Abstract

The aim of this study was to measure under natural rainfall conditions the effects of 3 shrub covers (Colutea arborescens, Dorycnium pentaphyllum and Medicago strasseri) on runoff and soil loss. Plots were created and runoff discharge and sediment concentrations were measured after each rainfall event for 2.5 years (establishment period) and for the following 4 years when the shrubs were well-developed. The results of this experiment were compared with those of a previous study, in which the same data were recorded under conditions of simulated high-intensity rainfall in small plots. The effects of the shrubs at mitigating soil and water losses were more pronounced following high intensity rainfall events. Compared to smaller plots, the plots tested here showed similar soil losses under high intensity thunderstorms but runoff losses were much lower, suggesting that some of the runoff reinfiltrates the slope due to shrub distribution effects
