Abstract

The geochemical record preserved in overbank floodplain deposits is used in combination with a composite fingerprinting technique and the chronology provided by Cs 137 dateable horizons, to reconstruct recent changes in sediment sources in the Exe and Severn basins, UK. Composite fingerprints for discriminating potential source materials are identified from a suite of properties including heavy metals, trace metals and cation bases. These fingerprints are then compared with those of historical floodplain deposits using a numerical sediment mixing model
