AbstractErosion associated with concentrated flow in Mediterranean cultivated areas is considered as a major process of land degradation. In this work, the features of rills and ephemeral gullies generated in an olive orchard catchment of [.C ha, where tillage operations were usually applied, were measured and compared with sediment loads at the catchment outlet. The specific objectives were: ) to quantify the rills and ephemeral gullies measured in the catchment for inter-tillage periods where different hydrological features (precipitation and erosivity) and management schemes were observed; and O) to assess the contribution of concentrated flow to measured sediment discharge at the catchment outlet by considering the impact of cover crop strips during the last period.
