Heavy metal concentrations in water and sediments from affluents and effluents of mediterranean chilean reservoirs
(Sociedad Chilena Química, 2016)
RIVER flows have constant interaction between water and bed sediments; for this reason knowledge of the characteristics of the sediments is fundamental to understand water chemistry. This study determined the concentrations ...
Sediment grain size distribution and heavy metals determination in a dam on the Parana River at Ilha Solteira, Brazil
(Taylor & Francis Inc, 2009-07-15)
This paper reports on a preliminary evaluation of the grain size distribution of cadmium, lead and copper in sediment from Catarina Beach, Ilha Solteira, in the state of São Paulo, Brazil. Surface sediments were fractionated ...

Assessing sediment yield and streamflow with SWAT model in a small sub-basin of the Cantareira System
(Sociedade Brasileira de Ciência do Solo, 2022)
Morphology, flow structure, and suspended bed sediment transport at two large braid-bar confluences
(American Geophysical Union, 2009-05)
Mid-channel bars and their associated confluences are key morphodynamic nodes within braided rivers, with past studies having investigated the morphodynamics of small natural channels or laboratory models with relatively ...
Characterization of bedload intermittency near the threshold of motion using a Lagrangian sediment transport model
(2017)
At the smallest scales of sediment transport in rivers, the coherent structures of the turbulent boundary layer constitute the fundamental mechanisms of bedload transport, locally increasing the instantaneous hydrodynamic ...
