基于嵌入河道栅格的山洪灾害淹没模拟
Simulation of Flood Disasters Based on Embedded River Raster
摘要
Abstract
Flood disaster was simulated in Cao-Shui Basin in Jiangxi Province.By revising the Digital Ele-vation 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 re-sults showed that based on the embedded river raster DEM,flood disasters simulation process is signifi-cantly associated with the moving route,submerged area and depths of floods are caused by severe precipi-tation.The method can be used as a basic way to simulate the flood disaster caused by critical areal precipi-tation.关键词
