank, Fordwah canal and Sadiqia canal. Fordwah canal lying in Bahawalpur state was proposed for irrigation in state territory and replaced the Fordwah inundation canal. It was designed with a head maximum capacity of 3366 cusecs and a share capacity of 2244 cusecs to irrigate a gross area of 450934 acres and a culturable area of 434731 acres. The Sadiqia canal also lying in Bahawalpur state offtaking from left bank of Sulemanki weir is a perennial canal irrigating Bahawalpur state designed with a head capacity of 4917 cusecs to command a gross area of 1078640 acres of which 5 according to Sutlej valley project Bahawalpur inquiry committee report 840474 acres were culturable. It replaced a farmer state inundation canal of the same name and in addition took up a large area of state waste. The tail of canal was proposed at RD 245000 where it trifurcate into Hakra Branch, Malik Branch and Sirajwah Disty. Administrative information of Sadiqia Division is given in Annexure-B. Sadigia Division Sadiqia Division is a perennial unit of Sutlej Valley Project (1920) included in Bahawalnagar canal circle. It is headed by an Executive Engineer stationed at Bahawalnagar. He is assisted in technical, operation, maintenance and revenue matters by 3 canal and 1 drainage SDO with 14 Sub-Engineers. Additionally, 1 Deputy Collector with 10 Zilladars is also available for assistance in revenue matters. Sub divisional set up is given in Annexure-C. 6 CHAPTER: 2 DESCRIPTION OF THE STUDY AREA 2.1 MALIK SUBDIVISION Malik Sub Division is an important sub component of Sadiqia Canal Division. It has a vital and tremendous role in the agriculture, economic and social sector of the area under command. It totally falls in Bahawalnagar and Chishtian tehsils. It starts from the tail of Eastern Sadiqia Canal.The layout of the canals is given in Annexure-E. Details of Malik SUb-Division's Sections, Administrative and Communication set up are as under: a) Sections: Kot Sher Muhammad: Kot Sher Muhammad Section includes Malik Branch Rd 1000 to 95900, Gajjiani Disty (Rd 0 to 53200), Mahmooda, Bhukan, Dhaban and Thakt Mahal minors (head to tail). Data at head Malik and Gajjiani is collected 3 hourly and conveyed to Bahawalnagar twice a day where as data at head and tail of other channels are collected and conveyed daily under personal supervision of Sub Engineer incharge whose sanctioned headquarters are at Kot Sher Muhammad rest house. Signaller is also stationed at the same point. Gajjiani: Gajjiani section includes Gajjiani Disty (Rd 53200 to tail), Chak Abdullah, Kokni, Chatala, Chishtian Minors and Madrissa Sub Minor (head to tail). Data at head and tail are collected and conveyed to Bahawalnagar daily under personal supervision of Sub Engineer incharge with sanctioned headquarters at Gajjiani Rest house. Signaller headquarters is also at Gajjiani Rest house but data is conveyed through Chak Abdullah telegraphic station due to non working of Gajjiani Channina link. Sirajwah: Sirajwah section consists of Sirajwah Disty (Rd 1000. to 67700). Bahadurwah, 1/R Bahadurwah and Najibwah Minors head to tail. Data at head Sirajwah is collected 3 hourly and conveyed to Bahawalnagar twice a day where as data at head and tail of other channels are collected and conveyed once a day to Bahawalnagar under personal supervision of the 7 Sub Engineer with sanctioned headquarters at Donga Bonga Rest house. The Signaller also stationed at Donga Bonga. b) Administrative Set Up Total 1735 cusecs (1538 Malik, 197 Sirajwah) of authorized discharge is being delivered through four major, two minor and almost 50 direct outlets to Malik and Dahranwala Sub-Divisions. The Malik Sub-Division is headed by the Sub Divisional Officer stationed at Bahawalnagar. The three Sub Engineers and three Zilladars help the SDO in technical and revenue matters. Administrative set up of the sub division is given in Annexure-C. c) Communication Set Up As explained above Malik sub division has three sections: 1) Sirajwah 2) Kot Sher Muhammad and 3) Gajjiani sections. Communicational and sectional set up of the sub division is presented in Annexure-D. 2.2 MALIK BRANCH Malik Branch is the second largest offtake of Eastern Sadiqia Canal. It replaced a vast track of land in Bahawalnagar and Bahawalpur Districts being irrigated by inundation canals in the past. The command area is fertile, but some patches are badly water logged and salinity affected. Over all efficiency is good. The channel has a vital and tremendous role in increasing the agriculture, economic and social values of the area. The land holdings are small, but some larger farms are also present in the command. Most of the channel length is in filling and high seepage can be observed. Permanent Features Malik Branch was designed perennially for 1538 cusecs and offtakes from tail Eastern Sadiqia canal at RD 245000/R. The total length of the branch is 23.38 canal miles, out of which 4.2 mile falls in Dahranwala and 19.18 mile falls in Malik Sub division. Channel has 90 ft bed width and 6.5 ft full supply depth in the head reach and 75 ft bed width and 5.90 ft full supply depth in the tail reach. The water surface slope varies from 0.11 to 0.12 per 1000 ft in total run. The value of lacey's silt factor had been adopted as 0.80 with free board 2.5 ft. The discharge at the tail is 1042 cusecs. There are hydraulic control points combined with fall and bridges at Rd's 22900, 38900 and 95900 to maintain the water levels as per command requirements. Hydraulic structures at head and Rd 38900 are provided with mechanical gates to control regulation. The structures at RD 22900 and 95900 have not been provided with gates. A cross regulator has also been provided at Rd 86000 to feed lift 8 outlets in low supply periods. Detail of the total GCA/CCA, three year irrigation figures and major crops are provided in Annexure-F. Operational Issues Malik Branch has excellent working head while offtaking from parent channel. Gated structure with free orifice flow conditions are available at head. The discharge table is present but requires rechecking. The discharge at the head is most of the time higher than the design discharge, leading to scouring of bed and erosion of sides in most of the reaches. Some lift irrigation outlets also exist. Total supply is distributed among the irrigators through one major, two minor secondary canals and 45 direct outlets in Malik sub division. Most of the direct outlets are pipes, but some OCOFRB and OCAPM outlets also present. The left bank is 25 ft wide with a service road and the right bank is 15 ft wide. They are in good condition except some points where cattle cross regularly. Some reaches are without berm and free board resulting in a loss of capacity of reaches, giving a smaller security margin for operations. However over all outer and inner prism is in good shape and has a potential to sustain the thrust of excess except reaches between RD 23 to 37, RD 39 to 57 where the smallest margin of operation exists, as the right bank is in a bad shape. An abrupt drop in the elevation at RD 49 to 51 implies a risk of overtopping due to which the gauge reader at RD 38900 is very limited in his operations. The head regulators of Mahmooda and Bhukan disties are without gated structures, and normally, draw excess in full supply days which is why these distributaries have a better performance than bigger distributaries. The discharge tables at these points are missing, so it is very difficult to control excess supply and save valuable supply. This fact is very much clear from the irrigation figures of both the channels (see Annexure-F). Fall and bridge RD 22900 without gates works modular. Due to non-availability at Mahmooda & Bhukan distributaries and inconsistent gate movement of Gajjiani discharge variation in Malik Branch RD 38900 can be seen (see Graph-V). The cross-structure at Rd 38900, where Gajjiani Disty offtakes, is an important regulation point with gated structure. Supply/indent of Dharanwala sub-division is also met at this point. Discharge table is available but requires rechecking. Head and cross structures at this point are hydraulically weak. Even the right side pitching of Malik Branch in a length of almost 70 ft slipped down in previous closure 1994/95 and Department had to face a difficult situation. This work was repaired/completed on an emergency basis. Left side pitching also requires attention. At this point heavy fluctuation is the major operational problem and feeding of secondary canals (Fateh Murad) taking off from tail has become a burning issue. This situation is alarming and has an adverse effect on the efficiency of the system. See Annexure-I & F. 9 The official rotational schedule is strictly followed and implemented as it is approved by SE. However the targets or objectives of water distribution are not clear, as per modern techniques and requirements of crops, leading to problems in the fair distribution of water when demand is in full swing. For detail of last year and existing supply conditions see Annexure-F. A lot of responsibility is left to the gauge readers, especially in slack demand days. Some secondary canals are even fed when there is no demand and a valuable supply can be saved for use in other areas. In routine management, they perform a good local control. But this local control can not tackle the 'fluctuations that enter the system, as they are amplified by operations inside the Sub Division. This leads to a highly variable discharge in the Branch and ultimately transfer into secondary canals, resulting in bad situations at tails. Sometimes breaches occur, partly because of these reasons. As a result, the canal is almost never in steady state. At RD 86000, there were two high level offtaking channels Le. Khober and chandana. These were closed around 1975 and supplies delivered to the irrigators by direct outlets. Provision of cross regulator for feeding in low supply or other suitable suggestion instead of giving direct outlets by closing distribution canals in 1975, is a separate issue, which will be dealt with in a later stage of Malik Branch studies and adverse or favourable results will be discussed. Now for feeding of high level outlets, a cross-regulator has been constructed in 1991/92 at the same point. The cross-structure at RD 95900 works modular with sufficient working head. The indent of Daharanwala sub division is met at RD 38900 instead of this point. There is no discharge table available. To improve the working efficiency of canals in lower reach, indent must be fed at RD 95900 and proper data collection facilities must be provided there. In channel command, no proper drainage system exists. In most of the reach, N.S.L (Natural Surface level) is lower than the channel bed and high filling adds to intensive waterlogging due to a high seepage rate. Cutting reach is only in between RD 63 to 70. The process of data collection (explained under sectional distribution set up given in Annexure-D) and its analysis has not been optimized, and the evaluation process is almost not performed at all. With a precise study of data collection and analysis, adequate knowledge of modern techniques in operation, improvements in links between gauge readers, the performance of the system can be stabilized with a high efficiency rate, tempering the coming fluctuations in the system with present security margin. 10 MEHMOODA DISTY Mahmooda Disty is the first secondary canal of Malik Branch. It is a high level channel whose command area is intensively affected by waterlogging and salinity in the tail reach. Some well organized farms are included in the command with lush green orcards. Permanent Features Mahmooda Disty was designed as a perennial unit of Malik Branch for distribution of 15.5 cusecs of discharge. It offtakes from RD 15464/R of Malik Branch and has a total length of 2.68 canal miles. There is no mechanical gate provided at head which works modular. A discharge table is missing. The details of total GCA/CCA, total number of outlets. major crops and last three year irrigation figures are provided in Annexure-F. The channel was designed with 10.8 ft W.S.W. in head reach and 1/3333 bed slope. No control point available to maintain the water level in this channel. Operational Issues In full supply days of Malik Branch. this channel runs a discharge more than authorized, which has adverse effect on the fertile command. Valuable agricultural land is being wasted every year. Unfortunately. due to paucity of funds in the past. no re-sectioning work has been carried out since long. Heavy growth of Jungle/Sarkanda with silt dunes can be observed along the channel on right side. Banks are weak with no berm and free board. leading to lesser security margin in operations. The channel potential capacity can not be used. and implies a risk of overtopping. Topography is such that the left side area is comparatively high as compared to the right side. The official rotational schedule is followed strictly as it is approved, that is why channel has abnormal shortage at tails in low supply periods of parent branch. As data collection and analysis are not optimized, and the evaluation process is almost ignored, that is why it has a poor performance than the other offtakes. It is also difficult to meet the targets or objectives of equitable and fair distribution during the whole season and reducing the shortage. Situation in low supply periods of muddy water has reduced the capacity and risk of overtopping has increased. Hydraulic data is collected and conveyed through telegraphic station at Kot Sher Muhammad daily. Tail front works modular where as tail left works non modular. For more information· of hydraulic data,existing and last year supply conditions see Annexure-F & G and communication link, layout, administrative control has been provided in Annexure-B, D & E. 1 1 BHUKAN D\STY Bhukan Disty is the second offtake of Malik Branch. It is high level channel. Most part of the area under command is water logged. However, some good patches of land are also irrigated by this Disty. Overall performance is good. Permanent Features Bhukan Disty offtakes from RD 22500/L of Malik branch with authorized discharge of 13 cusecs and tail RD 17640. The details of total GCA/CCA, Major crops, number of outlets and last three year irrigation figures are provided in Annexure-F & H. Head Structure works modular but has no gate. The discharge table is also missing. There are 8 outlets designed as OFRB. Being a high level channel, shortage of supply is experienced in low flow days of Malik Branch. Designed velocity and bed slope adopted as 1.28 ft/sec. and 115000 respectively. Operational Issues As the head structure is without gate and regulation is being done by karries, so there is no permanent control and a lot of fluctuations ente the system which are very difficult to temper for equitable and fair distribution. As a result, the canal is almost never in steady state. The channel is also facing problems due to topography. Additional supplies are also distributed among the irrigators for reclamation purposes. Channel reach 0-7500 is in high filling. The bank position is weak, leading to loss of capacity in head reach with a smaller security margin for operation. There is no berm and free board available. Reach RD 7500-14000 passes through high level sandy dunes, when heavy wind storm carrying with dust blows in summer season, channel chokes up and the tail suffers. In the tail reach waterlogging patches are observed. There is no control point available on this channel to maintain water levels for better command, which effects modularity and efficiency. The official rotational schedule is strictly followed due to which targets of equitable distribution in low supply in Malik Branch are not achieved, and lot of variation in discharge at tails is observed. This is further aggravated due to non optimization of data collection and analysis and non performance of evaluation process. Supply conditions can be improved by provision of regulation gates at control point of Malik Branch RD 22900 just downstream of, the canal. Hydraulic data is collected and conveyed to Bahawalnagar daily through Kot Sher Muhammad. For detail of existing and last year supply see Annexure-F. Strengthening with side protection in reach RD 2200-3500 (right and left side) is recommended due to settlement of local Abaddi's in this reach. In the rainy season a number of mishaps are observed. Trespassing and cattle ghats must 12 be discouraged to increase channel efficiency. For more detail of hydraulic data see Annexure-G. Layout, communication link and administrative control has been provided at Annexure-B, D & E. Initially, channel tail was at R.D 23040 but on the request of share holders the tail was curtailed and some outlets were shifted to Malik Branch. L-Section and A-Form approved vide Superintending Engineer Bahawalnagar circle no 1135 dated 29-1-1994 has been implemented and now there is no maior tail shortage. 2.5 GAJJIANI DISTY Gajjiani Disty is one of the most important and major distributaries of Malik Branch in Malik Sub Division. It irrigates very fertile and lush green agricultural belt of land in Bahawalnagar and Chishtian tehsils. Number of well organized farms are being fed by this system and this Disty is playing a vital role in the agricultural sector of Bahawalnagar District. As a whole, the system has excellent command. The channel's overall condition and performance is good. Banks are in better condition with sufficient berm and free board. Hydraulically speaking, one can say that Gajjiani Disty is very sound and has a good security margin for operation and good potential for storage capacity in tempering the fluctuation inside the system. Permanent Features Gajjiani Disty offtakes from RD 38900 (right side) of Malik Branch. It is the major perennial distributary in Malik Sub Division designed with authorized discharge of 319 cusecs and total length of almost 27.99 canal miles. Water is distributed to secondary channels (minors) through 6 offtakes and 102 of direct outlets. It was designed with 45.2 ft W.S.W. in head reach with variation in bed slope from 1/5000 to 1/3046 ft. Design velocity was proposed as 1.74 ft/sec. with 4.4 ft F.S.D. It passes through a tract of land which is highly water logged and without proper drainage system. Total GCA/CCA, three year irrigation figures and detail of major crops are provided in Annexure-F. Water levels along the channel for improvement in command and efficiency are maintained through control points at Rd's 53200, 77250, 84000, 98750, 106200, 108980, 110900 and 138400 with excellent working head except falls Rd 77250 and 84000. For hydraulic data see Annexure-G. These two falls are non modular due to certain reasons. Head regulator is a gated mechanical structure with modular working. Discharge table is available but required rechecking. 13 Operational Issues Gajjiani Disty has good a working head while offtaking from the parent channel·. It can be fed with very low supplies in Malik Branch. Most of the channel reach is in high filling. It has excellent inner and outer prism. Under rehabilitation project, work for strengthening of banks with necessary provision of protection works, berm formation and brick lining in tail reach RD 114­ 139905 was done in the 1993-1994 financial year. Most of the outlets are APM and OFRB. This channel is required to run more than authorized due to certain reasons. One of the major reasons is the excessive withdrawal of offtaking channels and the discharge variation, which can be seen in Graph-X. Out of six offtaking channels, five are without regulation gates. The regulation is done by wooden Karries due to which it is very difficult to control the excess supplies especially in this political era. That is why, for the feeding of whole system as per A.F.S, in Kharif season, channel is required to feed more than authorized by about 15%. Additional supplies are also supplied to the irrigators for reclamation purposes. For detail of existing and last year supply see Annexure-F. This valuable supply can be saved by providing regulation gates at all offtaking channels. Chak Abdullah Minor is already provided with a regulation gate. The official rotational schedule is followed strictly as approved by the competent authority. The discharge at the head is most of the time higher than design discharge, leading to scouring of bed and erosion of sides in first two head reaches, giving less security margin for operation in these eroded sites, making loss in capacity and for potential storage of channel. Overall channel reach is in good shape. Moreover, offtaking channels are not taken into account in the rotation, which is a reason why the first few offtaking channels have a better performance than the offtaking channels in the tail reach. The targets or objectives of water distribution for these offtaking channels are not fixed and clear, leading to problems in the implementation of orders in the field for equitable and fair distribution among the offtakings as per share. This is further aggravated due to non optimization of data collection and analysis activities and non performance of evaluation process. A lot of responsibility for feeding the offtakings is left to gauge readers, who are not capable of making fair decisions for equitable distribution. No doubt, in routine management, they perform a good local control. But this local control cannot tackle the fluctuations that enter the system. Rather they are amplified by operations inside the sub­ division, where a lot of variable discharges were received at different tails. Due to this lack of control inside the system, the canal is almost never in steady state and gates at the head are operated at different intervals. Most of the channel has an excellent command, but some lift outlets also exist. Channel reach RD 8 to 11, 23 to 25 , 27 to 33, 66 to 73 and 82 to 84 is in cutting. Heading up of channel in low supply days with regulation karries have been 14 approved at RD 23000 for feeding some upstream lift outlets. The channel has siltation problems in various reaches. Especially reach RD 77-84 experiences a lot of silt deposits. There is a canal rest house (Gajjiani) situated at RD 93-94 (rifht side), which is in a good working condition. A telegraphic system is also available at Gajjiani, but nowadays it is not working. Data of the system in Gajjiani section are conveyed nowadays through Chak Abdullah, a telegraphic station on the Fordwah system. As explained above reach RD 98-139905 has excellent topography with lined portion in tail reach, but unfortunately I due to some constructional defects, lined reach is facing the following problems: a) Silt deposits b) Overtopping c) Weed growth However overall efficiency of the tail is good. There is no chronic tail shortage. After lining the tail reach, the tail outlets are successfully meeting the water requirements of Chishtian city. This channel has not much tendency of mishaps/breaches due to its strong outer prism. Although in rainy season, there is a tendency of closing the outlets, however due to lined tail portion, less number of mishaps can be observed as compared to channels having earthen section. The head reach of the channel impacts more on waterlogging as compared to the tail reach and soil has poor drainage properties. As the channel runs as per approved rotational program which means low discharges, in 2nd and 3rd preference, excessive berm growth can be observed in reach RD 53200 to 114000. Hydraulic structures need repair. Discharge tables at various offtaking points need rechecking. Details of layout, communication link and administrative control has been provided in Annexure­ B, D & E. 2.6 DHABAN MINOR Dhaban Minor is the first offtake of Gajjiani Disty with intensively water logged and salinity effected area in command. Lush green orchids and valuable fertile patches of land has suffered from water excess and people have no way for their survival. They are helpless and looking with some good expectations towards I&PD for their remedies. Permanent Features Dhaban minor offtakes from Gajjiani Disty at RD 17000/R with authorized discharge of 17 cusecs and a tail RD of 25470. The head regulator has not been provided with gate and gearing. The discharge table is missing. For detail 15 of total GCA/CCA, three year irrigation intensities. Major crops and outlets, see Annexure-F. There are 15 outlets. Four are lift outlets (pipes) whereas others are designed as OFRB. Hydraulic data at the head and tail is collected under supervision of SBE. Kot Sher Muhammad and conveyed to Bahawalnagar daily. The channel was designed with 10ft W .S.W. and 1.5 ft F.S.D. in head reach. Bed slope was to vary from 1/2857 to 1/2500. Water levels are maintained through two control points at Rd 8100 & 9100 which work modular. For information see Annexure-G. Operational Issues Perennially designed Dhaban minor has a sufficient working head while offtaking from parent channel and runs through a tract of land which is highly water logged, especially the tail reach. No tail shortage is observed. Some lift outlets are also provided on this channel. There is heavy Jungle/Sarkanda growth along the banks. This channel draw excessive supply even in the days of slake demand, when the water logged tail reach requires less or some time almost nil supply. This channel has to run full due to feeding of high level area and outlets in upper reach, so there is a wastage of valuable supply. For existing and last year supply conditions see Annexure-F. Channel has different topography in total run. Rd 0 to 7COO is balance, RD 7000 to 9100 is in cutting and RD 9100 to tail is in filling. Additional supply is also given for reclamation purposes. In rainy season, excess supply at tails is the major issue to be adhered. Silt deposits and heavy berm growth is also observed. As the head structure is without gate, regulation is done by wooden karries, and most of the time the discharge is higher than the design, leading to waterlogging itself and reduction in supply for the parent system in lower reaches. Banks are weak, giving lesser security margin for operation. Data collection and an'alysis activities are also not optimized. For information of layout, communication link and administrative control see Annexure-B, D & E. 2.7 THAKT MAHAL MINOR Thakt Mahal Minor is the 2nd major offtake of Gajjiani Disty. It irrigates a vast strip of land bounded by Fordwah Branch in the north, Gajjiani Disty and Chak Abdullah Minor in the south. Most of the commanded area is water logged and salinity effected. However some lush green orchids and very fertile land patches are included in the command. Permanent Features Thakt Mahal Minor was designed perennially for the distribution of 37 cusecs of discharge through 23 outlets designed as OFRB in total length of 8.2 16 canal miles. Detail of total GCA/CCA, number of outlets, major crops and last three year irrigation figures are provided in Annexure-F. The head regulator is without gate, but works modular. The discharge table is also missing. Falls at Rd 7000, 13000, 13860, 18500 and 22500 have excellent working head contributing a lot to maintain water levels in the total run and to improve command. For hydraulic data see Annexure-G. The data collection is supervised by SBE, Kot Sher Muhammad and conveyed to Bahawalnagar daily. For existing and last year supply conditions see Annexure-F. The channel was designed with 13 ft W.S.W. and 2 ft F.S.D. in head reach. Bed slopes were proposed to vary from 0.225 to 0.34 per 1000 ft. with variation in water levels from 524.18 to 499.00. Operational Issues Due to modularity and good availability of head excessive withdrawl is the major operational issue. There is no control over regulation due to non availability of regulation gates. Sometimes people/irrigators in the upper reach of the channel remove the regulation karries which are adjusted to control excess entry, to irrigate their fields without any departmental permission/ supervision due to which mishap/overtopping can be observed in some reaches. In rainy season, the tail reach is affected by excess supply pressure and channel regime disturbed. The bank position is good, but strengthening is needed in some reaches with necessary treatment to pucca and inner section. Topography is very interesting. Reach Rd 0 to 6500 is in cutting, Rd 6500 to 13000 is balanced and Rd 13000 to tail is in high filling with adjoining area water logged. Soil is of good nature in head reach and poor in tail reach with low properties of drainage. In rainy season, outlet closing tendency is observed. Silt deposits and growth of weeds can be noticed in low supply periods. Periodically re-sectioning is needed to feed tails. A number of outlets require readjustment. For more information of layout, communication link and ad ministrative control see Annexure-B, D & E. 2.8 CHACK ABDULLAH MINOR Chak Abdullah Minor is the major offtake of Gajjiani Disty with almost 13 miles length and difficult topography. Tail shortage and waterlogging are the basic problems. Operational Issues- Chack Abdullah Minor offtakes from Gajjiani Disty at RD 53200/R with authorized discharge of 56 cusecs and tail RD 65000.For detail of total 17 GCA/CCA, Irrigation figures and Major crops and outlets see Annexure-F. There are 28 direct outlets, out of which 4 are lift. Channel head is provided with regulation gate with discharge table which requires rechecking. Hydraulic data is collected under supervision of SBE, Gajjiani and conveyed to Bahawalnagar daily. There are falls at Rd 19390,22000,24000,25650 & 25850 with excellent head which have significant effect on command and maintain the water level in the total run. For detailed information of hydraulic data see Annexure-G. Channel was designed with 19.60 ft W.S.W. and 2.10 ft F.S.D. in head reach. Bed slopes were proposed to vary from 1/4444 to 1/3500. Operational Issues Tail shortage and water logging are the burning issues of this channel. Tail shortage is experienced due to certain reasons, especially the channel topography which is very interesting. Reach RD 0-4 is partly in filling and partly in cutting. Reach RD 4-21 is in cutting. This part of channel passes through high level sandy dunes. In summer season, when heavy wind storm carrying dust flows, this reach is abnormally chocked and silted up due to which channel regime is disturbed and capacity reduced with less security margin for operation and use of potential storage. The working head at offtaking point also suffers and flow varies from free orifice to submerged orifice which ultimately effects the with drawl from parent. The flow in the channel is most of the time on the margin and tail suffers with decrease in agricultural production. Although the channel has a gated structure with sufficient head, the silting up of the head reach and the fact that one offtaking channel at RD 8500 i.e. Madrissa sub minor has a good modularity than parent channel, fair distribution is not achieved and any fluctuation passed into the lower portion is difficult to temper. Some reclamation supplies are released to irrigators in Kharif, which has an additional impact on channel efficiency. In 1994-95 closure, no re-sectioning work was carried out in the head reach, which is why in the present flow season, Department has to face a difficult situation. By deputing regular establishment of Gajjiani and Kot Sher Muhammad sections to reach RD 9-21, the problem was treated upto some extent and supply at tail made up. In low supply days, berm formation/growth of jungle and weeds in tail reach are observed. Lengthy reach also has an effect on the tail. To overcome tail shortage and to save the department some hardship, a PC-1 (Planning Commission proform No.1) for brick lining of tail reach RD 49950 to 65000 (tail) has been prepared and submitted. Reach RD 22-65, which is in high filling is weak without berm and free board, giving a high risk in full demand and in rainy season, when upper reach irrigator's close their outlets, and heavy excess accumulate in tail reach. A number of overtopping cases has been observed. For existing and last year supply 18 conditions see Annex "F". Layout, communication link and administrative control has been provided in Annexure-B, D & E. 2.9 MADRISSA SUB MINOR Madrissa Sub Minor is an important offtake of Chak Abdullah Minor with excellent command. Adjoining area in tail reach is water logged without proper drainage system. Permanent Features Madrissa sub minor offtakes from RD 8500 of Chak Abdullah minor with an authorized discharge of 17 cusecs and a tail RD of 17590. There are 10 OFRB outlets on this channel. For detail of total GCA/CCA, Irrigation figures, major crops, outlets & existing/last year discharge conditions see Annexure-F. The head is not provided with a regulation gate and this discharge table is also missing. Data is collected under supervision of SBE, Gajjiani and conveyed to Bahawalnagar daily. There are falls at RD 2550, 2920, 7610 & 10500 for maintenance of water levels and improvements in command. For hydraulic data see Annexure-G. Tail reach is brick lined and there is no tail shortage. Operational Issues While offtaking from the parent channel, a sufficient working head is available for modular working. As the supply is controlled by regulation karries, this channel runs more than authorized which has adverse effect on tails of Chak Abdullah Minor (the paren channel). Reach Rd 0 to 3000 is in cutting and the soil is sandy. In summer season, when heavy wind storms carrying dust blow, this reach suffers badly and channel capacity decreases. Reach Rd 3000 to 7500 is in balanced condition with fertile soil and some weak sites due to trespassing and cattle ghats of nearby situated local abaddies. Reach Rd 7500 to tail is in filling with good bank position but having water logging and salinity problem. In rainy season, tail irrigators face excess supply problems due to closing of outlets in upper reach. For existing and last year supply conditions see Annexure-F. and for layout, communication net work and administrative control see Annexure-B, D & E. 2.10 KOKNI MINOR Kokni minor is a small but an important offtaking channel of Gajjiani Disty meeting with agricultural as well as domestic needs of the area under command. The channel command is good with some organized farming. 19 Permanent Features Kokni minor offtakes from RD 77250/R of Gajjiani Disty. Its total GCA/CCA, three year irrigation figures, outlets, and major crops are given in Annexure-F. Its authorized discharge is 13 cusecs with tail RD 12750 and W.S.W. 8.5 ft. There are 7 outlets (OFRB). Bed slope was proposed to vary from 1/2857 to 1/2500 with design velocity at 1.25 ft/sec. The channel has sufficient working head while offtaking from the parent channel. The head regulator is without gate and the discharge table is also missing. Hydraulic data of the head and tail is collected and conveyed to Bahawalnagar daily. There are falls at RD 4938,6400,6800 and 7300 with sufficient working head which provide excellent command to the area and maintain the water levels in total run. Working of these control points is modular. For hydraulic data of falls see Annexure-G. Layout of channel, communication network and administrative control has been provided in Annexure-B, D & E. Operational Issues As explained above, channel head structure is with out gate and modularity is good as compared to parent channel. The supply is adjusted by regulation karries, so excess authorized is the major issue which has adverse affect on tail of Gajjiani system as well as waterlogging after tail reach of the channel. Unfortunately, there is no proper drainage system, so very fertile and valuable agricultural land is being wasted every year. Channel topography is balance, but the head reach is in cutting. As no restoration work has been carried out on this channel since long, banks, berms and service road have deteriorated abnormally, leading to reduction in capacity. Silt deposits and weed growth are observed in the tail reach. In rainy season, irrigator's has to face excess supply. For existing/last year supply conditions see Annexure-F. 2.11 CHATALA MINOR Fortunately, Chatala minor has an excellent working head as compared to the parent channel. Due to this fact the command is good and channel efficiency is remarkable. It irrigates very fertile and lush green tracts of land with few large farms. Permanent Features Chatala minor offtakes from RD 77250/L of Gajjiani Disty with authorized discharge of 11.5 cusecs and a tail at RD 10250. There are 7 OFRB outlets. Details of total GCA/CCA, Major crops and three year irrigation figures are provided in Annexure-F. The head structure is without gate and the discharge table is missing. However, the head works modular. There is no fall available in the total run of channel to maintain the water levels, which is why tails are 20 in submerged conditions. Channel was designed with 6.6 ft W.S.W. and 1.6 ft F.S.D. with variation in slope 0.30 per 1000 ft. For layout of channel, communication network and administrative control see Annexure-B, D & E. Operational Issues Excessive withdrawl is the major issue due to unavailability of regulation gates which has dual affect i.e. 1) shortage at tail Gajjiani 2) water logging of area under command. Channel reach RD 0--5 is in balance topography and other reach is in filling. Heavy growth of Jungle/Sarkanda observed on right bank. The tail reach command area is water logged. There is no proper drainage system in this area. Tail irrigators face excess supply in rainy season. This channel often runs with a higher discharge than authorized. Data is collected under the supervision of SBE, GJN and conveyed to BWN daily through CAL tele-station. Tails are often in submerged condition. For detailed information of existing and last year supply see Annexure-F. There is no tail shortage experienced by the Department. In low supplies, this channel regime is disturbed due to excessive weed growth and increased silting tendency with decrease in channel capacity having adverse effects on tail in Kharif. Service road along left bank is lower than natural surface level, in rainy season inspection of channel becomes almost impossible and efficient control over channel con not be ensured. 2.12 CHISHTIAN MINOR Chishtian minor is the last offtake of Gajjiani Disty. It covers a very fertile and lush green strip of Chishtian Tehsil. Holdings are small, however some well and scientifically organized forming also exists. Permanent Features Chishtian minor offtakes from RD 98750/L of Gajjiani Disty with authorized discharge of 23 cusecs and tail RD of 33500. There is no gated structure provided at the head. The discharge table is missing. Total GCA/CCA, three year irrigation figures and major crops are given in Annexure-F. There are 14 OFRB outlets. Bed slope varies from 1/4444 to 1/4000 with designed velocity at 1.2 ft/sec. Data is collected under supervision of SBE, GJN. For existing and last year supply conditions see Annexure-F. There are falls at RD.5300, 17500, 27900 and 30100 with excellent working head for maintaining water levels and improving command. For detail hydraulic data see Annexure-G. Layout of the channel, communication network and administrative controls information has been provided in Annexure-B, D & E. 21 Operational Issues As explained above, channel has no gated structure but due to availability of excellent working head, it works free modular and even in low supplies it take its due share of supply from parent channel. But due to least control over tempering of fluctuation in parent channel, the discharge at head is most of the time lower than the design discharge, leading to siltation in the upstream reaches. This has resulted in a loss of the capacity of channel giving a smaller security margin for operation and very variable discharges are received at tails with almost non steady state of flow in channel. Initially, this channel had tail approximately at RD 38000, then tail curtailment was done and tail proposed at RD 33500. Tail irrigators again applied for shifting of their land on Fateh Disty (Tail offtake of Malik Branch runs parallel to Chishtian minor in this reach) and tail curtailment at RD 30100 was approved vide worthy SE, Bahawalnagar number 1832 dt 23/2/1995. As per decision, the sanctioned discharge at head is now 17 cusecs and at tail is 0.46 cusecs. This decision will be implemented in near future after observing formalities. The channel topography is excellent. Reach RD 0 to 16500 and 18000 to 25600 is balance in cutting and filling, where as remaining part of the channel is in high cutting. Channel has silting problems in reach RD 0 to 17500 where the tail reach is abnormally effected by weeds growth. Low supplies in 2nd and 3rd preference further adds toward chacing up the channel, thus reducing authorized carrying capacity. Banks are quite strong with necessary free board and berm. There is less effect of water logging on the channel command as compared to other Gajjiani system command. In rainy season, heavy excess due to closing of outlets in upper portion of Gajjiani system is experienced by the channel which some time causes over topping and breaching, but this occurs rarely. The rainfall also disturbs the regime in the cutting portion of the channel due to entering of muddy run off from high level surroundings. Erosion of banks is observed. However over all channel condition is satisfactory. For more information regarding existing and last year supply conditions see Annexure-F. 2.13 SIRAJWAH DISTY Sirajwah Disty is an important offtake at the tail of Eastern Sadiqia Canal. It replaces an old inundation (Malikwah) canal. It plays a vital role in agricultural sector of the area. The channel has an excellent prism. It provides facilities, for irrigation, drinking and other domestic needs of the area. Overall channel command is affected by water logging and salinity. Holdings of the people are small, but some well organized farms are contributing a lot in increasing the agricultural, social and economic values of the people. 22 Permanent Features Sirajwah Disty is designed perennially for 197 cusecs from the tail of Eastern Sadiqia canal RD 245000 as a component of the Sutlej Valley Project. At the head a gated structure is available. Flow conditions are submerged orifice. A discharge table is available but requires rechecking. At the tail it bifurcates into two minors namely Bahadurwah and Najibwah. Detail of total GCA/CCA, last three year irrigation figures are given in Annexure-F. Water is distributed through 36 direct outlets, most of which are OCAPM, OCOFRB, APM and OFRB. There are only two control points available in the total run, i.e. at Rd 21800 and 58825 with design working head 0.46 ft and 0.44 ft respectively to control the water levels and ultimately to improve command. For detail see Annexure-G. The channel has a total length of 13.54 canal miles with 36 ft water surface width at head and 25.2 ft at tail. Designed velocity varies from 1.48 ft/sec to 1.51 ft/sec. Bed slope provided 1110000 to 1/8000 per 1000 ft. Full supply level was proposed 538.50 at head and 530.20 at tail which has now been abnormally disturbed. Operational Issues Sirajwah Disty's flow is submerged orifice while offtaking from parent channel. The discharge at head is most of the time higher than design discharge, leading to abnormal distribution in inner prism with high siltation in head reach. Channel capacity is reduced up to dangerous limits. Feeding of the system under such circumstances is a major operational issue and department has to face hard time especially in Kharif season when demands are in full swing and additional reclamation supplies are also required. This channel runs parallel on right side of Hakra Branch. There is no proper drainage system in this area. Released reclamation supplies distributed among the irrigators in Kharif season to reclaim the affected soil is not of such quantity as actually required. High seepage rate from Hakra Branch and rain fall in monsoon further adds to water logging. Poor drainage is the basic problem of this area. Present alignment of the canal is the same as the alignment of old inundation canal which was the only source of irrigation in this area in 1860's. This fact is very clearly observed from the existing conditions. But, un­ fortunately, no strengthening work has been carried out since long due to which existing position is not very appreciable and this has resulted in a loss of the capacity, giving a smaller security margin for operation. As discussed above, there are only two hydraulic control points available on this channel to maintain water levels at RD's 21800 and 58825 with 0.46 ft and 0.44 ft design working head. This head suffered due to silting tendency and ultimately 1.55 ft rise in water level was observed in a survey conducted under personal supervision of undersigned in 1994. Due to this rise in water 23 level the falls are found to be almost non-modular and storage potential is not in use in present situation. Available free board is also little and not enough to pass authorized supply safely and number of overtopping/mishap cases have to be faced by the department. Heavy growth of jungle and sarkanda on 10 to 15 ft wide berm also provides hiding places for breeding animals which causes mishaps. Following are the maior issues to be dealt with. a) Desilting of channel to improve capacity and making falls modular. b) Removal and uprooting Sarkanda and Jungle. c) Strengthening weak sides of channel with necessary repair to pucca structures. d) Berm cutting. There are local villages situated along the channel in reach at RD 12-14 (right side), 46-48 (left and right side) and RD 59-60 (left side). These villages are in a low depression and the drainage system is poor with brackish ground water. Due to heavy trespassing and cattle ghats, the berm is under pressure and a permanent risk for mishaps exists. Most of the channel command is waterlogged, since whenever rainfall occurrs, irrigators close their outlets and heavy excess accumulates in lower reaches and the channel becomes under pressure. The official rotational schedule is strictly followed as approved by competent authority. However, the targets or objectives of water distribution are not clear, leading to problems in the implementation of orders in the field. Data at the head is collected by SDO Jalwala at regular intervals of 3 hours and conveyed to Bahawalnagar twice a day. Data at the tail of Sirajwah and head of Najibwah and Bahadurwah is collected and conveyed to Bahawalnagar daily. For more details regarding existing and last year supplies see Annexure-F. The process of data collection and analysis is not optimized, and the evaluation process is almost not performed at all. A lot of responsibility is left to the gauge readers, especially in case of emergencies. In routine management, they perform a good local control. But this control cannot tackle the fluctuation that enter the system. This results a highly variable discharge at tail. Administrative control of Sirajwah system, Communication link and Layout of canals has been provided at Annexure-C, 0 & E. 2.14 BAHADURWAH DISTY Bahadurwah is the major offtake of Sirajwah Disty. It has different nature of command. Water logging, salinity and variable discharge at tails are the basic 24 problems. Overall channel efficiency is not very appreciable. Holdings are small. However, some lush green orchids and well organized farms are included in the command. Permanent Features Bahadurwah minor is a perennial offtake at the tail of Sirajwah. It was designed for distribution of 82 cusecs of discharge through 50 direct OFRB outlets and one small sub-minor i.e. 1 IR Bahadurwah. Its total GCA/CCA, detail of last three year irrigation figures and major crops are given in Annexure-F. There is no regulation gate provided at the head. A discharge table is also missing. Most of the outlets are OFRB, however, some APM outlets also exist. It was designed with 22 ft water surface width, 3 ft full supply depth in head reach and 4.7 ft water surface width, 1.2 ft full supply depth in tail reach. Designed velocity proposed was 1.38 ft/sec to 0.80 ft/sec, while bed slope varies from 1/7500 to 1/5000 ft. Critical velocity ratio is kept at 0.82 with three control points to maintain water levels in the canal. From hydraulic data Annexure-G it reveals that only 0.4 design working head available at offtaking point. Control points at RD 18700, 23000 & 37300 are contributing lot in improving the efficiency of command in a total length of 12.03 canal miles. Hydraulic data at head and tail is collected and conveyed to Bahawalnagar daily under supervision of SBE, Sirajwah. Operational Issues Flow conditions are open channel due to non-modular working of the head structure and discharge is most of the time is lower than design, leading to siltation in the upstream reaches and highly variable discharge conditions at tails. This variability is further aggravated due to a topography which further creates hindrances. Reach Rd 2000 to 4900, 8500 to 25000 and 33000 to 37200 is in high cutting and passes through sandy dunes. In summer season, these reaches face problem of silting up, reducing the safe capacity, thus giving a smaller security margin for operation and becoming insufficient to pass the authorized supply. Channel reach RD 37200-55000 is in high filling and adjoining area is waterlogged. Banks are weak, without free board and berm. As explained in the case of Sirajwah Disty, whenever rainfall occurs, irrigators close their outlets and heavy excesses are received in the lower reaches with a lot of pressure on the channel section. So numerous mishaps, breaches, serious leakages cases are observed in the lower portion of the canal. This situation further adds to waterlogging of the area which is already abnormally affected and without proper drainage system. People of this area face a lot of problems for their survival and valuable agricultural land is also being wasted every year. However, some additional supplies are provided to irrigators for reclamation of their effected soil. Remedies for this aspect must be recommended. 25 When the system runs, in 2nd OR 3rd preference, excessive berm formation and siltation can be observed in various reaches. In reach RD 3-4 (left sife), 9­ 11 (left and right side), there are local abaddies settled along the channel. Tress passing and heavy cattle ghats also adds to widen the channel, so that ultimately low velocities create problems. In the tail reach unloading is the major issue. The working of tail outlets is modular. However, supplies at tails are not distributed as per targets and tempering of this is very difficult. The rotational schedule is followed but the sub-minor has no control, which is a reason why it has a better performance than parent canal. The sub-minor which offtakes from RD 18100 with an authorized discharge of 3.51 cs and a tail at RD 5010 also passes through high level sandy dunes and faces a number of problems. Unloading, silt clearance and stable section are the major issues. Total GCA/CCA is 935/911 acres irrigated with 2 outlets which work modular. For existing and last year supply conditions see Annexure-F. Layout, Communication set up and Administrative control has been provided at Annexure-B, D & E. 2.15 NAJIBWAH MINOR Najibwah Minor is an important offtake of Sirajwah Disty. It irrigates a very fertile strip of land in Bahawalnagar tehsil as well as meeting with the drinking antd other domestic requirements of Donga Bonga town. It is playing an important role in increasing the agricultural production of the area. Holdings are small, but some big and well organized farms are also included in the command. Permanent Features Najibwah minor offtakes from the tail of Sirajwah Disty at RD 61100/L with authorized discharge of 39 cusecs with its tail at RD 56315. The channel head works modular but without gate. The discharge table is missing. There are 23 outlets, mostly designed as OFRB. For detail of total GCA/CCA, number of outlets, major crops and three year irrigation figures see Annexure-F. The channel was designed with 13 ft W.S.W. in head reach and 4 ft W.S.W. in tail reach with variation in bed slope 1/5000 to 1/3000. The designed velocity was kept 1.34 to 0.80 ft/sec. with 1.5 ft free board. The water level varies from 528.30 to 512.80 in the total run, but hydraulically only one control point is available to maintain water levels. For detail of data see Annexure-G. Hydraulic data at head and tail is collected under supervision of SBE,. Sirajwah and conveyed to Bahawalnagar daily. 26 Operational Issues The channel has excellent working head while offtaking from the parent channel. It mostly runs in excess, leading to disturbance in inner prism. At head no regulation gate is provided, so the supply is adjusted by regulation karries and lot of difficulties are experienced in balance running of channel. The topography is balanced with surrounding area badly waterlogged without a proper drainage system. The soils have poor drainage properties. The channel's overall condition is very deteriorated. The banks are very weak without free board and berm, reducing the capacity, and the security margin. In the rainy season, the outlets tend to be closed, which exerts heavy pressure on lower reaches, and number of overtopping/mishapes have been observed. In Kharif season, when reclamation supplies are released to irrigators the pressure on the channel is further aggravated and the department has to face a difficult situation. The second reach is very weak, and potential storage is not used leading to a variable discharge at tails and targets or objectives of equitable and fair water distributions are not achieved. It is also impossible to temper any fluctuation that enters the system. The official rotational program is followed and this canal has a better performance than the other minor offtaking from the same point. Data collection and analysis process are not optimized, and the evaluation process is almost not performed at all, which is the reason for the difference in efficiency of canals offtaking from the same point. A lot of regulation responsibility is left for the gauge reader which is not fair. He is good in routine management, but in decisions making factors, it is not always appreciable. The operation inside the system has a big scope for improvement. By keeping the present security margin, many artificial fluctuations can be suppressed, stabilizing the discharge at tails. Donga Bonga Canal Rest House is situated at RD 18-19 (left side), The telegraphic station is also situated at Donga Bonga. Data of Sirajwah system are conveyed to Bahawalnagar through this telegraphic station. Details of communication link up, administrative control and layout of channel has been given in Annexure-B, D & E. 27 CHAPTER: 3 RESEARCH PROBLEMS & APPROACH 3.1 PROBLEMS From precise study of canals in chapter 2, the difficulties/problems being faced by the Department can be categorized under four major heads. a) Information and Maintenance b) Information and Operation c) Sediment Transport d) Waterlogging and Salinity a) Information & Maintenance One of the major problem with PID incharge staff is to identify the actual and exact issues. Lack of modern and scientific Engineering implements, well polished and experienced staff are the major drawbacks to collect existing data and then to propose correct remedy. However, if correct information may be found out then availability of funds is a separate issue. This situation is very dangerous and alarming. Following are the major issues linked with maintenance: Weak and poor bank conditions Non availability of proper berm and free board Jungle/sarkanda growth Excessive berm formation Abnormal erosion and scour Trespassing and cattle ghats Desilting Adjustment of outlets Repairing of head regulators and damaged pucca structures Replacement of bridges slabs Fighting against overflow, mishaps, breaches and cuts Fighting against heavy wind storms carrying dust and sand Fighting against heavy seepage rate Constructional defects in lined reach of Gajjiani Disty Reaches where local abaddies are situated alo'ng the channels b) Information and Operation This is the major burning issue of the time and the PID is facing hard time in the shape of tail shortage. Any research in this field will definitely help the Department to overcome this issue. Malik Sub-Division is also facing tail 28 shortage and non equitable distribution of supply on some selective channels due to the following reasons: Poor communication system Non gated offtakes Fluctuation in the system Non availability of discharge tables Non availability of upstream and downstream gauges Escape channel to take care of excess supply in emergency and rainy days Distribution of supply when one reach has slack and other keen demand Feeding of high level channels and lift outlets Distribution of reclamation supplies Change of indent place from Rd 38900 to 95900 Malik Branch for Dahranwala Sub-Division Excessive withdrawal of offtaking channels c) Sediment Transport Sediment Transport is an important and major issue which requires special attention and care as the channel's valuable and efficient life depends mostly on its behavior. This is a major subject and a separate detailed report is needed for understanding the complete phenomenon. However, some channels are facing problems due to the following reasons: Excessive and abnormal silt entry Non achievement of critical velocities in low supplies Non drawing of fair share of silt of offtaking channels and direct outlets Channels that are passing through sandy tracks and are in cutting Channels having abnormal widened section Channels with structure with submerged flow conditions d) Water Logging and Salinity Water logging and salinity is the major issue for the Pakistan's agricultural land. Very fertile and lush green tracts of land are being wasted every year. This factor is contributing a lot to decrease the social and economic values of the population of Pakistan directly linked with agriculture. This is also one of the major issue being faced by PID in this sub-division. Overall channels command are water logged. Main factors are: Soil with poor drainage properties Non existence of proper drainage system Poor and improper working of existing drainage system Heavy seepage rates from canals 29 Over irrigation Heavy rain falls and improper handling of run off Heavy floods 3.2 APPROACH For all these problems and issues discussed above a precise study is needed to be carried out topic wise. Different approaches and methodologies are required to be developed on modern and scientific lines, so that the existing positions of channels and available supplies can be improved. This will not only help the PID for better and equitable distribution among the irrigators but it will also help to increase agriculture, social and economic values of the GOD gifted country which is the need of time now in this era of "Population Explosion". In a first step gauges have been replaced by Department and efforts are made to update ratings tables. By implementing an information system (IMIS - Irrigation Management Information System) through which daily information of discharges is secured and all structure characteristics (dimensions, crest level, rating~ are incorporated, the Irrigation Engineers will be provided with a better information handle. Also a further fine polishing of the skills of technical staff will be undertaken. Then more precise studies will be formulated to find a solution for the problems listed in the previous section. For more details of the approach being followed, consult the Workplan 1996. 30 REFERENCES 1.
