Abstract
It is quite necessary to reveal hydrodynamic characteristics in time-dependent compound open-channel flows, when rivers in flood are considered. In particular, there is almost no numerical analysis on unsteady compound open-channel flows. Therefore, in this study, 3-D time-dependent numerical turbulence model involved with a VOF method has been developed. Furthermore, unsteadiness properties, turbulence structures and their influences upon suspended sediment transport are examined numerically.
