Abstract

In the Wenchuan earthquake-affected area, the AA. analyzed the compound effects of simultaneous debris flow events, and proposed 3 quantitative methods of debris risk assessment based on kinetic energy, flow depth, and inundation depth. They established a method to determine the vulnerability of different hazard-affected objects, particularly concerning the susceptibility indexes of buildings or structures. By analyzing the elements underlying hazard formation conditions, damage potential, and the socio-economic conditions of mountain townships, they proposed a systematic and quantitative method for risk analysis of mountain townships. Finally, the proposed method was applied to a case study of Qingping Township, which was affected by 21 simultaneous debris flows triggered by a 50-year return period precipitation event. The proposed method analyzed the superposition and chain-reaction effects of disasters and divided the affected area of the township into 3 risk zones
