FingerPro and D-MixSIAR: New fingerprinting development approaches for tracking sediment provenance

Abstract

Fingerprinting techniques provide a means of assembling valuable information on the principal fine-grain sediment provenance at catchment scale. However, the outcome of these studies often depends on the type of model and the selection of the tracers used to determine the relative contribution from different sources. Despite the rapidly increasing number of studies reporting the use of fingerprinting as a tool to detect the sediment provenance, there is a need to refine or clarify existing approaches and the key components of the current methodological procedures.
