Exploring fine sediment dynamics and the uncertainties associated with sediment fingerprinting in the Nene river basin, UK
… and ecological status of freshwater bodies. Fine sediment has been shown to be a major cause of the degradation of lakes and rivers, and as a result research in geomorphology has been directed towards the understanding of fine sediment dynamics. It was identified by a review of published …

ADVANCING METHODS FOR APPORTIONING THE SOURCES OF SEDIMENT IN RIVERS: COMBINING SPECTROSCOPY AND STABLE ISOTOPES WITH BAYESIAN MIXING MODELS
Sediment fingerprinting is a commonly employed technique for estimating sediment contributions from various eroding terrestrial sources to fluvial sediment load via a mixing model approach. However, there remain significant shortcomings in sediment fingerprinting practice, specifically relating to …

Spectral fingerprinting
… the need for an improved understanding of sediment dynamics. This involves the accurate assessment of erosion rates and sediment transfer, yield and origin. A variety of methods exist to capture these processes at the catchment scale. Among these, sediment fingerprinting, a technique to …

Andean sediment response to natural and anthropogenic changes at the catchment scale
… erosion is contributing to increased levels of sediment in river systems threatening crucial river functions, including crop irrigation, drinking water, and hydroelectricity. Past studies in the Andes regarding soil erosion have indicated that human activities have accelerated soil erosion and …

Analysis of sediment dynamics in intensively managed landscapes
The flux of fine sediment within agricultural watersheds is an important factor determining the environmental quality of streams and rivers. Human activity has significantly altered the hydrological and biogeochemical cycles within terrestrial and aquatic environments through agricultural …

Soil erosion and suspended sediment dynamics in intensive agricultural catchments
Excessive delivery of fine sediment from agricultural river catchments to aquatic ecosystems can degrade chemical water quality and ecological habitats. Management of accelerated soil losses and the transmission of sediment-associated agricultural pollutants, such as phosphorus, is required to …

Sustainable Land-Use Management for the Conservation of the Freshwater Pearl Mussel: Sediment Flux and Provenance
… (FPM) populations are believed to be diffuse sediment losses associated with agriculture and forestry. The contribution of anthropogenic activity to river sediment load is of increasing global concern (Duerdoth et al. (2015). Excessive sedimentation of watercourses can reduce habitat quality, …
