Description :
The main aim of this study was to develop an approach to predict soil detachment by rill flow in the presence of freshly incorporated vegetation residue that is compatible with current understanding of rill hydraulics and requires no additional information on rill geometry. Laboratory experiments were carried out. The data are presented and analyzed. An approach to calculate the erosivity of rill flow on surfaces with fresh vegetation residue is proposed. Finally, this new procedure is evaluated using field data collected in another study.
