Downstream changes in riverbank sediment sources and the effect of catchment size
Study region: In this study, we compiled and analyzed the results of previous sediment fingerprinting research that examined the riverbank as one of the sediment sources, representing 118 catchments across the globe, most of which were located in the UK (

Fingerprinting sediment sources in a typical karst catchment of southwest China
Due to the complex hydrogeological conditions in karst regions, it is difficult to measure sediment source contributions at a catchment scale directly. The objective of this study was to quantify the relative contributions of sediment sources and their ...

Sediment Fingerprints: A forensic technique using quartz sand grains [PDF]
The analyses of 738 soil and sediment samples taken during the investigation of 20 forensic cases are combined in a database for retrospective comparisons. Quartz sand grain surface textures are combined into grain types which are analysed at one of five orders of classification.

Composite fingerprinting represents an effective method of reconstructing sediment-source changes in remote areas where long-term hydrological and sediment accretion records do not exist. A ca. 50-year record of sediment deposition was determined for a

Uncertainty Estimation in Stream Bed Sediment Fingerprinting Based on Mixing Model [PDF]
Uncertainty associated with mixing models is often substantial, but has not yet been fully incorporated in models. The objective of this study is to develop and apply a Bayesian-mixing model that estimates probability distributions of source ...

Evaluating tracer selection for catchment sediment fingerprinting [PDF]
Recent sediment fingerprinting research has shown the sensitivity of source apportionment results to data treatments, tracer number, and mixing model type. In light of these developments, there is a need to revisit procedures associated with tracer selection in sediment fingerprinting studies.

Excess diffuse fine sediment losses from agriculture are associated with a reduction in the ecological status of lakes and rivers. Agri-environment initiatives aim to help reduce these excessive losses through targeted on-farm advice and capital grants ...

Integrated approach to study river fluxes, water and sediment sources apportionment in sparsely monitored catchment [PDF]
The paper presents an integrated approach for the apportionment of water and sediment sources and pathways in ungauged territories. The approach comprises various elements such as a large-scale semi-distributed hydrological and erosion model (using ...
