Review Study on the Risk Assessment of Debris Flow

Abstract

Debris flow is a common geological disaster, with the characteristics of outbreak suddenly, ferocious, quickly, which is a serious threat to the mountainous area traffic, water conservancy and hydropower, mining and other engineering facilities and life property safety of local residents. The debris flow disaster research mainly concentrated in the debris flow disaster risk assessment, and there is less research on vulnerability assessment of hazard-affected bodies, so it is need to make a further study on debris flow vulnerability evaluation and the risk assessment of debris flow, which will be helpful for the forecast of debris flow disaster, and early warning and prevention work.
