Abstract

The boundary,streams and sub-watersheds were identified and the streams traits were analyzed based on high resolution digital elevation model(DEM) and Arc hydro tools of ARCGIS in Wuqiaohe watershed,Wanzhou county,Chongqing.Results indicated that the values of stream structure parameters were in the range of ordinary streams and Horton law played an important role.The streams of the river network were more developed in number than in length and there existed significant relationship of dissimilar area between stream structure and its function in Wuqiaohe watershed.The generated streams were completely accordant with actual streams and were uninterrupted based on high resolution DEM and Arc hydro tools of ARCGIS in Wuqiaohe watershed.So,it was a feasible method for watershed hydrology analysis.
