Abstract

In order to understand the evolution of hydrodynamics and detachment soil rate with different stages of degradation of a rangeland by overstocking, two rainfall simulations were conducted on 1 m2 experimental plots in an abandoned cultivated South African terrace showing progressive stages of vegetal degradation, from total grass soil cover to completely bare surfaces. The main objective was to evaluate the impact of grass cover on soil infiltration by water and sheet erosion. A second objective was to relate soil erosion to other environmental factors including soil surface features and top-soil physical and chemical characteristics
