Deicing road salts have been increasingly used in the United States over past 80 years. Previous studies shown that these can deteriorating effects on freshwater organisms. Here, we hypothesize introduction of to streamwater also boost aggregation mud particles suspended water column. Such aggregation, known as flocculation, enhances deposition rates and may lead increased accumulation fine sed...

We demonstrate that DNA sediments in the presence of millimolar concentrations of zinc or related metal cations and that EDTA entirely dissolves the sediment. The sedimentation is promoted by alkaline pH but the pH dependence is abolished by submillimolar concentrations of phosphate anions. We suspect that the metal cations generate sedimenting particles of insoluble hydroxides or phosphates fo...

Environmental 137Cs adsorbed on fine sediments has many uses as a tracer in erosion and sedimentation studies. The determination of sedimentation rates in lakes and reservoirs using 137Cs as a geochronological marker is described in detail. From a survey of literature sources it is shown that 137Cs levels in soils and sediments can be a powerful tool for the identification and quantification of...

An interdisciplinary research in the Late Quaternary loess-like cover deposits valley of Kuytunka River (Western Transbaikalia) was aimed at reconstructing conditions and dynamics regional sedimentation. Particular attention is paid to assessing information capacity methods involved therein: lithofacies analysis, grain-size petromagnetic lithochemical analyses. It shown that results each method...

This study examines the connections between recent terrestrial sedimentation and carbon burial and discusses the implications for the global carbon cycle. Land-use change has mobilized large quantities of sediment, causing sediment to accumulate on valley floors, altering the terrestrial sediment cycle. This accumulated sediment may be sequestering much of the “missing carbon.” Using a combinat...

Current soil erosion and reservoir sedimentation modelling at the meso-scale is still faced with intrinsic problems with regard to open scaling questions, data demand, computational efficiency and deficient implementations of retention and re-mobilisation processes for the river and reservoir networks. To overcome some limitations of current modelling approaches, the semi-process-based, spatial...
