Suspended Sediment Transport in Lianyungang Nearshore Area

Article Preview

Abstract:

Hydrological observations at 13-19 stations were conducted synchronically in Lianyungang nearshore area during the spring and half tide in winter and summer respectively. Data of suspended sediment concentrations (SSC), currents and water levels at observation stations were used to study the suspended sediment transport by the method of mechanism decomposition. The advection transport plays an important role during the whole observations, with the direction generally same to the flood current. The tidal pumping transport plays a significant role in the nearshore area, which is the main factor for the periodical variation of SSC. The direction of the tidal pumping transport is mainly toward the land, which indicates that the periodic component of SSC is transport to the land with the form of peaks in the bottom layer. The results may help to improve understanding of the coastal engineering and environmental applications related to sediment transport.
