Abstract

The scaling properties of granular flows down an inclined plane are investigated in a model previously proposed to describe surface flows on a sandpile.  Introducing a depth dependant friction, we are able to reproduce the results obtained experimentally by [O.Pouliquen, Phys. Fluids 11, 542 and 1956 (1999)] on both the fronts velocities and their shapes.
