Analysis of Guojuanyan Debris Flow Formation and Kinetic Parameters in Hongkou Village, Dujiangyan of Sichuan Province Post Earthquake

Guojuanyan gully, which lies in the center of earthquake-stricken area Dujiangyan city, is a viscous debris flow gully post Wenchuan strong earthquake. This paper made a deep analysis of the debris flow formation condition on the base of Guojuanyan valley and debris flow characteristics firstly, then conducted a calculation on the debris flow kinetic parameters, last parsed the development tendency of the Guojuanyan gully in the future and posed prevention measures based on its dangerous and objects which need to protect.
