Criteria of erosion for cohesive soils

This paper focus on three types of erosion: the suffusion, the backward erosion, and the piping erosion processes. A new triaxial device to quantifying suffusion and backward erosion, and a new model for interpreting the Hole Erosion Test, are presented. It is recommended to use these erosion tests in order to evaluate the erosion parameters on any sample of cohesive soil from a site.
