A new Method to identify Surface-waters From DEM

摘要：

DEM is the digital expression of the topographic landscape properties. DEM is commonly used in watershed hydrological simulation for delineating drainage networks. A new method to identify surfacewaters from DEM is presented, which compares the area threshold, the elevation difference threshold and potential outlet, respectively. At the last, this method is applied to experimental region lies in Tibet Autonomous Region. As the results, the identifying method is made by the paper can accurately identify most surface-waters.
