3Upscaling the use of fallout radionuclides in soil erosion and sediment budget investigations:Addressing the challenge显示文摘The application of fallout radionuclides in soil erosion investigations and related sediment budget studies has provided a widely used tool for improving understanding of soil erosion and sediment transfer processes.However,most studies using fallout radionuclides undertaken to date have focussed on small areas.This focus on small areas reflects both the issues addressed and practical constraints associated with sample collection and analysis.Increasing acceptance of the important role of fine sediment in degrading aquatic habitats and in the transfer and fate of nutrients and contaminants within terrestrial and fluvial systems has emphasised the need to consider larger areas and the catchment or regional scale.The need to upscale existing approaches to the use of fallout radionuclides to larger areas represents an important challenge.This contribution provides a brief review of existing and potential approaches to upscaling the use of fallout radionuclides and presents two examples where such approaches have been successfully applied.These involve a national scale assessment of soil erosion rates in England and Wales based on 137Cs measurements and an investigation of the sediment budgets of three small/intermediate-size catchments in southern Italy.D.E.Walling P.Porto Y.Zhang P.Du 2014International Soil and Water Conservation Research2014,2,3:0
