Abstract

Including runoff in USLE-type empirical models is expected to improve plot soil loss prediction at the event temporal scale. The goal of this paper was to develop an estimating procedure of event soil loss from bare plots at 2 Italian sites, i.e. Masse, in Umbria, and Sparacia, in Sicily, having a similar sand content but different silt and clay contents. A test of alternative erosivity indices for the Masse station showed that the best performances were obtained by the USLE-MM, originally developed at the Sparacia station. It is concluded that runoff is an important predictor of soil erosion, and local soil characteristics have a more noticeable effect on soil loss for events with a relatively low soil detachment and transport ability. A wider applicability of the USLE-MM scheme can be suggested than for the Sparacia station alone
