| Abstract: | Beginning with the introduction of the digital elevation model(DEM) to extract hydrological characteristics,we simulated and analyzed hydrological characteristics of Sushui river drainage area,Yuncheng city,Shanxi province by using Arc Hydro Tools extension module and SRTM DEM data model.It conducted the simulation and analysis of the surface hydrological characteristics of drainage area,and extracted the hydrological information of the Sushui river drainage network and drainage basin.Our current study provides evidences for the further investigation of the environmental evolvement,vegetation growth and land coverage in the drainage area of Sushui river. |
