Stabilisation of runoff pathways
Pathways of concentrated surface runoff should be stabilised by permanent greening to prevent erosion. They can be reinforced by stones so that they are able to transfer the concentrated surface runoff without the occurrence of erosion on the pathway. The most common shape is a parabola with a low depth, which is most similar to that of the naturally created pathways. The measure requires an occupation of agricultural land. It should be implemented if protective soil measures are ineffective to protect soil from erosion. When accompanied by appropriate vegetation, they can be a part of the territorial system of ecological stability. The effect is enhanced when other measures exist in the contributing area. The consolidation of property rights relations might be necessary.
