ABSTRACT

Agricultural water accounts for more than 60 percent of water resources in South Korea. The efficient management of agricultural water requires a system that analyzes the data to improve water efficiency, including water supply and demand throughout the watershed, water supply capacity of each facility in the watershed, water shortage in the watershed, and the possibility of developing additional water supplies. WBSIr, developed in this study, is optimized by applying a multi-purpose genetic algorithm in estimating parameters of the spill model, and the TANK model can be applied to each watershed if actual runoff is measured. Based on the WBSIr analysis of water balance considering an irrigation water supply network in the basin, it is possible to allocate water to each watershed more efficiently than the previous method. In comparison to the conventional water balance method, the water balance analysis considering the irrigation water supply network was found more reliable in the assessment of water supply.
