Description

In this paper, in order to estimate the run-out distance of snow avalanche, its traveling path and spreading width are studied from view point of kinematics as well as dynamics. The influence range of the snow avalanche is discussed with a dynamic analysis of the snow avalanche on three-dimensional topography based on the model of Perla and others. A simplified simulation technique for the spread of the snow avalanche with an application of the analysis is proposed. Some numerical example are shown in the ski resort with a model topography.
