摘要
选取威海母猪河流域作为研究区域,依据该流域1961—1965年洪水过程为基础资料,采用广义极值分布函数方法计算了流域不同重现期面雨量;采用Arc GIS法计算该流域重现期面雨量空间分布;使用Flood Area模型进行淹没模拟;采用GIS空间插值技术,叠加DEM数据,通过全面分析得到威海母猪河流域洪水风险区划。
Weihai sow river basin was selected as the research area. Based on the flood process of the basin from 1961 to 1965,the generalized extreme value distribution function method was used to calculate the area rainfall in different return periods.ArcGIS was used to calculate the spatial distribution of area rainfall in the return period of the basin, the flood area model was used for inundation simulation, GIS spatial interpolation technology was used, DEM data was superimposed, and the flood risk zoning of Weihai sow river basin was obtained through comprehensive analysis.
