Abstract: Hydrological observation was carried out in the Yellow River Estuary in September, 2003, in order to study the temporal and spatial distribution of suspended sediments in the tidal bank of the Yellow River Estuary. The result shows that current makes more contribution to the sediment resuspension when ripples dominate; while wave renders more effect on sediment resuspension under smooth-wave. There are not only sediment concentration peaks caused by sediment resuspension by current or wave, but also the peaks of sediments by wave-induced resuspension and transported suspension by current.
