Description :
This paper describes the rates of soil loss and remobilisation in 2 sub-catchments within the Sydney Basin region, namely Kembla and Kentish Creeks, which drain to the Cordeaux reservoir. The total inventories of 137Cs in catchment soils were determined, a 137Cs-regression equation and a theoretical diffusion and migration model were used to established relationships between 137Cs inventories and the rates of soil loss. The findings suggest that sediment mobilised in the study sub-catchments are not likely to impact significantly on the water quality in the Cordeaux reservoir.
