Irrigation is a necessity in the Punjab, and water, in terms of timeliness, reliability and quantity is one of the limiting factors for an increase in agricultural production. The performance of the system is widely found poor in terms of delivering water surface resources according to the official water allocation and scheduling. Canals are almost never in steady state and fluctuations entering the system are amplified by numerous operations at cross regulators. This leads to a high number of breaches, and to an increase in the variability and unreliability of the supply at the secondary level. This study aims at evaluating the effect of operations at the main canal level on the water distribution to distributaries, and propose alternative rules of operations at a local level that can help the irrigation managers meeting their targets more effectively. It focuses on the tail part of Fordwah Branch, located in the Chishtian Subdivision.
