The silting process of urban reservoirs has been occurring in many regions across the world. However, identifying main sources sediment and controlling are still unsolved problems regions, mainly developing countries such as Brazil. In this study, we identify which land use most influences siltation reservoirs, how different tributary streams contribute to two located Campo Grande, Midwestern T...
Sediment fingerprinting experiments have been used to demonstrate the sensitivity of numerical mixing model outputs different particle size distributions in source materials and experimental sediment mixtures. The study aims examine further grain effects distribution geochemical elements by soils through a laboratory experiment simulating sorting processes, investigate if fractions are influenc...
Here, we use DGGE fingerprinting and barcoded pyrosequencing data, at six cut-off levels (85-100%), of all bacteria, Alphaproteobacteria and Betaproteobacteria to assess composition in the rhizosphere of nursery plants and nursery-raised transplants, native plants and bulk sediment in a mangrove habitat. When comparing compositional data based on DGGE fingerprinting and barcoded pyrosequencing ...
A sediment fingerprinting approach was applied to identify dominant sources in an area where soil conservation measures (i.e. terracing) had been carried out on steep, intensively cultivated lands but the outcome unknown. The wider purpose provide scientific evidence inform decisions erosion control and mitigation strategies could be further targeted. Geochemical fingerprints were used quantify...

Abstract Purpose Lake Victoria has been increasingly silting over the past decades, impacting water quality and loss of biodiversity. Sediment control strategies require information on relative absolute contributions sediment from different sources. However, to date, there is no continuous monitoring flux or in any tributaries, prohibiting an assessment scale problem. The aim this study was tra...
