Systems analysis of on-farm irrigation systems. Research technical completion report Item Info

An irrigation systems analysis procedure has been developed for the purpose of critically evaluation on-farm irrigation system plans and water management practices under New Zealand conditions. The procedure incorporates agronomic information along with irrigation system operating characteristics and costs. Management practices and water supply inputs are also considered. The entire procedure is a computerized model written in Fortran 77. The entire procedure consists of (1) a preliminary analysis, (2) details of system component costs and operations, and (3) a simulation of system operation. In the preliminary analysis, the statistical variation of peak irrigation water requirements is computed. This information is used to estimate system capacity along with irrigated area and/or cropping pattern while considering the level of risk involved. The system component information includes details of crop rotation, plant-soil-water relationships and irrigation priorities. Operating characteristics and costs including two separate loan terms are computed for all irrigation system components. Simulation of system operation determines how an irrigation system functions over a period of time in supplying irrigation water requirements and the costs involved. Results produced by the procedure are designed to show the adequacy of irrigation for each crop in the rotation, irrigation system performance and the causes of any inadequacies in irrigation, and system cost.
