This paper describes a two stage sediment budgeting technique to estimate the total volume of metal contaminated sediment stored within the River Swale, UK. This operates by dividing the catchment, and likely sediment stores, into two physically and geomorphologically distinct areas (tributaries and the trunk channel). The AA. use a combination of techniques to establish the volumes of metal contaminated sediment remaining within the River Swale. Firstly, using detailed field sampling and a geographical information system (GIS), they estimate the volumes of sediment remaining within one formerly mined tributary (Gunnerside Beck) which is then extrapolated to represent the contaminant volumes on other tributaries of the River Swale. Secondly, combining fresh field data with a range of existing data, volumes of contaminated sediment on the main stream of the River Swale are established. This two tier approach shows that significant volumes of contaminated sediment remain within the River Swale and it may take over 5000 years for all of the metal rich sediment to be removed from the catchment
