International audience. Soil redistribution within the landscape is increasingly investigated because it modifies local soil properties and is a major process of soil degradation in agro-ecosystems. Hedgerow networks in the landscape are adapted human-made objects that can be used to study soil redistribution processes within the landscape while water erosion redistributes soil, as hedges act as barriers to the physical transfers of soil particles. The aims of this study were to use pedological knowledge on soil-landscape evolution to simulate quantitatively the effect of human-made landscape structures on soil redistribution at fine spatial and temporal scales.
