Abstract

Recently, the patterns of climate change-induced disasters have become more diverse and extensive. To develop an effective flood control plan, Korea has incorporated the concept of Potential Flood Damage (PFD) into the Long-Term Comprehensive Water Resources Plan to assess flood risk. However, concerns regarding the PFD have prompted numerous studies. Previous research primarily focused on modifying and augmenting the PFD index or introducing new indices. This study aims to enhance the existing flood control safety evaluation method by utilizing a flood risk map that incorporates risk indices, specifically focusing on the Yeong-Seomjin river basin. The study introduces three main evaluation approaches: risk and potential analysis, PFD and flood management level analysis, and flood control safety evaluation. The proposed improved evaluation method is expected to be instrumental in evaluating various flood control safety measures and formulating flood control plans.

최근 기후변화로 영향으로 재해의 양상이 다양화 및 대형화되고 있다. 이에 우리나라는 안전한 치수계획을 세우기 위해 수자원장기종합계획에서 홍수위험도 평가를 위해 홍수피해잠재능(Potential Flood Damage, PFD)의 개념이 도입되었다. 하지만, PFD의 문제점이 제기되면서 다양한 연구들이 진행되어왔다. 선행연구 대부분 PFD 인자를 수정·보완하거나 인자를 새로 추가하는 연구들이 진행되었다. 본 연구는 위험성 인자를 내포하고 있는 홍수위험지도를 사용하여 기존의 치수안전도 평가방법을 개선하고, 대상지역인 영·섬진강권역을 중심으로 평가하고자 한다. 본 연구에서 제시한 평가방법은 위험성 요소 및 잠재성 요소 분석, PFD 및 홍수방어수준 분석, 치수안전도 평가로 크게 3가지로 제시하였다. 본 연구에서 제시한 개선된 평가방법은 각종 치수안전도 평가 및 치수계획 수립시 활용될 것으로 기대된다.
