Abstract: An experimental investigation is carried out concerning the effects of engineering parameters on fine soil erosion. The chosen parameters characterize the density and the saturation of the soil. The influence on erosion resistance of energy, density, water content at compaction, and presence of a saturation stage or not are investigated. The soil erosion behavior is evaluated with a Jet Erosion Test device. The interpretation of the performed data is made according to a linear relationship between an excess hydraulic shear stress and the rate of erosion. The effects of the compaction and of the saturation are indicated by the observed variation of the erosion law parameters. The results underline the effects of the soil fabric and the saturation on the soil erodibility.
