摘要：The purpose of this paper is to reveal the pour point description of watershed based on Digital Elevation Model (DEM) is the precondition of research on building distributed hydrological model and hydrological simulation. This paper explicates the method of revealing pour point of watershed based on DEM. With the support of GIS( Geographical Information System) technique, boundary of watershed and drainage areas of sewer pipeline discharge into a area where a pump station could be installed in Bilaspur district so as to provide the easily flow of sewerage into a treatment plant or a river basin. Using a hydrology module in ArcGIS environmental, watersheds for Bilaspur were delineated. The result of this experiment indicates that this method can effectively solve the problem of parallel waterways and main channel which departs its natural position. In flat area, mountain area and terrain area this method can reveal pour point using watershed analysis.
