연안도시 내수침수 피해저감을 위한 예⋅경보 체계 구축: 여수시를 중심으로

Frequent typhoons and localized heavy rains are becoming more frequent owing to climate change and global warming. In coastal cities, more damage is caused by rising sea level and high waves. For this reason, considering the rainfall conditions combined with the rise in sea level, we presented flood forecasting criteria for coastal cities. The scenario was applied to the Yeosu area, and was analyzed through the criteria of the decree selected at that time. In order to analyze the selected scenario, the XP-SWMM model was applied and the standard based on the inundation alarm was analyzed. Even if the area was located in Yeosu City, the appearance of the table of the inundation alarm differed depending on the topographical characteristics. Considering these characteristics, it is necessary to manage the criteria for inundation forecasts in coastal cities by subdividing them for each region.
