Description :
The work reported in this contribution used a novel modelling framework to assess the impact of projected change in farming by 2015 on the relative input of the agricultural sector to the total suspended sediment load delivered to all rivers across England and Wales. It required national scale sediment source apportionment to assess the current contributions of diffuse agricultural and urban sector losses, channel bank erosion and point source discharges to the total suspended sediment loads delivered to all rivers. Results suggested that the agricultural sector dominates present day (year 2000) sediment inputs to rivers. Key limitations of the integrated modelling approach are discussed.
