| Abstract | In the command areas of large irrigation projects water is supplied through a net work of the canals and related structures. Different project s follow different delivery patterns . Simulation models were developed to study the irrigation schedules required in canal command area. The crops selected were paddy and sugar cane. To predict the net irrigation demand and minimum interval for the paddy, the amount and the interval of irrigation were analyzed at the different active storage and freeboard during the different growth stages. Irrigation schedules for sugarcane were developed based upon the allowable soil moisture depletion level. The results of both the mode ls were used to predict the net irrigation water required and ultimately the water use efficiency and tertiary unit efficiency for the selected plots and outlets. In this way the study gives the procedure for evaluating the tertiary efficiency which i s .useful for understanding the water us e in different outlets of a large irrigation project. The irrigation schedules predicted by the mode l were compared with those actually followed by the farmers. |
