Characterization of bedload sediment transport in high slope rivers using hydraulic geometry theory
(Asce library, 2019)
In Ecuador, steep rough-bedded channels constitute the main component of mountainous drainage system. They provide sediment to milder-slope downstream channels. Thus, sediment transport represents a driving process in ...
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 ...
Initial Instabilities of a Granular Bed Sheared by a Turbulent Liquid Flow: Length-Scale Determination
(Abcm Brazilian Soc Mechanical Sciences & EngineeringRio De Janeiro RjBrasil, 2010)
Three-dimensional sand ripples as the product of vortex instability
(Elsevier Science IncNew YorkEUA, 2013)
Statistical Characterization of the Intermittency of Bedload Transport in Conditions Near the Threshold of Motion
(2015)
The dynamics of sediment particles in a flat bed channel is mainly determined by near bed coherent
structures of the turbulent boundary layer. These vortices are characterized by intense velocity
fluctuations, which ...
Sediment transport in steep Andean rivers with coarse bed material
(Universidad de Cuenca, 2022-05-05)
To improve the understanding of bedload sediment transport with the aim of proposing
estimations of its transport rates with greater accuracy, a comprehensive analysis was
developed. To investigate the former process, ...
