ABSTRACT A small interrill rainfall simulator was used to evaluate the effects of rainfall intensity, soil strength and slope on interrill erosion. There was no interaction effect of slope on the exponent of the intensity term in an expression relating interrill detachment to rainfall intensity. Interrill soil erodibility was closely related to soil shear strength after rainfall, as measured by a vane shear device. Interrill soil erosion was well estimated by a prediction equation that included rainfall intensity, slope and soil shear strength.
