| Abstract: | Wangjiashan Gully is located in Xiaojin County of Sichuan Province.The debris flow of Wangjiashan Gully is the most representative,which has been long endangering the County＇s safety.The gully covers the basin area of 8.02 km2,stream length of 5.14 km,the relative height of 1614 m,and the channel gradient of 314.0‰.Loose solid material in the gully comes from 10 landslides inside;as a result,it is very easy to form the debris flow.The debris flow usually occurs for heavy rainfall of short duration.Some measures have been taken such as blocking dam,bulwark and biological measures. |
