Downstream changes in riverbank sediment sources and the effect of catchment size

open access: yesJournal of Hydrology: Regional Studies, 2023
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

open access: yesInternational Soil and Water Conservation Research, 2020
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 ...

Using Source Fingerprinting Techniques to Investigate Sediment Sources during Snowmelt and Rainfall Erosion Events in a Small Catchment in the Black Soil Region of Northeast China

open access: yesLand, 2023
Concern for the offsite impact of eroded sediment and the need to develop effective catchment sediment management strategies has directed attention to the need for an improved understanding of the primary sediment sources within catchments and the ...

Sediment Fingerprints: A forensic technique using quartz sand grains [PDF]

open access: yesScience & Justice, 2006
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.

Sediment provenance in the Shudu Lake basin, northwest Yunnan Province, China, as revealed by composite fingerprinting

open access: yesDIE ERDE: Journal of the Geographical Society of Berlin, 2013
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]

open access: yesDesert, 2012
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 ...

Exploring Suspended Sediment Dynamics Using a Novel Indexing Framework Based on X‐Ray Diffraction Spectral Fingerprinting

open access: yesWater Resources Research, 2023
Understanding the origins and hotspots of suspended sediments is crucial for safeguarding the biotic communities and for management of water quality in river‐reservoir systems.

Evaluating tracer selection for catchment sediment fingerprinting [PDF]

open access: yesJournal of Soils and Sediments, 2018
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.

The potential for colour to provide a robust alternative to high-cost sediment source fingerprinting: Assessment using eight catchments in England

open access: yes, 2021
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]

open access: yesProceedings of the International Association of Hydrological Sciences, 2019
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 ...
