Avalanche Parameters: Dependence on the Size of the Granular Packing

The influence of the granular packing length on the avalanche parameters, such as its mass and the critical angles at which it begins and stops, is studied for packings of mono size glass beads under a controlled humidity environment. In order to understand the dynamics of this kind of systems, experiments are performed in boxes of two different dimensions to see the influence on the parameters. For both boxes, the critical angles show the same qualitative behavior. While the number of layers involved in the avalanche are determined by the box dimensions.
