Description :
Measurement of soil splash erosion on an event-based scale under natural rainfall was carried out on a field spot. Kinetic energy of precipitation was calculated according to a model that incorporates horizontal terminal velocities of raindrops induced by wind speed. A digital raingauge with a high output resolution was used to measure precipitation. Erositivity indexes were worked out based on the assumption that those minutes with the highest energy input in an event are decisive for soil detachment.
