Abstract
Arable sites, which are exposed to direct raindrop impact, slake and seal, which significantly reduces infiltrability. Application of the TOPSIM model in small rural catchment areas with diverse use patterns confirms the significant influence of vegetation cover on surface sealing and overland flow generation which leads to a land-use induced heterogeneity in runoff generation. Runoff sites close to the outlet, significantly influence the overall discharge of the drainage basin. Runoff from peripheral areas of the basin may be decelerated while flowing over less-sealed and more permeable areas resulting from a more complete soil cover. Surface runoff from a basin can thus be reduced effectively by a soil management plan aimed at maintaining a soil cover throughout the year and by more diversified land use.
