| Abstract: | Based on the observation data of suspended sediment concentration (SSC) and ocean current, we applied the tidal current quasi-harmonic method for short-term data to analyze the tidal current characteristics, and to discuss the dynamics relation between SSC and the tidal current. The research results show that the tidal current in the studied area can be classified as regular semidiurnal tidal current. The north component of semidiurnal current is generally stronger than the east one. The tidal current is mainly the rectilinear. As the distance is farther away from the shore, the rotation is stronger. At flood tide, the tidal current is in the direction of SSE, and at ebb tide, the current is in the direction of NNW. The SSC gradually reduces from the nearshore to offshore, and it increases from surface to bottom. The SSC vertical gradient in nearshore is larger than in offshore. The SSC shows obvious cyclical changes, in response to regular semidiurnal tidal currents. The maximum SSC appears after the maximum velocity. The suspended sediment mainly is transported in direction of south by tidal current, and the sediment discharge of the flood tide is larger than the ebb tide. |
