Long duration PIV measurements in rough-bed (glass beads) open-channel flow (OCF)
reveal that the pre-multiplied spectra of the streamwise velocity has a bimodal distribution …

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 …

Large-scale coherent structures (LSCSs) in rough-bed open-channel flow (OCF) are
significant in turbulence research. A recent breakthrough is the bimodal feature of LSCSs on …

Rough-bed open-channel flows (OCFs) are ubiquitous in rivers and canals. However, the
scaling and energy contents of very-large-scale motions (VLSMs) in such flows remain …

This study examines shallow uniform flow and spanwise-sheared flow behind a vertical
splitter plate over a uniformly rough bed. The primary objective is to assess the presence of …

This paper investigates the existence and scaling of the so-called large-scale and very-large-
scale motions (LSMs and VLSMs) in non-uniform turbulent open-channel flows developing …

Acoustic Doppler velocity profiler (ADVP) measurements of instantaneous three-
dimensional velocity profiles over the entire turbulent boundary layer height, δ, of rough-bed …

In this thesis, detailed experiments are performed to study the effect of the flow depth on
turbulent structures in smooth and rough bed open channel flow. When the rough bed is …

It is widely acknowledged that streamwise ridges on the bed of open-channel flows generate
secondary currents (SCs). A recent discovery of meandering long streamwise counter …

The dynamics of large-scale coherent structures (LSCS) are investigated in a rough-bed
flow over the whole water column and longitudinal and transverse turbulent fluxes of …
