Description :
This paper outlines some recent developments in modelling soil erosion processes, and their use as a template on experimental data in order to derive soil erodibility parameters of defined physical meaning. The paper first compares a theoretical model used to describe the result of armouring in stream beds with a model designed to describe, at equilibrium, the relationship between the size distribution of sediment in transport with the size distribution of the bed over which it flows. The significance of the formation of a layer or bed by sediment deposition, and the role of soil strength, is then investigated for two different erosive regimes.
