Energetic tidal-stream environments are characterized by frequent, variable, yet broadly
predictable currents containing ephemeral flow structures that change across multiple spatio …

Research into fluvial dunes spans disciplines, studies at grain to reach scales, and
methodological approaches that include theoretical, experimental, numerical and field …

Numerical computation methods are used more and more as tools for solving hydraulic and
environmental engineering problems, and as turbulence mostly plays an important role in …

A model of sand transport in water is produced by combining a turbulence‐resolving large
eddy simulation (LES) with a discrete element model (DEM) prescribing the motion of …

This study employs the large-eddy simulation (LES) method to investigate the interaction of
submarine sediment flows with extensive shear behavior and ambient water. This method is …

A prominent control on the flow over subaqueous dunes is the slope of the downstream
leeside. While previous work has focused on steep (~ 30°), asymmetric dunes with …

A large-eddy simulation (LES) of a laboratory-scale horizontal axis tidal stream turbine
operating over an irregular bathymetry in the form of dunes is performed. The Reynolds …

The use of multiphysics computational fluid dynamics (CFD) approaches to simulate surface–
subsurface flow processes is evaluated by comparison with flume experiments on current …

Weirs or bed sills are low-head hydraulic structures used for bed stabilization, raising
upstream water level, and reducing flow velocity. During high-flow events, the weir is fully …

The method of large-eddy simulation (LES) is used increasingly to address research and
engineering problems of modern hydraulics. LES simulates directly the large-scale motion of …
