  • Two-dimensional modelling of the within-field variation in rill and gully geometry and location related to topography
  • Agricultural practice ; Belgium ; Cultivated land ; Erosion rate ; Gully erosion ; Loess ; Model ; Rill wash ; Slope ; Slope gradient ; Soil erosion
  • This paper relates the within-field variation in rill erosion rate to topographic attributes and derives a predictive equation between rill erosion rate and topography in a two-dimensional context. The AA. also investigate whether it is possible
  • to delineate the areas prone to rill and ephemeral gully formation based on a topographic threshold condition, and investigate the extent to which the predictions can be improved by introducing the direction of cultivation into the model. To limit the effects

  • The role of vegetation in the retardation of rill erosion
  • China ; Deforestation ; Erosion rate ; Gully erosion ; Land use ; Plant cover ; Rill wash ; Sediment budget ; Slope ; Soil erosion ; Southern China ; Vegetation
  • Large rills with catchment areas pose serious soil erosion problems to South China, after deforestation has exposed the deeply weathered granitic slopes to the impacts of tropical rainstorms. The purpose of this study is to determine
  • the effectiveness of vegetation in controlling the erosion of large rills in South China.

  • Natural conditions and land use make the Myjava Hills particularly liable to geomorphic processes induced by surface runoff. The investigation of geomorphic effects focused on a detailed mapping of the spatial distribution of rills and soil loss

  • Biancane badlands consisting of small domes dissected by rills and micropipes, with rough disordered microrelief, can be found along the Apennines in Italy. This study was undertaken in a residual area of biancane in southeast Tuscany to identify
