Abstract: N-S equations and TUMMAC method are used to simulate evolution of a wave train and to trace free-surface movement. With the model to described turbulence effect for wave propagating and sediment transporting. The turbulence intensity and sediment concentration have been resolved. Some results from these simulations for the time-averaged vertical suspended sediment concentration profiles are compared with that measured in a wave flame. This simulation makes it possible to examine in detail the mechanism of sediment entrainment, vortex formation and convection. This work contributes to knowledge about wave-sediment interactions and to understanding of sediment transport mechanics.
