The objective of this investigation was to estimate event soilloss per unit area from bare plots in central and southern Italy using an empiricalmodel for sedimentconcentration. The analysis was developed using data collected on bare plots differing in length (11â¿¿44 m) and slope (10â¿¿26%) at three Italian stations (Masse, Umbria; Caratozzolo, Calabria; Sparacia, Sicily). At first, an analysis was carried out, using the experimental data collected at Sparacia, to establish a relationship between sedimentconcentration and hydrological variables, such as runoff, rainfall amount and single storm erosion index. Then, an empiricalmodel to estimate plot soilloss as a function of rainfall amount, single storm erosion index, runoff amount, and slope length was developed. Finally, using the complete data set (Masse, Caratozzolo, Sparacia), the model was extended to include soil erodibility and slope steepness effects on plot soilloss.
