Abstract: An investigation of three‐dimensional (3‐D) turbulent structure, including turbulence‐driven secondary currents in compound open‐channel flows, is a very important topic in hydraulic and river engineering, as well as in ...

Abstract: Velocity measurements with a fiber‐optic laser‐Doppler anemometer were conducted in steep open‐channel flows over smooth and incompletely rough beds. The channel slopes were changed between 1/500 and 1/25 by steps, and as ...

Abstract: Basic knowledge of turbulent structures in open‐channel flows are now available from accurate experimental data that were obtained using a laser Doppler anemometer in laboratory flumes. Many of these experiments have, ...
