Rainfall simulators are widely used yet there is little evidence in the literature to show that their spatial and temporal variability has been adequately taken into account. A first aim of this paper is therefore to examine this variability
, and to appraise methodologies by which it may be quantified. A second aim is to evaluate the implications for spatially explicit rainfall simulation experiments.

This paper presents a rainfall simulation experiment carried out on three 50 m2 plots in the Senegalese groundnut belt. The results indicate that the carrying capacity of the runoff at the scale of 10 m2, on gentle slopes ploughed perpendicular
The primary objectives of this initial study were to prepare sediment budgets for rill networks developed on a natural soil under simulated rainfall in a laboratory flume (University of Toronto, Scarborough), and identify the effect of confluences
