Upwinded finite difference schemes for dense snow avalanche modeling. (English) Zbl 0974.76058
From the summary: One-dimensional dense snow avalanche equations are numerically solved using conservative variables and stable upwinded total variation diminishing finite difference schemes. The numerical model is applied to simulate avalanche motion in general terrain. The proposed discretization schemes do not use artificial damping, an important requirement for the application of numerical models in practice. The simulation of both laboratory experiments and a field case study are presented to demonstrate the discretization schemes.
