The occurrence of debris flows in this catchment directly threatens the safety of the local people.Study on the dynamic character and its hazard assessment are the necessary prerequisite for the control schemes of debris flow and the safety function of the engineering.In terms of the characteristic of debris flow and the forming condition analysis,it was highly possible that debris in this catchment would occur once more;based on the field investigation data of Chuzanmozi catchment,the dynamic parameters were calculated,the risk of debris flow was evaluated by using the selection of 14 evaluation factors calculated by using AHP,results indicated that the risk degree of debris flows in the cathcment was 65.75,belonging to highly hazardousness,which could provide basis data for debris flow mitigation in Chuzanmozigou catchment.
