  • 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
  • for which medium-term sediment export measurements as well as spatially distributed data on topography, land use and soils are available.
  • The impact of environmental change on the intensity and spatial pattern of water erosion in a semi-arid mountainous Andean environment
  • Aerial photography ; Andes ; Ecuador ; Gully erosion ; Land use ; Model ; Mountain ; Semi-arid area ; Soil erosion ; Spatial analysis ; Water erosion
  • Analyse spatiale ; Andes ; Domaine semi-aride ; Equateur ; Erosion des sols ; Erosion hydrique ; Modèle ; Montagne ; Photographie aérienne ; Ravinement ; Utilisation du sol
  • of land use changes on the intensity and spatial pattern of water erosion using a spatial modelling approach.
  • Ephemeral gullies. A spatial and temporal analysis of their characteristics, importance and prediction
  • The influence of both process descriptions and runoff patterns on predictions from a spatially distributed soil erosion model
  • This study presents a sensitivity analysis of the soil erosion model LISEM, whereby not only the sensitivity to parameter values is considered, but attention is focused on the effects of process descriptions and the routing of overland flow
  • Grain-size analysis by laser diffractometry : comparison with the sieve-pipette method
  • Clay mineral ; Grain size distribution ; Methodology ; Soil ; Soil properties ; Soil science ; X-ray diffraction analysis
  • Results of a traditional sedimentation technique for grain-size analysis (the sieve-pipette method) were compared with those of a laser diffraction grain-size analyser, the Coulter LS-100. Milled quartz samples and silty soil samples were used
