The AA. present a spatially distributed model for the calculation of sediment delivery to river channels (SEDEM : SEdiment DElivery Model) at a catchment scale (100 to 10 000 km2). The model was applied on several catchments in central Belgium
Belgique ; Erosion des sols ; Expérimentation ; Granulométrie ; Modèle ; Pente de versant ; Ruissellement ; Transport sédimentaire
Belgium ; Experimentation ; Grain size distribution ; Model ; Rill wash ; Sediment transport ; Slope gradient ; Soil erosion
specifically, the study investigates to what extent sediment deposition (both total mass and sediment quality) can be predicted using the simple theory for flows with a shear stress below the threshold value, and which modelling approach can best be used once
