Sediment fingerprinting in fluvial systems: review of tracers, sediment sources and mixing models [PDF]

open access: yesInternational Journal of Sediment Research, 2013
Suspended sediments in fluvial systems originate from a myriad of diffuse and point sources, with the relative contribution from each source varying over time and space. The process of sediment fingerprinting focuses on developing methods that enable discrete sediment sources to be identified from a composite sample of suspended material.

An exploratory study on the use of different composite magnetic and colour fingerprints in aeolian sediment provenance fingerprinting

open access: yesCATENA, 2021
Abstract There is an urgent need for reliable and cost-effective sediment source tracing techniques for apportioning aeolian sediment (sand dune) sources for guiding the selection of best management practices for wind erosion control. Accordingly, the main aim of this study was to quantify the contributions of aeolian sources to sand dune target ...

Fingerprinting Suspended Sediment Sources in an Urbanized Watershed [PDF]

open access: yesWater, 2018
The elevated supply of fine-grained sediment to a river system negatively impacts the water quality and ecosystem health. Therefore, quantification of the relative contribution from different sources to in-stream sediment is of major interest to target sediment mitigation best management practices (BMPs).

Estimating typical sediment concentration probability density functions for European rivers [PDF]

open access: yes, 2005
Sediment in rivers is linked with qualitative and quantitative water problems throughout Europe. Sediment supply and transfer are part of a natural process of minimising gradients in the landscape.

The efficiency of elemental geochemistry and weathering indices as tracers in aeolian sediment provenance fingerprinting [PDF]

open access: yes, 2022
Confirmation of cost-effective and reliable tracers for aeolian sediment (sand dune) source fingerprinting warrants further research. Accordingly, the main objective of the work reported in this paper was to investigate the efficiency of weathering ...

The Role of Paddy Fields in the Sediment of a Small Agricultural Catchment in the Three Gorges Reservoir Region by the Sediment Fingerprinting Method

open access: yesLand, 2023
Identifying sediment sources is a prerequisite for developing sediment management strategies. Erosion sediment derived from a small agriculture catchment is an important component of sediment inflow in the Three Gorges Reservoir Area.

Sediment Fingerprinting in the Gheshlagh Dam Watershed, Sanandaj, Using the Geochemical Method based on the Two-Stage Statistical Analyses [PDF]

open access: yesپژوهش‌های آبخیزداری, 2021
Determination of the role of each lithological unit in sediment production is an important priority of watershed management. The geochemical method provides the means to determine the origin of sediments in the Gheshlagh Dam, Sanandaj.

Sediment Source Fingerprinting of the Lake Urmia Sand Dunes [PDF]

open access: yesScientific Reports, 2018
AbstractAeolian sand dunes are continuously being discovered in inner dry lands and coastal areas, most of which have been formed over the Last Glacial Maximum. Presently, due to some natural and anthropogenic implications on earth, newly-born sand dunes are quickly emerging.

Assessment of the Applicability of the Mixing ModelsUsed in the Sediment Fingerprinting of Different SourcesDeposited in the Lavar Fin Reservoir, the Province of Hormozgan [PDF]

open access: yesپژوهش‌های آبخیزداری, 2019
Identification of the erosion-pron parts of a watershed is of at most importance if the soil conservation activities are to be implemented on it to mitigate sedimentation into the flood-receiving reservoir.

Separation of the Relative Contribution of Different Land Covers in Bed Sediment Yield in Vaz River Using Geochemical Characteristics [PDF]

open access: yesپژوهش‌های آبخیزداری, 2022
Identification of sediment resources and their associated pollutants and contribution separation of land uses / land cover in sediment production is a valuable tool in spatial prioritization of soil conservation practices at watersheds. The present study
