Steep slope snow catching capacity
When modeling ground temperatures in steep slopes, there is the problem that too much snow is simulated on the slope. This is because in real slopes, some of the snow would fall off. A possibility to simulate this behavior would be to attribute a maximum catching capacity to the slope, for example depending on the roughness of the slope. Once this maximum capacity has been reached, all new snow coming would simply be discarded (of course, this should not be used in Alpine3D where the mass should instead be redistributed).
