Compilation of Flood Inundation Map for Small and Medium Rivers in Hilly Areas of Shandong Province Based on ArcGIS and Mike
Taking Huanglei River in Shandong Province as an example,the measured river data was embedded into regional digital elevation model(DEM)by ArcGIS,and the one-dimensional and planar two-dimensional model of the river channel was established with Mike11 and Mike21 respectively,and the two-dimensional model was coupled and connected with MikeFlood.Mike software was used to calculate and analyze the designed flood surface line and flood inundation range data of the river course,and ArcGIS was used to build an elevation model within the inundation range.Finally,the inundation information at different frequencies was obtained through raster calculation with the ground elevation model of the study area,and the inundation objects were counted by combining the high-resolution satellite image map.
