Geomorphology of the
In order to study the geomorphologic asymmetric characteristics of Taohe River drainage basin and discuss the evolution of the Taohe River and the reason of the stream direction sharply changing at Minxian County, a DEM based topographic analysis of mountain belts has been done to extract much drainage and sub-basin information and the drainage geomorphic parameters of the Taohe River. The structural implications of the geomorphologic asymmetric characteristics of the
