Performance Evaluation of Water Delivery System for Command Area of Left Main Canal of Bhimsagar Irrigation Project, Rajasthan

Abstract

Water delivery performance of left main canal of Bhimsagar irrigation project, Rajasthan was studied. Outlet-wise performance was evaluated using the adequacy, equity, dependability, relative irrigation supply and relative water supply indicators. These indicators were studied for the 21 outlets located on three minors at head, middle and tail reach of the left main canal for the 5-month irrigation period during Rabi season, using measured water deliveries and calculated crop water requirements. The outlet-wise water delivery performance indicators showed poor performance of the system. Considering the irrigation season and the system as a whole, the average value of indicator’s were found as “poor†for adequacy, equity and dependability; emphasizing for adopting improved management strategies.
