홍수취약성을 고려한 치수 투자우선순위 결정 방안 = A Study on Determination of Investment Priority of Flood Control Considering Flood Vulnerability

국문 초록 (Abstract)

본 연구의 목적은 유역내에서 치수 투자우선순위를 효과적으로 결정하기 위한 방안을 제시하는 것이다. 현재 수자원장기종합계획에서는 홍수취약성 평가 방법으로 홍수피해잠재능(PFD)과 홍수위험도 지표를 제시하고 있으며, 대상 지역의 홍수 취약 정도를 나타내는 척도로 사용되고 있다. 본 연구는 치수투자우선순위를 결정하기 위해 개선된 홍수 취약성 평가 방법을 이용하고자 기존을 비롯한 AHP(Analytic Hierarchy Process) 및 엔트로피 이론에 의한 요소별 가중치를 산정하고 대상 유역별 최종 홍수 취약성 지수를 산정하였다. 산정된 홍수 취약성 지수를 바탕으로 유역별 치수 투자우선순위를 결정할 수 있었으며, 치수 사업 시나리오를 적용하여 홍수 취약성의 변화 경향성과 사업의 기대 효과를 분석하였다. 그 결과, 기존의 홍수취약성이 높은 유역의 취약성 개선 효과와 함께 유역 전반에 걸쳐 취약성 불균형의 감소효과를 기대할 수 있었다.

The purpose of this study is to suggest a way to determine effectively investment priority for flood control in a region. Potential flood damage(PFD) and flood risk indices were proposed from the national water resource plan. They have been used as the methods for assessing flood vulnerability. This study estimates the flood vulnerability index in each sub-basin after calculating weights on factors of the methods by using existing method, AHP(Analytic Hierarchy Process) and entropy theory. Based on the estimated index, investment priority of flood control in the basin was determined. The tendency of flood vulnerability and the expected effect of business was analyzed through the scenarios on applying flood mitigation projects. As a result, it was expected that the imbalance of the vulnerability was reduced in the watershed with the improvement of the vulnerability in the sub-basins which had the high flood vulnerability.
