| Abstract: | Based on the principle of momentum conservation and conservation of mass, this paper studies and sets up a mathematical model of the process of debris flow deposit and work out the model with numerical simulation method. Meanwhile, the paper analyzes and appraises scope and extent of danger caused by debris flow, and carries out an assessment of losses by debris flow disaster with Shengou flume in Dongchuan City, Yunan Province as an example. |
