  • their spatial and temporal distribution as well as the magnitude of the vertical and horizontal ground displacements. After field validation of the detected movements, they finally discuss their controlling factors. While most movements were triggered by intense
  • rainfall, their spatial and temporal distribution is strongly related with the nature of the vegetation cover and the human activity.
  • The impact of environmental change on the intensity and spatial pattern of water erosion in a semi-arid mountainous Andean environment

  • 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
  • Sediment yield variability in Spain : a quantitative and semiqualitative analysis using reservoir sedimentation rates
  • The objectives of this study are to analyse the spatial variability in area-specific sediment yield (SSY) for catchments in Spain and to understand the major factors controlling this variability. An attempt to explain the remaining variability

  • 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
