  • Field investigation on rilling in the experimental Sparacia area, South Italy
  • Erodibility ; Erosion rate ; Experimental catchment ; Italy ; Model ; Rill wash ; Semi-arid area ; Sicilia ; Soil erosion ; Water erosion ; Watershed
  • The measurements were made on a plot 6 m wide and 22 m long subjected to natural rainfalls in the experimental Sparacia area located in western Sicily. First the contribution of each component (rill and interrill erosion) to total soil loss
  • was established. Then the analysis allowed establishment of a power relationship between the rill length and the rill volume. Finally, for 3 events detailed information on rill erosion and rill morphology allowed verification of the applicability of WEPP
  • and estimation of the rill erodibility constant.

  • Effects of freshly incorporated straw residue on rill erosion and hydraulics
  • Agricultural practice ; Agropedology ; Belgium ; Erosion control ; Erosion rate ; Experimentation ; Rill wash ; Soil erosion ; Soil properties ; Vegetation ; Water erosion
  • The main aim of this study was to develop an approach to predict soil detachment by rill flow in the presence of freshly incorporated vegetation residue that is compatible with current understanding of rill hydraulics and requires no additional
  • information on rill geometry. Laboratory experiments were carried out. The data are presented and analyzed. An approach to calculate the erosivity of rill flow on surfaces with fresh vegetation residue is proposed. Finally, this new procedure is evaluated

  • The measurement and modelling of rill erosion at angle of repose slopes in mine spoil
  • Australia ; Digital elevation model ; Gully erosion ; Mine ; Model ; New South Wales ; Rehabilitation ; Rill wash ; Simulation ; Slope ; Soil erosion
  • This study examines the ability of a terrestrial laser scanner to quantify rills that have developed on fresh and homogeneous mine spoil on an angle of repose slope. It also examines the ability of the SIBERIA erosion model to simulate the rill's
  • spatial and temporal behaviour. Results show that while the overall hillslope morphology was captured by the laser scanner, with the morphology of the rills being broadly captured, the characteristics of the rills were not well defined. These results
  • demonstrate that an even greater density of points is needed to capture sufficient rill morphology. Nevertheless, SIBERIA simulations of the hillslope demonstrated that the model was able to capture rill behaviour in both space and time when correct model

  • This study makes a multi-scale assessment over a time span of 30 years of environmental rehabilitation in one of the world's most degraded areas : the Tigray highlands. It study shows that in Tigray sheet and rill erosion rates have decreased
