Abstract

The AA. show that rainfall kinetic energy (and hence soil detachment) does not bear a simple relationship to intensity. For low-intensity rainfall, observed variations in drop-size distributions indicate that soil detachment, at a given rainfall intensity, may vary by about a factor of two. Comparable estimates of variation in soil detachment at high rainfall intensity are not possible because of a dearth of observational data on variation in drop-size distributions in high-intensity rainfall. Variation in drop-size distributions in natural rainfall may, therefore, account for a significant component of differences between observed soil detachment and that predicted by models of soil erosion
