Description :
This study analyses the between-catchment variability of rill volumes produced by concentrated flow erosion during winter in the northern part of the Paris Basin. The working hypotheses were that 1) runoff concentrates along channels determined by topography or by agricultural practices; 2) rill length is a major component of rill volume variability on a catchment scale; 3) rill cross-sectional areas are controlled by the size of upslope runoff-contributing areas connected to the corresponding channels. Catchment erosion rates were estimated by adding together the predicted rill volumes for each segment within the catchment.
