Abstract

In this study, flood analysis was conducted to prepare for damage caused by typhoons and heavy rain due to abnormal climate and climate change. Two - dimensional flooding analysis using the FLUMEN model, which is widely used for national and international flood risk mapping, was conducted for the Nam River Basin, which is the tributary of the Nakdong River. This study divides the topography into $5m{\times}5m$ DEM by ArcView, so that the accuracy of river repair and hydrological characterization and flood area identification can be maximized. As a result of simulation of water flooding, 163.3ha in section 1, 227.7ha in section 2 and 59.9ha in section 3 were simulated.

본 연구에서는 이상기후 및 기후변화에 따른 태풍, 집중호우 등으로 발생할 수 있는 피해들을 대비하고 상황에 맞는 대응을 위한 침수분석을 하였다. 연구대상지역은 낙동강의 지류인 남강유역에 대하여 국 내외 홍수위험지도 작성에 널리 이용되고 있는 FLUMEN 모형을 적용한 하도 및 제내지의 2차원 침수해석을 실시하였다. ArcView에 의해 지형을 $5m{\times}5m$의 수치표고모형을 생성하여 하천의 수리 수문특성 분석 및 침수지역 식별의 정확성을 최대한 확보할 수 있도록 하였다. 침수 모의 결과 1구역에 163.3 ha, 2구역에 227.7ha 그리고 3구역은 59.9 ha의 침수가 발생한 것으로 모의되었다.
