Abstract:From digital Elevation model(DEM Elevation Digit) directly extract river network and Watershed information,is based on the development and application of hydrological model.Using the hydrologic analysis tool in ArcGIS extract hydrologic characteristics form DEM.Mainly including DEM pretreatment,the direction of flow determine,extraction of flow Accumulation,river network,watersheds and watershed division.The article discusses two different methods of watershed division,provide the reference for Watershed division and Hydrological analysis.
Keywords:DEM  watershed  river network and hydrologic analysis
