| Abstract: | Floods have great impact on the development of the national economy , endanger people's lives and property , and destruct the ecological environment .In this study, Fuzhou was used as the background city .With the start of a brief analysis of typhoon which affects Fuzhou and causes disasters .Then we used MATLAB to predict and analyze the size of the rainfall ,and gain the intensity of the surface water-holding capacity .Meanwhile , raster data and hydrological analysis were also carried on , determine the submerged area . Finally, with the analysis of rainfall data ,to realize the flooded state and the surrounding scene simulation . |
