Composite Fingerprint

Information on the source of the suspended sediment transported by a river is becoming an increasingly important requirement in sediment investigations. Such information is difficult to assemble by means of traditional monitoring strategies, but the 'fingerprinting' technique offers considerable potential. The use of composite 'fingerprints' in combination with a multivariate mixing model can provide a basis for determining the relative importance of both individual areas of a catchment and specific source types. The results of applying this approach to the 276-km² basin of the River Culm in Devon, UK are presented. A suite of nine fingerprint properties was employed as a composite fingerprint, and this permitted the relative contributions of seven source types to be established. These source types represented material derived from the surface af cultivated and pasture areas on each of the three main rock types and material eroded from channel banks. By collecting samples of suspended sediment at different times during individual floods, it was possible to document changes in the relative contributions of the various sources during each flood in response to runoff source and travel times. Although the multivariate fingerprint approach has a number of limitations, it also has considerable potential as a means of tracing sources of suspended sediment within a large drainage basin.

Early Pottery

A case study of the Neolithic comb ceramic site Pezmog 4 of the Kama culture presents a situation when results of radiocarbon dating change long-existing concepts concerning the development of archaeological events. Until the early 2000s, the chronology of the Kama culture, distributed mainly in the Kama and Vychegda River basins, has been based on comparative-typological analysis. Estimates of the age of this culture changed from the 3rd millennium BC in the 1950s to the 1st half of the 4th millennium BC by the 1990s. Research concerning the Pezmog 4 site in the central Vychegda River basin in 1999–2002 has abruptly changed this chronological understanding. The data obtained put the age of the early stage of Kama culture within the time range 5750–5620 cal BC and allowed us to propose the existence of another way of early pottery distribution in the forest zone of eastern Europe at the beginning of the 6th millennium BC. This innovation probably penetrated from the trans-Ural region.
