Focus on a project

Granular avalanches in the presence of obstacles

Y. Bertho, B. Darbois Texier, P. Gondret
Collaborations: J. Benito, I. Ippolito

We experimentally study the influence of a forest of obstacles on the avalanche process of a layer of grains on an inclined plane. A model taking into account the resistance of the pillars on the movement of the grains makes it possible to predict the decrease in flow observed experimentally. This work is a first step for the dimensioning of devices for preventing the risks associated with snow avalanches or rock slides, for example.
