The aim of this paper is to develop a physical based distributed run-off model for flood simulation considering spatially and temporally varied rainfall and to evaluate the feasibility of an offline mode under typhoon and convective storm events for Korean watershed. Additionally, an auto calibration method for initial soil moisture conditions that have an effect on discharge was proposed, and Namgang watershed (2,293km2) was applied as study site. Distributed rainfall according to grid resolution was generated by using a preprocess program of radar rainfall from the JNI radar. Also, GIS hydrological parameters were extracted from basic GIS data such as DEM, land cover and soil map, and used as input data of the model. The Namgang watershed was divided into square grids of 500m resolution and calculated by kinematic wave into an outlet through channel networks to evaluate capability of the developed model. |
