We present results from Euler–Lagrange simulations of turbulent flow over an erodible
monodisperse bed of particles at a shear Reynolds number of R e τ= 180. The Galileo …

This research focuses upon size segregation mechanisms in bedload sediment transport.
Simplified experiments with fine grain inputs to a mobile coarse bed in equilibrium were …

Steep-creek beds are macroscopically rough. This roughness causes channelized flow
material to decelerate and dissipate energy, which are accounted for by depth-averaged …

In this numerical study, we are interested in the prediction of a mono-disperse dilute
suspension particle-laden flow in the typical lock-exchange configuration. The main …

The flow of segregated bidisperse assemblies of particles is of major importance for
geophysical flows and bedload transport in particular. In the present paper, the mobility of …

Gravity-driven turbulent bedload transport has been extensively studied over the past
century in regard to its importance for Earth surface processes such as natural riverbed …

Morphodynamic processes on Earth are a result of sediment displacements by the flow of
water or the action of wind. An essential part of sediment transport takes place with …

Empirical sediment transport models have common characteristics suggestive of the
underlying physics, but mechanistic explanations for these characteristics are lacking due to …

Turbulent bedload transport represents the main contribution to the riverbed morphological
evolution, and associates the non-trivial collective granular behavior with a turbulent fluid …

Previous modeling studies of hyporheic exchange induced by moving bedforms have used
a moving reference frame, typically corresponding to an individual moving bedform …
