Optimal Planning of Irrigation Distribution and Application Systems for a Large Irrigated Area

摘要

Techniques were developed and applied to a large irrigated area near Idaho Falls in an attempt to obtain optimal solutions for multi-objective planning of this area. The techniques were developed to effectively inventory the area, determine the costs and operating characteristics of irrigation system components, and to obtain optimal system plans using mathematical programming. The mathematical model procedures resulted in optimal irrigation system plans which were based on different specified constraints (e.g.: overall system efficiency; water delivery cost to the system at the headgate; water diversion cost from the distribution system to on-farm application systems). The results were used to determine costs and configurations needed to meet specified efficiency levels.
