The run-off and sediment yield were measured in steeply slopes covered with inert protection or vegetal species in two slopes gradients. The study was carried out in Maipú (Santiago) after the subsoil extraction of Rinconada de Lo Vial series (Typic Xerochrepts), a sandy loam soil from Central Chile. Covers of sea fig (Carpobrotus sp.) (T1), maize stubble (T2) and coarse gravel (T3) were evaluated using a control with spontaneous vegetation (T0). The treatments were established in two slope gradients (1:2.25 and 1:1.00, respectively) with three replicates. Precipitations were simulated by sprinkle irrigation, with rainfall intensities between 1.43 and 1.87 mm h-1, evaluating the run-off (%) and the mass of eroded sediments.
