  • will have the same causal factors as the landslides initiated in the past. Significant model results were obtained, with pre-landslide hillslope gradient and 3 different clayey lithologies being important predictor variables. Receiver Operating
  • Aerial photography ; Andes ; Ecuador ; Gully erosion ; Land use ; Model ; Mountain ; Semi-arid area ; Soil erosion ; Spatial analysis ; Water erosion
  • This paper describes the impact of land use changes on geomorphologic activity in the Andes Mountains in Ecuador. More specifically, it aims to identify the major factors controlling land use change on a decadal time scale, and assess the effects
  • 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
  • Ephemeral gullies. A spatial and temporal analysis of their characteristics, importance and prediction
  • Aggregate ; Grain size distribution ; Methodology ; Sedimentology ; Soil ; Soil properties ; X-ray diffraction analysis
  • Belgium ; Flanders ; Leuven ; Model ; Regression analysis ; Sediment budget ; Sedimentation rate ; Soil erosion ; Spatial scale ; Suspended load ; Watershed
  • Agricultural practice ; Belgium ; China ; Cultivated land ; Erosion budget ; Erosion rate ; Gully erosion ; Isotope analysis ; Loess ; Model ; Plateau ; Shaanxi ; Slope ; Soil erosion ; Water erosion
  • 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
