Description :
The study was executed on 6 barren conical spoil heaps, which are excellent study objects to bring the slope aspect in relation with rill erosion. Three indicators for rill erosion (volume of rills, drainage density and mean distance of the head cut of the 5 uppermost rills till the top of the spoil heap) were associated with 4 explanatory factors (slope gradient, vegetation density, rock fragment cover and slope aspect). It is shown that the rill volumes on windward slopes are 3 times higher than on leeward slopes. The other explanatory factors showed little influence on the magnitude of rill erosion.
