Abstract
Suffusion is the internal erosion process by which finer soil particles are detached from the solid matrix, and transported through constrictions by seepage flow. At the macroscopic scale, this is a bulk erosion process and corresponds to a source term in the mass balance equations. This paper constitutes a step towards bridging the gap between the counter intuitive bulk erosion model and our intuition that erosion is essentially an interfacial process. We suggest that a framework within suffusion can be viewed as a clay/water interface erosion at the microsopic scale. The coefficient of surface erosion appears to be a relevant parameter for the suffusion bulk erosion law. The comparison between the results of the present modeling study and previously published experimental data supports the validity of our approach.
