Abstract:
Flood disaster was simulated in Cao Shui Basin in Jiangxi Province. By revising the Digital Elevation Model (DEM) with river raster layer in, flooding simulation results carried out by FloodArea hydrological model was compared by deterministic coefficient and Nash Sutcliffe efficiency coefficient with the actual flooded traces and hydrological data from hydrological observatories during 2000-2010. The results showed that based on the embedded river raster DEM, flood disasters simulation process is significantly associated with the moving route, submerged area and depths of floods are caused by severe precipitation. The method can be used as a basic way to simulate the flood disaster caused by critical areal precipitation.
