The water surface response to subcritical turbulent flow over a backward-facing step (BFS) is
studied via high-resolution large-eddy simulation (LES). The LES method is validated first …

Estimating river discharge requires simultaneous measurement of velocity and flow depth.
While surface velocities are relatively easy to measure using noncontact techniques, depth …

Over the last two decades, interest in the free-surface behaviour of gravity-driven shallow
turbulent flows has increased considerably. It is believed that observation of free-surface …

Large eddy simulations (LESs) of turbulent flow in partially filled pipes at various filling
degrees are conducted to investigate the response of the water surface to the turbulence …

In turbulence near a free surface, strong vortices attach to the surface, creating surface
imprints visible as nearly circular 'dimples'. By studying these imprints in direct numerical …

The free surface at an air–water interface can provide information regarding bathymetric
complexities, as well as the subsurface flow. We present a comparison of the performance of …

This work presents a novel method to reconstruct the frequency-wavenumber spectrum of
water waves based on the complex acoustic Doppler spectra of scattered sound measured …

Optical methods are increasingly used as a means to determine the flow vel ocity at the
surface of rivers. If applied in the absence of visible physical tracers (eg, floating debris) …

This research presents an application of the sampling moiré method, a novel technique
originally developed for measuring slight deformation of a static object such as a plate, to …
