| Abstract: | This paper deals with numerical simulation of debris flow inundation by applying mathematical model of the two-dimensional unsteady flow equations. The theory and methodology of evaluations on risk degree of de.bris flow were put forward.The example application and test show that this model is easily calculated and has a good stability and accuracy. It is a new method to evaluate risk degree of debris flow ondepositional fans. |
