| Abstract: | The negative effect of microrelief upon runoff yield, explained by the increase in water storage and the slowdown in flow velocity, is a known phenomenon. However, research concerning surface roughness hitherto focused on decimeter- or centimeter-scale microrelief. Owing to the heterogeneous character of many natural plots, the effect of centimeter-scale microrelief was mainly shown under controlled sprinkling experiments, whereas no data was yet made available concerning the possible effect of a millimeter-scale microrelief upon runoff yield under natural field conditions. |
