Experimental Study on Suspended Sediment Transport in Unsteady Open-Channel Flow

Abstract

Recent studies of the turbulent structure of unsteady open-channel flow enable us to investigate the suspended sediment transport at unsteady flow. This study shows the temporal changes of the turbulent structure and the concentration distribution of the sediment-laden unsteady flow by flume experiments. Furthermore, the effect of theb ase flow, the unsteadiness and sand diameter on the phase lag between the peak of the flow depth and that of the suspension is studied by solving the linealized depth-averaged diffusion equation.
