Development of a Coupled Model for the Flood Inundation Simulation

홍수범람모의를 위한 내외수 연계모형 개발

The purpose of this study is developing a coupled model for the flood analysis. Firstly, the model(river model) describing the inundation in a river solves the two-dimensional Saint Venant equations with a finite difference method and it is possible moving boundary treatment. The other model(inland model) in developed based on the ILLUDAS model to describe the conveyance capacity of a stormwater sewer system. Finally, a coupled model is applied to a real situation. The newly developed coupled model simulates reasonably the flood event occurred in a river and a inland simultaneously
