Document Type: Journal Paper


Studies in water resources planning and utilization have emphasized the need to critically evaluate the efficiency of irrigation projects. Evaluation of irrigation efficiency requires the delineation of necessary and beneficial water uses, uniform evaluation procedures, and acceptable standards for comparative purposes. Necessary and beneficial uses of water for irrigation are defined, along with practical and economical methods for evaluating irrigation efficiency. Examples are presented to illustrate the probable accuracy of various measurements used to evaluate irrigation efficiency. Alternative methods for evaluating components affecting irrigation efficiency are presented.
