  • This paper demonstrates the potential for using a composite fingerprinting technique, incorporating both statistically verified composite signatures and a multivariate mixing model, to provide a preliminary integration of spatial provenance
  • and source type information for contemporary suspended sediment fluxes from the upper and middle reaches of the River Exe and River Severn, UK. A nested approach is adopted, whereby sediment origin is initially addressed in terms of the distinct spatial zones
  • constituting each study area, and then in terms of the precise source types within each of these spatial zones.

  • Sediment fingerprinting appears to offer a valuable alternative to direct monitoring for elucidating the provenance of suspended sediment and the relative importance of spatial zones or subcatchments comprising larger drainage basins. Against
  • this background, a quantitative composite fingerprinting technique, incorporating both statistically verified multicomponent signatures and a multivariate sediment-mixing model, has been employed to determine the spatial origin of contemporary suspended sediment

  • During a palaeoflood study of the Llobregat River in Catalonia, analysis of Cs 137 was carried out on slackwater flood deposits to obtain an improved flood chronology for the most recent flood sediments. The onset of measured caesium activity
  • estimates associated with the flood deposits, Cs 137 analysis and the instrumental peak discharge series, it was possible to identify the particular flood events responsible for the majority of the slackwater flood units.
