Abstract

본 연구에서는 기후변화에 따른 홍수 취약성 평가기법을 제안하고 국내 5대강 유역에 적용 및 평가하고자 하였다. 특히 Multi-Model Ensemble 시나리오를 이용하여 평가 시 발생하는 불확실성을 제시하고자 하였다. 취약성 평가를 위해 우선 유역의 기상, 수문 자료를 비롯한 지형, 인문 사회 정보를 수집, 지표를 산정하여 현재 기후상태 하에서의 홍수 취약성을 평가하였다. 또한 기후변화에 따른 미래 홍수 취약성을 평가하기 위해 기존에 3개 온실가스 배출시나리오, 13개 GCMs (Global Climate Models), 3개 수문모형(2~3개 증발산량 산정방법)으로 생산된 39개 미래 기후시나리오 및 312개 미래 수문시나리오를 이용하여 기준 S0 (1971~2000년) 기간 대비 미래 S1 (2010~2039년), S2 (2040~2069년), S3 (2070~2099년)기간의 홍수 취약성의 시공간적 변화 및 불확실성을 평가하였다. 평가 결과 현재 기후상황에서 홍수에 취약한 지역은 한강, 섬진강, 영산강 하류 지역으로 나타났으며, 미래 기후변화 시나리오를 고려한 결과 낙동강, 금강, 한강 권역에서의 민감도가 가장 크게 변할 것으로 분석되었으나, 기본적으로 섬진강 유역의 적응능력이 낮기 때문에 미래에도 섬진강 유역이 홍수에 가장 취약할 것으로 분석되었다. The purposes of this study are to suggest flood vulnerability assessment method on climate change with evaluation of this method over the 5 river basins and to present the uncertainty range of assessment using multi-model ensemble scenarios. In this study, the data related to past historical flood events were collected and flood vulnerability index was calculated. The vulnerability assessment were also performed under current climate system. For future climate change scenario, the 39 climate scenarios are obtained from 3 different emission scenarios and 13 GCMs provided by IPCC DDC and 312 hydrology scenarios from 3 hydrological models and 2~3 potential evapotranspiration computation methods for the climate scenarios. Finally, the spatial and temporal changes of flood vulnerability and the range of uncertainty were performed for future S1 (2010~2039), S2 (2040~2069), S3 (2070~2099) period compared to reference S0 (1971~2000) period. The results of this study shows that vulnerable region's were Han and Sumjin, Youngsan river basins under current climate system. Considering the climate scenarios, variability in Nakdong, Gum and Han river basins are large, but Sumjin river basin had little variability due to low basic-stream ability to adaptation.
