Reliable full-scale prediction of drag due to rough wall-bounded turbulent fluid flow remains
a challenge. Currently, the uncertainty is at least 10%, with consequences, for example, on …

This paper reviews recent work on flow and transport in channels with submerged
vegetation, including discussions of turbulence structure, mean velocity profiles, and …

In order to understand the effects of the wall permeability on turbulence near a porous wall,
flow field measurements are carried out for turbulent flows in a channel with a porous bottom …

Several models for the vertical distribution of the double-averaged (in time and in the plane
parallel to the mean bed) longitudinal velocity in the flow region between roughness troughs …

Long-duration particle image velocimetry measurements in rough-bed open-channel flows
(OCFs) reveal that the pre-multiplied spectra of the streamwise velocity have a bimodal …

This study focuses on the double-averaged (DA) turbulence characteristics and the local
flow characterization in the flow zones over and within the flow-gravel-bed interface. The …

In the fully rough regime, proposed models predict a scaling for a roughness heat-transfer
coefficient, eg the roughness Stanton number can remain an apt description of the flow …

We investigate the turbulent structure of shallow open channel flows where the flow depth is
too small (compared with the roughness height) to form a logarithmic layer but large enough …

Streamwise–wall-normal (plane data, although low-and high-speed streaks are also
observed near the anisotropic porous walls, large-scale spanwise patterns appear at a …

In this paper, the macroscopic equations of mass and momentum are developed and
discretized based on the smoothed particle hydrodynamics (SPH) formulation for the …
