IMO this type of erosion is mainly caused by the changing temperatures
destroying the structure of the material at the surface.  Of course water and
wind are major factors for transportation of material.

That's a good idea, it is only a problem how to define those areas.  

BTW, my code partly already does this, because it erodes more on steeper areas,
where there is normally fewer vegetation.
