Description :
The aggregate size distribution is a recognized factor influencing crust characteristics and transport during interrill erosion events. This parameter was used in this work in order to improve the understanding of the relationship between aggregate stability and erodibility. A second aspect of this study was to investigate the size selectivity of interrill erosion processes : breakdown, detachmant by splash and transport by overland flow. This experimental work was based on rainfall simulation and aggregate stability tests which were performed using 2 different soils : a clay loam slightly sensitive to erosion, and a more susceptible silt loam.
