Abstract: An investigation of cellular secondary currents, i.e., three‐dimensional flow patterns, is very important in hydraulic engineering because these currents might cause three‐dimensional sediment distributions and bed ...

Abstract: A powerful two‐color Laser Doppler Anemometer (LDA) system, with direct digital signal processing has been used to measure accurately the longitudinal and vertical velocity components in two‐dimensional, fully‐developed ...

Abstract: Mechanism of sediment transport is composed of complicated interactions between turbulent flow, particle motion, and bed configurations. Of particular significance is the interaction between turbulence and particle motion, ...

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: Unsteady depth-varying open-channel flows are really observed in flood rivers. Owing to highly accurate laser Doppler anemometers (LDA), some valuable experimental databases of depth-varying unsteady open-channel flows are ...

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, ...

Abstract: Steps leading to the numerical study of the hydrodynamic behavior of a compound open channel are described. The method uses an algebraic stress model imbedded, together with an energy‐dissipation model, in a parabolic ...

Abstract: The hydrodynamic response of the turbulent flow in a compound rectangular open channel to the flood‐plain depth, roughness, and symmetry, and to the channel Reynolds number is demonstrated. The flow in the four basic ...
