Soil erosion: The influence of compaction curve - Application on Silt soil using the Jet Erosion Test

Abstract

     The influence of some soil parameters on the erosion of a silty soil, characterized by the erosion coefficient kD, the critical shear stress τc, and the equilibrium erosion depth Pe, is studied. A series of test using the submerged Jet Erosion Tests was carried out to examine the influence of dry density ρd, compaction water content w. The results show that at dry side of compaction curve the erosion coefficient and the equilibrium erosion depth decrease when the dry density, the compaction water content, whereas the critical shear stress increases with these parameters. But an inverse relationship is observed at wet side of compaction curve.
