| 摘 要： | In this paper, two problems on dynamical sedimentology in the sea area near the Huanghe(Yellow) River Seaport are studied. Firstly, with synchronously observed data of bed-load trap and winds, starting and transporting dynamical mechanism of sediments on the intertidal shoal is analysed and studied. It is considered that starting and diffusing of sediments on the intertidal shoal near the Huanghe Seaport are controlled by waves and their surf currents. Secondly, with the help of data observed through observation concentration of suspended sediments, current velocity and wave height, starting and diffusing dynamical mechanism of sediments on the seabed near the Huanghe Seaport are analysed. It is considered that at a water depth of about 15 metres, starting and diffusing of the sediments are mainly controlled by tidal currents and at 5 metres or on the intertidal shoal by waves. At about 10 metres, their effects are rather similar.
