CHARACTERS OF SEDIMENT DISTRIBUTION AND CONTROLLING FACTORS AT THE WHITE BEACH AND ITS ADJACENT AREA OF SHANDONG PENINSULA

From granularity analysis of surface sediment at the White beach and its adjacent area of Shandong Peninsula, together with geological and hydrological data, the effect of coast shape on sediment grain size has been discussed. The sediments are mainly clayey silt and sandy silt in the studied area. There is a S-shape distribution zone of clayey silt from northeast to southwest by Gulong Headland. Sediment gradually changes from sand to silt around Xiandao Bay area. The main hydrodynamic forces of sediment transport are tide and wave. The headland affectes the distribution of sediment grain size. Trend analysis shows that the sediment has a headland gathering transport trends in the whole area.
