Granular flow trapped on an incline: dynamics of the sandpile

Experimental results have been recently reported for the dynamics of two-dimensional sand fronts formed by the trapping of a flow running down an inclined plane. We explain the scaling law observed for the front profiles and give their analytic expression using a simple phenomonelogical model for in...

Summary:Experimental results have been recently reported for the dynamics of two-dimensional sand fronts formed by the trapping of a flow running down an inclined plane. We explain the scaling law observed for the front profiles and give their analytic expression using a simple phenomonelogical model for interfacial shapes and interfacial flows of granular materials.
