The different states of a ball on a rough inclined plane are analyzed from experimental results and numerical simulations. The conditions of static equilibrium are given. The control parameters are the inclination angle of the plane and the surface roughness. Then, we propose a "phase diagram" for the motion of the ball. These results are expected to be useful in understanding the origin of the segregation effects on the surface of a sandpile.
