  • Sediment yield variability in Spain : a quantitative and semiqualitative analysis using reservoir sedimentation rates
  • Forecast ; Gully erosion ; Model ; Reservoir ; Sedimentation rate ; Soil erosion ; Spain ; Watershed
  • 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
  • Gully-head morphology and implications for gully development on abandoned fields in a semi-arid environment, Sierra de Gata, southeast Spain
  • Almería ; Gully erosion ; Land use ; Semi-arid area ; Slope ; Slope gradient ; Soil conservation ; Soil erosion ; Spain ; Wasteland ; Water erosion
  • Relative efficiency of three representative matorral species in reducing water erosion at the microscale in a semi-arid climate (Valencia, Spain)

  • In this study, short-term headcut retreat was monitored from 46 active bank gullies, selected in the Guadalentin and the Guadix basin in Southeast Spain, over two years. The AA. investigate the relationship between annual gully head retreat rate

  • of ephemeral gully initiation in intensively cultivated Mediterranean environments. Two relatively homogeneous study areas in Southeast Spain and Northeast Portugal with widespread ephemeral gullying were selected.
  • Andalusia ; Arid area ; Desertification ; Gully erosion ; Lithology ; Mediterranean area ; Rill wash ; Sediment transport ; Soil erosion ; Spain ; Water use ; Watershed
  • The AA. examine the factors that control the spatial distribution of bank gully heads along a reach of an ephemeral river (Rambla Salada) in an area threatened by desertification in Southeast Spain. The activity of 458 gully heads was assessed
  • Arid area ; Dendrochronology ; Dendrology ; Erosion rate ; Gully erosion ; Murcia ; Rill wash ; Soil erosion ; Spain ; Watershed
  • The aims of this paper are : 1) to develop a methodology based on dendrochronology to estimate gully erosion rates; 2) to apply this method to gully sites selected in the Guadalentin basin in southeast Spain. The method is developed for Pinus

  • An EGEM-input data set for 86 ephemeral gullies was collected : detailed measurements of 46 ephemeral gullies were made in intensively cultivated land in southeast Spain (Guadalentin study area) and another 40 ephemeral gullies were measured in both
  • Almería ; Experiment plot ; Grain size distribution ; Lithology ; Precipitation ; Rill wash ; Roughness ; Semi-arid area ; Slope ; Soil erosion ; Soil moisture ; Spain
  • moisture content was studied during rainfall in the laboratory. In order to evaluate the long-term effects of rainfall and sheet erosion on surface roughness of stony interrills, two abandoned hillslopes in southeastern Spain were investigated. Relations

  • 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
