Describes and explains detailed procedures for field evaluation of the performance of several types of sprinkle, surface, and trickle (drip) irrigation systems and of management practices for use by irrigators, land managers, technicians, and students. Step-by-step instructions are provided for gathering data in the field, and sample studies are presented that demonstrate the entire process. The introduction states and explains the general concepts of uniformity, efficiency, and management that are used in evaluating each system and improving their use. Individual chapters describe procedures for both full and simple evaluations of performance of the various irrigation systems. Most chapters include lists of equipment needed for performing these evaluations, and contain sample forms for recording and organizing field data. Analyses and recommendations for a few actual case studies are also included.
