Abstract
Wave phenomenon in ocean often has the shape in the horizontal and vertical asymmetric waves when propagating in the near-zone with high non-linearity. The orbital velocity due to the wave asymmetriesand nonlinearities could generate the flow patterns that drives cross-shore sediment transport in the near-shore zone. A new calculation method for bottom shear stresses and bed-load sediment transport rate for the horizontal and vertical asymmetries waves proposed by1,2was implemented to model the concentration sediment and suspended sediment transport. The characteristics of the concentration sediment and suspended load induced by the horizontal and vertical asymmetries waves have been examined. The modeling results showed that the smaller α and the higher Ni indicate more wave skew-ness and more non-linearity of waves causing a higher the bottom shear stress and the net bed load transport while the net suspended load transport decrease with the decreasing of the wave skew-ness. The higher skewed waves indicated the higher acceleration causing increase the value of the net onshore transport rate for bed load sediment transport and decrease the value of the net offshore transport rate for suspended sediment transport.
