Description :
The results of seven experimental runs show that the runoff erosion resistance of a loamy material is extremely sensitive to variations in initial moisture content and, to a somewhat lesser extent, in bulk density. The very low resistance to runoff erosion of initially dry material is explained by structural changes which take place at the time of wetting : slaking and microfissuration cause a considerable decrease of the soil's shear strength and therefore of its resistance to runoff erosion.
