Grid‐based sediment tracing approach to determine sediment sources
Land Degradation & Development, 2019 AbstractThe diffusive and nonspecific nature of nonpoint source contaminants such as sediment makes their management and mitigation challenging. Conventional source‐based tracing techniques for sediment simply apportion downstream sediment load to diffuse upstream sources classified by a limited number of source types including underlying rock type ...

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

Holocene sediment dynamics in an upland temperate lake catchment : climatic and land-use impacts. [PDF]
, 2009 Accelerated erosion and transport of fine sediment from upland temperate catchments can reflect increased erosivity and/or erodibility, due in turn to climatic and/or human forcing.

Unmix Optimum analysis of PAH sediment sources. [PDF]
Sci Total Environ, 2019 Unmix Optimum (UnmixO) was developed to analyze data, such as sediment PAH data, that were resistant to existing methods of multivariate analysis. Using a geometrical approach, UnmixO uses multiple advanced nonlinear optimization algorithms to find potential sources that obey non-negativity constraints while optimally fitting the data.

Sediment fate and transport: Influence of sediment source and rainfall [PDF]
Journal of Hydrology, 2021 Abstract The capability of hydrologic models to spatially simulate the changes in hydrologic processes, like precipitation, is an important consideration in capturing the impacts of these processes on sediment prediction across the domain. Radar-derived precipitation (RDP) provides an enhanced detail of rainfall characteristics in time and space ...

Fingerprinting sediment sources in a typical karst catchment of southwest China
International 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 ...
