Abstract

In this study, we propose a new method for evaluating the vulnerability to flooding river levee. The purpose of this study is to examine how to apply the factors necessary to calculate the proposed levee flood index. To do this, the safety flood level was analyzed by applying the planned flood level. The levee flood vulnerabilities index was calculated based on seven factors such as freeboard, levee crown section, levee section ratio, safety factor, raised spot length, Seepage line change degree, and critical velocity. The Levee Flood Vulnerability Index(LFVI) of the levee developed in this study was used to levee vulnerability analysis. The results of the analysis were divided into 1 to 7 grades using Levee Flood Vulnerability Index(LFVI).

본 연구에서는 하천 제방에 대한 홍수취약성을 평가하는 새로운 기법으로 제방홍수취약성지수를 제안하였고 제방홍수취약성 지수를 산정하는데 있어 필요한 인자를 적용하는 방법에 대하여 알아보고자 한다. 이를 위해 먼저 대상 제방의 계획홍수위를 적용하여 제방의 안전율을 분석하였고, 제방의 인자들로는 여유고, 둑마루폭, 제방단면의 비, 활동안전율, 턱(소단)의 길이, 침윤선 길이 비, 한계유속으로 7가지의 인자들을 바탕으로 제방홍수취약성지수를 산출하였다. 이를 활용하여 제방의 취약성 분석을 실시하고 분석결과를 제방홍수취약성지수(Levee Flood Vulnerability Index, LFVI) 값을 이용하여 1~7등급으로 나누어 제방의 취약성을 평가하였다.
