Study of avalanche models using well balanced finite volume schemes
Abstract:
Avalanches are natural disasters that have a significant human and economic impact on a global scale. Chile is a mountainous country and is significantly affected by these events. In this research, we are interested in using a numerical technique based on a well-balanced Finite Volume method to examine snow avalanche behaviour. As an avalanche model, we investigate the Saint-Venant system with Voellmy-Salm friction. We analyze the finite volume approach using a hydrostatic reconstruction scheme. The Rigopiano avalanche in Italy was used to test this strategy. The numerical model is explained and the results for the real avalanche case are presented graphically. Finally, some conclusions and suggestions for further research are presented.
