| description abstract | Unsteady flow properties are experimentally studied in an open channel with a rough bed. A recently developed acoustic Doppler velocity profiler (ADVP) is used to obtain instantaneously the flow profiles. From these measurements, using the Fourier components method, the mean velocities, the turbulence intensities and the Reynolds-stress profile, are obtained. Thirty-three different hydrographs are experimentally investigated. The experimental results show several things. First, unsteady flow can be characterized by the overall unsteadiness parameter, Γ | |
