Abstract

Rainfall experiments have been conducted in laboratory in order to assess the hydrological of top soils very susceptible to surface sealing and containing rock fragments in different positions with respect to the soil surface. For a given cover level, rock fragment position in the top soil has an ambivalent effect on water intake and runoff generation. The effects of rock fragment position on infiltration rate and runoff generation are proportional to cover percentage. A simple model, based on the proportions of bare soil surface, soil surface occupied by embedded rock fragments, and soil surface covered with rock fragments resting on the soil surface, describes the runoff coefficient data relatively well
