Debris Flow Source Evolution Law and Hazard Assessment of Gangou in Hongse Village
The debris flow source in strong earthquake area has the characteristics of evolution, which leads to the change of the hazard of debris flow. The debris flow of Gangou in Hongse village is a typical representative of debris flow in strong earthquake area. Multi-period remote sensing image interpretation and on-site investigation were used to find out the evolution law of debris flow source. Based on the understanding of the law of debris flow source evolution, the numerical simulation method was used to evaluate the debris flow hazard, and the result of debris flow hazard evaluation of Gangou in Hongse village is obtained. In this study, a debris flow haz-ard assessment method based on source evolution was established to provide a scientific reference for accurate evaluation of debris flow hazard in strong earthquake areas.
