Title: A Study on Water Supply and Demand Prospects for Water Resources Planning
Abstract: In this study, we suggest various improvement measures for water balance analysis, a basic step in water resources planning. First, we confirmed the assumptions and problem of the water balance method currently being carried out in Korea and suggest five methods to solve these problems. In order to analyze the applicability and the effectiveness of the proposed improvement measures, 10 cases were constructed using two rainfall-runoff model simulation results for the Geum River basin. Water supply and demand networks were constructed reflecting five proposed improvement measures and two simulation results, and conducted a water balance analysis. The results of the analysis of each case show the degree of improvement by comparing and analyzing the observed discharge of Gongju and Seokhwa points which are representative points in the Geum River basin. The applicability of the improvement measures was confirmed through comparison and examination with the past restricted water supply area. More realistic analysis will be possible when establishing water resources planning through the proposed water balance method in this study.
