摘要
Abstract
The May 12th Wenchuan caused mass debris flows in Sichuan, earthquake the debris flows in size and feature are different from before. In order to analysis the characteristics of debris flows after the earthquake and explore the phenomenon,we take Wenjia Gully in the Mianyuan River Basin as the study subiect. DEM data got before and after disaster are compared on the ARC- GIS platform. In this paper,three aspects including the slope of the channel,the erosion depth,and the change of ideology and regional gully erosion are analyzed to find the erosion characteristics of Wenjia Dgully, and reveal the processes of erosion and deep groove phenomenon. It can provide some foundations for the hazards assessment and disaster control.关键词
