摘要
Abstract
This paper divides the shallow waters of the North Liaodong Bay into 12 zones, then analyzes the spatio-temporal variation of suspended sediment concentration and its transport direction, and further explores the high suspended sediment zones in the North Liaodong Bay. The study shows that; ( 1 )The wind speed of the whole sea area has significant effect on suspended sediment concentration and its diffusion range; ( 2 ) The location of high suspended sediment concentration is related to the wind direction and the tidal current direction, but is irrelevant to the wind speed; ( 3 ) In the near-shore zones the average surface suspended sediment concentration at flood tides is higher than that at ebb tides, but in the 5 ~ 10m deep-water zones,it is opposite; the main transport direction of suspended sediment is SW-NE during flood tides, and vice versa during ebb tides.关键词
