Abstract

In order to predict a flow area of snow avalanche, a numerical method based on fluid dynamics has been proposed. In the CIP-based numerical method, snow is modeled as a Bingham fluid with the consideration of the Mohr-Coulomb failure criterion. Therefore, the cohesion c and the internal friction angle φ are the material parameters for the flowing medium. In this study, using the numerical method with THINC in CIP, the snow avalanche model tests were simulated. In the model tests, snow avalanches were reproduced in a low-temperature room. In the tests, snow flowed on a model slope and the travel length of snow was measured. The parameters used in the simulations are obtained from a previous research. In order to investigate the applicability of the numerical method proposed in this study, the results of model tests were compared with simulation results.
