Abstract
N-S equations and TUMMAC method are used to simulate evolution of a wave train and to trace free-surface movement. With the k - w 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.
