Dynamics Features and Hazard of the Debris Flow in Sewanzu Gully in Heishui County of Sichuan Province

Article Preview

Abstract:

The debris flow in Sewanzu gully was located in Heishui county of Sichuan province, which was 5.12 Wenchuan of sichuan earthquake severely disaster. It was large and very likely outbreak, which not only had posed a serious threat to the lives and properties of people, but also affected the reconstruction work going on smoothly. According to the basic features of the valley and the debris flow, the dynamic parameters,such as bulk density,flow rate,flow capacity and sediment flush-out were calculated.And then the hazard of the debris flow was evaluated quantitatively. The results could provide the basis for the governance and disaster prevention and mitigation of the debris flow gully.
