| Abstract: | Marine dynamic process plays a decisive role in deposition and dispersion of sediment discharged from the Yellow River. In this paper, a 3 D dynamic and sediment model is used to analyse the relationship between the tidal current variations in the Yellow River mouth area and the sediment deposition discharged from the Yellow River. The mechanisms for the fluid mud formation and variation in the Yellow River mouth area and the seaward dispersion of sediment discharged from the Yellow river are well explained by the seasonal circulation and the tidal current distribution and variation. It is shown from the analysis results that there are different transport characteristics for the discharged sediments in flood and dry seasons and surface and bottom layers. |
