Abstract

Sediment parameters of inter tidal flat are related to the depositional hydrodynamic conditions associated with the local sedimentary environment. During July August, 2000, 154 surface sediment samples were collected on the intertidal flat of Wanggang. The sediment samples are then analyzed using Mastersize2000. Further, the regression analysis shows that the significant relationships are present between the sediment parameters, and as well with ( M z Φ M d Φ). In addition, the grain size diameters decrease landward with the decreasing of the hydrodynamics. Five types of sediments have been identified for the Wanggang intertidal flat:fine sand, silty sand, sandy silt, silt and clayey silt. In brief, there are two main sediment types, i.e. silt and sand with the percentages of 57.8% and 42.2% respectively. These results differ from other intertidal flats associated with different sediment sources, hydrodynamic environments and bio influences. The results of grain size trends show that the sediments mainly transport northwestward near the sub tidal zone; but southward, southwestward and southeastward, which are related to tide regimes, local landscape, large human constructions and the biological activities.
