Comparative study using spectroscopic and mineralogical fingerprinting for suspended sediment source apportionment in a river-reservoir system [PDF]

The need to control soil erosion has received increasing attention, but quantitative data on the sources of suspended sediment in many river–reservoir systems is still lacking.

Fingerprinting using compound-specific δ13C of n-alkanes reveals the temporary role of paddy fields as a secondary source for watershed sediment loss

International Soil and Water Conservation Research
Fingerprinting generates reliable sediment provenance information which supports devising policy or practical strategies for soil conservation and sediment management, but it remains challenging in areas with fragmented landscapes and diverse land use ...

Sediment fingerprint tracing: unravelling provenance of freshly deposited sediment in the Rhine River

Journal of Soils and Sediments
Abstract Purpose Quantifying and understanding fine sediment transfers from catchment sources to large river deltas is crucial for effective, integrated river basin management. This study aimed to identify the source areas of fine sediments contemporary deposited along the Rhine River.

Source fingerprinting sediment loss from sub-catchments and topographic zones using geochemical tracers and weathering indices

Application of sediment source fingerprinting techniques to generate reliable information on sediment sources is growing, because of the global environmental importance of elevated fine-grained sediment mobilisation and delivery to rivers.

Methodology for Integrating Isotopic and Nuclear Techniques to Assess Soil and Water Degradation in Terrestrial and Aquatic Ecosystems

Land
Isotopic and nuclear techniques, including fallout radionuclides (FRNs), fingerprinting (FP), and isotope hydrology (IH), are essential tools for assessing soil and water degradation. However, as in state-of-the-art reviews, isolated application of FRNs,

Fingerprinting sediment source: the example of a drainage basin in Devon, UK [PDF]

, 1986
In view of the many difficulties associated with the determination of the source of suspended sediment transported by a stream, the 'fingerprinting' technique which employs sediment properties to identify the source offers considerable potential. Several

Use of geochemical tracers to determine the sources for Riverine sediment with different sizes in a forest-agricultural watershed, northern Iran

Environmental and Sustainability Indicators
Because sediment sources, topography, and runoff vary, sediments generated in different parts of a watershed differ in size and properties, which affects the transport of various elements and contaminants.

Sediment fingerprinting for calibrating a soil erosion and sediment yield model in mixed land use watersheds

, 2015
This research estimates sediment yield contributed from surface mining soils, stream banks, and forest soils using sediment fingerprinting with isotope tracers coupled with soil erosion and sediment yield modeling in mixed land use watersheds. New tracer

Influence of Composite Sediment fingerprinting in identifying the sources of suspended sediments of a semiarid reservoir

Abstract Sediment source fingerprinting is intended to provide the source of the sediment carried in fluvial systems. The suspended sediment load carried by a river or stream will be a mixture of sediment from many sources and sites within the contributing catchment. This study uses sediment fingerprinting approach to investigate the sources of
