Flow-sediment turbulent ejections: interaction between surface and subsurface flow in gravel-bed contaminated by fine sediment
(MDPI, 2020)
Several researchers have studied turbulent structures, such as ejections, sweeps, and outwards and inwards interactions in flumes, where the streamwise velocity dominates over vertical and transversal velocities. However, ...
The Effects of Sediment Classification Pattern on a Water Column Organism, Ceriodaphnia dubia
(2018-06-01)
The sediment compartment stands out because it functions as both a temporary sink of pollutants and a potential source of these elements that may become available to the water column.This study aimed to correlate the ...

(2018)
The sediment transport driven by a river or a channel flow is a phenomenon that operates at different scales. At the smallest scales, the coherent structures of the turbulent boundary layer are the mechanisms that govern ...
Reservoir and contaminated sediments impacts in high-Andean environments: Morphodynamic interactions with biogeochemical processes
(2014)
Rapid changes due to anthropic interventions in high-altitude environments, such as the Altiplano
region in South America, require new approaches to understand the connections between
physical and biogeochemical processes. ...
Predicting bioaccessibility of contaminants of emerging concern in marine sediments using chemical methods
(2018-04-01)
Purpose: A comparison was made between three chemical methods to predict bioaccessibility of triclosan (TCS), bisphenol A (BPA), and 17α-ethynylestradiol (EE2) in marine sediments, involving an exchangeable (E) value, ...
Kinetics and Adsorption Isotherms of Bisphenol A, Estrone, 17 beta-Estradiol, and 17 alpha-Ethinylestradiol in Tropical Sediment Samples
(Springer, 2012-01-01)
The sorption of four endocrine disruptors, bisphenol A (BPA), estrone (E1), 17 beta-estradiol (E2), and 17 alpha-ethinylestradiol (EE2) in tropical sediment samples was studied in batch mode under different conditions of ...

Fine Sediment Input and Benthic Fauna Interactions at the Confluence of Two Large Rivers
(University of Tehran, 2016-01)
Several studies suggest that invertebrate abundance and richness are disrupted and reset at confluences. Thus, junctions contribute disproportionately to the overall aquatic biodiversity of the river. In general terms, ...
Sediment dynamics modulated by burrowing crab activities in contrasting SW Atlantic intertidal habitats
(Academic Press Ltd-elsevier Science Ltd, 2008-11)
Biogenic bottom features, animal burrows and biological activities interact with the hydrodynamics of the sediment–water interface to produce altered patterns of sediment erosion, transport and deposition which have ...
