The performance of stone cover on infiltration, runoff, erosion and sediment yield during overland flow were quantified using a hydraulic tilting flume under two different discharges with four different slopes (0.1, 1.0, 3.0, and 5%). Two surface conditions were tested: bare soil and partial stone-cover (50%) arranged in two strips. Stone cover reduced flow velocity, decreased outflow, increased infiltration and reduced soil erosion compared to bare soil. Stone cover was most effective at reducing discharge when the flow depth was less than the median particle diameter, but was effective at reducing sediment yield for both flow depths. Stone cover prevented rill erosion above 3% slope. Infiltration decreased with increasing slope due to lower ponding depths on steeper slope. Sediment concentration increased with an increase in slope even with stone cover. In the case of bare soil, sediment concentration showed an exponential increase with increase in slope. Stone cover was effective in increasing infiltration rate of overland flow by decreasing flow velocity, but only when flow depth was less than or equal to median particle diameter. By contrast, stone cover reduced erosion and sediment load at both flow depths. Models of infiltration rate and sediment transport capacity were calibrated with the observed data for use in other modeling applications.
