Title: A Study on Suspended Sediment Carrying Capacity in Combined Actions of Waves and Tidal Current
Abstract: The turbulent bursting theory is applied to study sediment carrying capacity in the combined actions of waves and tidal current in this paper. Based on space-time scales of turbulent bursting,the lifting flux of bed sediment is developed. Then,a theoretical equation for the equilibrium of near- bed-concentration of suspended sediment is established from the balance between the lifting and effective sedimentation fluxes. Hereon,according to the modes of sediment lifting by waves and sediment transporting by tidal current,a formula of sediment carrying capacity is established with the clear physical concepts and the consideration of the mechanism of sediment particles exchanging near bed. By verification,the calculated results are in good agreement with the measured data of the Yellow River delta.
