Numerical methods for geophysical yield stress fluid flows

Abstract

We consider a prototype of a 2D Shallow Water Bingham model. We present a 2D well-balanced FV scheme coupled to duality methods which is able to compute accurately the arrested states of avalanches. To illustrate the ability of these schemes to handle the numerical difficulties encountered in geophysical applications (complex DEM topographies, long space domains and long time scales), we present in particular a simulation of an avalanche in the Taconnaz path (Chamonix, Mont-Blanc).
