Methodology for Optimization of an Irrigation System with Storage Reservoirs

摘要

The study's objective was to utilize probability analysis and mathematical programming in planning the design and operation of an irrigation network with a chain of internal water storage reservoirs. Specific objectives were to (1) determine the best irrigation intervals and field water requirements during peak water consumption by a stochastical analysis of potential evapotranspiration, and to complete a cost-benefit analysis of the irrigation application subsystem; (2) specify locations and sizes of internal water storage reservoirs and compute design capacity of each segment of the irrigations distribution subsystem for the optimal least cost system. An area of approximately 1,865 ha in the Snake River Valley Irrigation District was selected for application of the proposed model.
