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.
Key Words: Water Supply and Demand Prospect, Water Resources Planning, Water Balance Analysis
요지
본 연구에서는 수자원계획 수립을 위한 기초단계인 물수지 분석에 대해 다양한 개선 방안을 제시하고자 하였다. 먼저 국내에서 수행되고 있는 물수지 분석 방법에 대한 가정과 문제점을 확인하고 이를 해결할 수 있는 다섯 가지 개선 방안을 제시하였다. 제안된 개선 방안의 적용성 및 효과를 분석하기 위해 금강유역을 대상으로 두 가지 강우-유출 모형 모의 결과를 활용한 총 10개의 case를 구성하고 이를 반영한 물 수급 네트워크를 구축하여 물수지 분석을 수행하였다. 각 case별 분석 결과 중 금강유역의 대표지점인 공주와 석화지점의 관측유량과의 비교⋅분석을 통해 개선방안의 효과를 제시하였으며 과거 제한급수지 역과의 비교⋅검토를 통해 개선방안의 적용성을 확인하였다. 본 연구에서 제안된 물수지 분석 방법을 통해 향후 수자원 계획 수립 시 보다 현실적이고 타당한 계획 수립이 가능할 것으로 기대된다.
핵심용어: 물 수급 전망, 수자원계획, 물수지 분석
