Description :
In this paper the physical model concept developed in USA was tested by using soil loss data collected on plots of different length at the experimental station of Sparacia, in Sicily (South Italy). This investigation supported the conclusions that i) a coefficient of determination between measured and predicted soil loss values of 0.77 has to be considered as the best-case prediction scenario and ii) an uncalibrated deterministic erosion model would not give more accurate results than those obtained by a replicated plot measurement. This calculation is useful since it allows to quantitatively establish the maximum gap that has to be covered by an alternative simulation model to obtain the realistically best estimate of plot soil loss at the event temporal scale.
