[automatically translated] Many process-oriented models for rill erosion prediction using parameters such as the rill erodibility, which are specific to the site of interest, and therefore the application of these models require the measurement of these parameters or their indirect estimation. The aim of this paper is to propose a method for indirect measurement dell'erodibilità rill of the experimental area soil Sparacia, in Sicily. They were used the measurements conducted on rill detected in parcels Sparacia at seven natural rainfall events and a simple mathematical approach based on the equation that simulates the posting of sediments taking into account the variability over time of the variables that are displayed. The proposed method, the application of which requires only the knowledge of the geometrical characteristics of rill the end of the event and the duration of the event, provides an approximate value dell'erodibilità rill as it is based on simplifying assumptions. On the other hand the measurement dell'erodibilità rill in the field is more realistic, but also more complex, than that which can be obtained with laboratory investigations and the proposed method has the advantage of simplifying the field of measurement.
