As an important water conservancy project,reservoirs play an important role in flood control and disaster reduction,and are also related to the safety of people's lives and property,as well as sustainable economic development of the downstream of the reservoir.This article proposed an analysis method for flood inundation and evolution process in the downstream of the reservoir based on DEM.This method was applied to in the downstream area of Zhougongzhai Reservoir.The results show that the method can improve the analysis efficiency of the flood routing process,and can re-alize the process simulation of the flood inundation in the downstream of the reservoir.The simulation results conform to the flood inundation evolution law of rivers in mountainous areas.This method can provide data reference and technical support for the formulation of flood defense plan,the release of flood risk early warning,and the development of risk a-voidance and transfer work.
