  • Predicting event soil loss from bare plots at two Italian sites
  • 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
  • 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
  • An analysis of the statistical distribution of event soil loss was carried out using the data collected in the period 1999–2008 at the microplots and plots of the Sparacia experimental area (Sicily, Italy). In particular, the theoretical probability
  • The USLE scheme cannot be used at the Sparacia experimental area (near Palermo,Sicily) to predict event soil loss per unit plot area, Ae, because experimental data suggest that, generally, Ae does not increase with plot length, λ. The USLE-MM scheme
  • and interrill erosion measurements showed that sediment delivery processes occurred in some erosive events and that the rill erosion rate was dominant in many cases. The measurements were used for testing both the empirical relationships between the channel
  • calculated for a given event using all replicated data collected in plots having the same length. Then, a comparison between the frequency distribution of soil loss and rainfall erosivity index of the USLE was carried out. An estimating criterion
