Application of the Urban Flooding Forecasting by the Flood Nomograph

Abstract

Increased impervious area resulting from urbanization with Increased occurrence of heavy rainfalls under the influence of climate change due to global warming has become a cause of repeated flooding damage of the city area. The urban flood forecasting system is one of the useful alternative to minimize urban flooding damage. In this study, using a Flood- Nomograph built for flood prediction from rainfall intensity and duration was evaluated the applicability of prediction on urban flooding. The results showed that F-N was useful nomograph to predict flooding if adopted to the Urban flood forecasting system.

Key Words: SWMM; Urban flood forecasting system; Flood nomograph; SWMM; Flood prediction

요지

지구 온난화에 의한 기후변화의 영향으로 집중호우의 발생 증가와 함께 도시화로 인한 불투수면적의 증가는 도시지역에서 홍수피해가도시침수를 최소화하기 위한 유용한 대안 중 하나가 도시 홍수예보시스템이다. 본 연구에서는 강우강도와 지속시간으로부터 침수 예측을 위해서 구축된 Flood-Nomograph를 이용하여 도시 침수예측에의 적용성이 평가되었다. 연구결과 F-N을 도시 홍수예보시스템에 도입하여 활용한다면 침수예측에 유용한 것으로 나타났다.
