Transport of size-graded and uniform sediment under oscillatory sheet-flow conditions

摘要

The present study concentrates mainly on the influence of sediment gradation on the wave-induced sediment transport and can be considered as a logical next step in an ongoing line of cross-shore sand transport research. The study focuses at improving our basic understanding of size-graded and uniform sand transport mechanisms inudcross-shore direction under oscillatory sheet-flow conditions. Sheet-flow is the dominant transport mode during storm conditions, when coastal and seabed erosion and deposition processes are generally very strong.
