///The authors analyzed surface sediment characteristics of Lingdingyang Bay in the Pearl River Estuary based on 230 bed material samples collected in December 2004. The results indicate that there are six types of bed materials in the Lingdingyang Bay, with clayey silt being the dominant type. Under the influences of runoff, tidal current, wind waves, and salty water, the bed sediments in the northern zone are the coarsest; those in the southern zone are coarse; those in the middle zone are the finest; and those in the eastern zone are a little coarser than those in the western zone. The sorting of bed sediment becomes better and better from the middle zone to both the east coast and the west coast, but the total sorting is poor. The spatial distribution and deposition characteristics of different grain-size sediments are different. The patterns of the sediment transport in the Lingdingyang Bay are very complex, but the total sediment transport trend is southwestward.
