Abstract

This study develops a simulation model that performs flood analysis considering both urban and river flood. For the analysis of river flood, this study considers river overflow by levee breach, and reflects the concept of the dual drainage systems for the analysis of urban flood. In relation to the surface flood analysis, FEM technique is applied to the flood diffusion analysis in order to conduct the flow analysis of urban and river flood simultaneously. For the verification of the model, it is first applied to the conceptual model, and then applied to the actual watershed. It is expected that this study will be able to reduce flood damage and to prepare effective countermeasures to reduce flood damage.

본 연구에서는 내외수 범람을 동시에 고려하여 침수해석을 수행하는 시뮬레이션 모형을 개발하였다. 외수 침수해석을 위해 제방 월류 및 파제에 의한 하천범람 유입량을 고려할 수 있도록 하였고, 내수 침수해석을 위해서 이중배수체계 개념을 반영하도록 구성하였다. 지표면 침수해석과 관련하여 하천의 유동해석과 제내지의 유동해석을 통합적으로 수행하기 위해 유한요소법(FEM)을 적용하여 침수확산 해석을 수행할 수 있도록 하였다. 모형의 검증을 위해 우선 개념모델에 대해서 적용하였고, 이어서 실제 유역에 대해서 적용하였다. 본 연구를 통해 홍수로 인한 피해를 줄이고 홍수 피해를 저감하기 위한 효과적인 대책을 마련하기 위해 활용될 수 있을 것으로 기대된다.
