Risk Assessment and Control Measure of Debris Flow in Chunyashu Gully of Seismic Disastrous Area of Sichuan Province

Chen, Ji-hua / Wu, Hui-Ge / Zhou, Hai-Hui / Zhang, Hai-Liang

The terrain of Chunyashu gully in Dujiangyan city of Sichuan province was steep, plenty of loose material increased after the Wenchuan earthquake. Debris flows were triggered in September 2008 and August 2009, and the debris flow was a serious threat to the highway and the residents. Risk of Chunyashu gully debris flow had been analyzed by the latest assessment method, and the result was that the risk degree of this gully was middle. Finally according to the local situation the control measure of interception dam and other advices had been suggested to protect the safety of the residents.
