  • The AA. develop an approach to the determination of erosion rates that is based upon the entrainment rates and travel distances of individual particles. Parameterization of the equations to take account of such factors as gradient and sediment
  • supply is required to proceed from the conceptual framework to quantitative measurements of erosion. However, this conceptual model solves the apparent paradox of the sediment delivery ratio, resolves recent discussion about the validity of erosion rates
  • made using USLE erosion plots, and potentially can reconcile erosion rates with known lifespans of continents.

  • Soil erosion is an important environmental problem in Loess Plateau. The soil erosion processes may be divided into three types : water erosion, gravitational erosion, wind erosion. The energy of erosion action depends upon the rainfall
  • and topography, but erodibility depends upon the vegetation and soil properties. The degree of soil erosion in the Loess Plateau changes with variations of interaction of erosion and anti-erosion measures.

  • Gully erosion ; Hungary ; Research in progress ; Sediment transport ; Soil erosion ; Water erosion ; Watershed
  • Soil erosion has become very important over the last decades. The role of gully erosion has been recognized only lately. Gully erosion plays a decisive role in the redistribution of eroded soil on a slope and in delivering it to watercourses
  • . In the paper the classification and description of soil erosion processes and an analysis of the physico-geographical conditions of gully development were given and the main fields of gully erosion research in Hungary were presented. - (AM)

  • Bank erosion ; England ; Flood ; Fluvial erosion ; Fluvial processes ; Freeze-thaw cycle ; Global change ; Meteorology ; Spatial variation ; Stream ; United Kingdom ; Warwickshire
  • The aim of this paper is to demonstrate that subaerial processes may be underestimated as an erosive agent, and process dominance has a temporal, as well as spatial, aspect. Bank erosion on the River Arrow was monitored for 16 months (December 1996
  • to March 1998) using erosion pins. Variations in the rate and aerial extent of erosion are considered with reference to meteorological data. Throughout the first 15 months all erosion recorded was subaerial. While the role of subaerial process
  • as preparatory is not contended, it is suggested that such processes can also be erosive.
A conceptual model of wind erosion of soil surfaces by saltating particles
  • A conceptual model of wind erosion of soil surfaces by saltating particles
  • Energie d'impact ; Eolien ; Erosion des sols ; Erosion éolienne ; Expérimentation ; Modèle ; Royaume-Uni ; Saltation ; Vent ; Vitesse d'érosion
  • Aeolian features ; Erosion rate ; Experimentation ; Model ; Soil erosion ; United Kingdom ; Wind ; Wind erosion
  • This paper presents a conceptual model of wind erosion by saltating grains in which the erosion rate is determined by the strength of the surface and the energy delivered to the surface by the saltating grains. Methods are presented
  • for the measurement of both distributions and consequent loss of material from the bed. It is concluded that saltating sand grains can rupture weak crusts under even moderate wind conditions, and that the rate of erosion will depend on the shape of the distribution

  • Due to particular soil and climate conditions and inappropriate agricultural practices, Central Aragón (NE Spain) is a semiarid region prone to land degradation by wind erosion. A field study was conducted during the summer 1995 to provide a first
  • quantification of wind erosion in agricultural soils of this region. This paper focuses on the mouldboard ploughing experiment, analysing in detail changes in vertical dust flux with time in response to changes in soil surface erodibility.

  • Soil erosion and desertification are severe problems in Iceland. One of the most distinctive erosion forms in Iceland is an erosion escarpment, termed robafard in Icelandic, where andosols are being truncated from the surface and barren desert
  • is left behind. They constitute a major erosion problem in the country. Other means of erosion are, however, equally as important in destroying vegetated andosol ecosystems, especially sand encroachment, but none is as distinctive on the landscape
