Sand dripping on an inclined plane

The system is simple to be prepared but much more difficult to be understood in its complexity: At the beginning of the process, individual grain motion prevails (individual trajectories of the bouncing grains can be recognized), later collective grain motion is dominant (sand mounds, avalanches, waves) – "Does the sand mound shape depend on the base position?"
