Keywords:

  • scaling soil erosion models - in space and time;
  • characterization and prediction of erosion - integrating individual movements, producing fluxes of sediment movement;
  • direct measurement of erosion rates - using two broad techniques;
  • use of SDRs, demonstrating a fundamental point - data are not independent of the (conceptual) models used in research designs;
  • downscaling, interpolation of larger to smaller data extents - spacings or supports in terms of measurement scale;
  • statistical scaling in simple conditions;
  • sampling strategies, and erosion variability - scaling rates, accounting for characteristics of all these elements;
  • use of a digital elevation model (DEM) - in soil erosion model applications;
  • travel-distance approach - to scaling erosion predictions;
  • research frontier in scaling erosion models
