Estimating Soil Detachment Caused by Raindrop Impact

ABSTRACT THE statistical performance of several soil detachment relations was evaluated using data available from the literature. The rainfall parameter which provided the best statistical fit was found to be kinetic energy times unit of drop circumference. This realtionship incorporates both raindrop diameter and velocity as variables. For the case of raindrops falling at terminal velocity, impact velocity was written as a function of raindrop diameter and, therefore, eliminated in the detachment equation. From information available in the literature on the drop size distribution of natural rainfall at varying rainfall intensities, an equation relating soil detachment to rainfall intensity was obtained.
