Dynamics Features of the Debris flow in Xiangtanlu Gully in Lianghe Country of Xiaojing County

The debris flow occurred in Xianglutan gully was a typical gully debris flow,which was located in Aba Tibetan Autonomous Prefecture in Sichuan Province.According to the basic features of the valley system and the debris flow,the paper at first discusses the formation conditions of the debris flow,like topography,water source and sediment source,then calculates the dynamic parameters,including bulk density,flow rate,flow capacity and sediment flush-out.Finally,proposes the appropriate prevention suggestion for the debris flow.
