Abstract
AbstractThe objective of this study was to assess the water delivery performance of the Som Kamla Amba irrigation scheme located in the Dungarpur district of Rajasthan using adequacy, equity and dependability indicators. Three minors each at the head, mid and tail sections of main canals (Right and Left Main Canal) and branch canals (Aspur Branch Canal and Baroda Branch Canal) were selected. The ratio of water delivered (obtained from discharge measured at outlets) and water required (calculated from CROPWAT software) was determined for major rabi crops (wheat, barley, gram and mustard) grown in the command area in 2011–2012. Results had shown good (1.00 to 0.93), fair (0.84 to 0.80) and poor (0.42 to 0.18) adequacy at the head, mid and tail sections of each canal respectively. Also there is poor equity in water delivery as its value varied from 0.35 to 0.92. Dependability was found to be good at head, fair at mid and poor at tail sections. © 2018 John Wiley & Sons, Ltd.
