  • Channel width-flow discharge relationships for rills and gullies
  • Belgium ; Discharge ; Europe ; Gully erosion ; Italy ; Land use ; Rill wash ; Runoff ; Slope ; Soil erosion ; Spain ; Water erosion
  • In order to investigate the width-discharge relationships for rills and gullies, a new method is proposed based on field measurements of widths of concentrated-flow erosion channels both upstream and downstream of channel junctions. A total of 322
  • rill and gully channel junctions with various soils and land use types were investigated in Belgium, Italy and Spain. The obtained data confirmed the existence of the power relationship for rills and gullies, with the exponent varying from 0.43
  • for small rills to 0.5 for gullies.

  • , these results are compared with the findings obtained from rills, discontinuous gullies and gullying by landslide scarring.
  • Effects of land use and land cover on sheet and rill erosion rates in the Tigray highlands, Ethiopia

  • 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
