Abstract

This study simulated an actual snow avalanche that took place in 2011. A numerical method based on computational fluid dynamics was used to simulate the avalanche. In the simulation, snow was assumed to be a Bingham fluid; the shear strength of the Bingham fluid was described using Coulomb's failure criterion. Before conducting numerical simulations of the avalanche, laboratory experiments were conducted to confirm that the Bingham fluid model accurately represents the behavior of snow. Then, the numerical framework was used to simulate the actual avalanche. The simulation results demonstrated that the numerical framework can predict the flow behavior of a snow avalanche. The effectiveness of a retaining wall as an avalanche countermeasure was also evaluated in simulations.
