文章以江西省曹水作为山洪灾害淹没模拟的研究区域，通过嵌入河道栅格修订数字地形，采用 FloodArea 水文淹没模型对数字高程模型（Digital Elevation Model，DEM）对修订前后的同一降水过程进行模拟，结合实地考察流域内淹没痕迹和水文站水位资料对比分析两者的模拟结果，并利用确定性系数和 Nash-Sutcliffe 效率系数对2000-2010年间出现的强降水过程的模拟结果进行验证。结论表明：基于嵌入河道栅格的山洪灾害淹没模拟能较好地反映曹水流域内的因降水导致的山洪推进路线、淹没范围及淹没水深，该方法可作为推算曹水流域的山洪灾害致灾临界面雨量的基础。

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.
