Abstract

A sediment transport model based on the two-phase mass and momentum equations is introduced with appropriate closures on the near bed boundary conditions and fluid turbulence. The pick-up function proposed by van Rijn is implemented as the boundary condition for the vertical sediment mass flux. The performance of the proposed model is tested against seven laboratory U-tube measurements. It is found that the two-phase model has an adequate ability to predict the time-averaged concentration under various combinations of maximum free-stream velocity and oscillatory period. However, some discrepancies are observed in the comparison of the time history of the concentration profiles. We anticipate that this is due to the approximations in the near bed boundary conditions in the sediment-phase. Some future work towards a better understanding of the near bed boundary conditions is suggested.
