涨潮

Blocked by the scheduled project, the tidal current near the coast will move around the project. 4. Changes of SSC before and after the project The general characteristics of the SSC both before and after the scheduled project are as the following: the SSC is lower in the waters of the project ranging from 11 mg/L to 19 mg/L; the SSC isolines are generally parallel to the isobaths, decreasing towards the coast; the SSC in flood tide is higher than that in ebb tide, so are high tide and spring tide than low tide and neap tide, respectively.

4工程前后悬沙量变化工程前后悬沙分布的基本规律：在工程海域，悬沙量均保持为较低值，大致为11～19mg/L；悬沙等值线基本平行于等深线，随深度的减小浓度减小，一般到近岸区达到最低；悬沙量的日周期性变化规律明显，悬沙量涨潮时大于落潮时，高潮时大于低潮时，大潮时大于小潮时。

Results show that floes' VC and D at the surface water were closely related to current velocity; and the peaks of VC lag those of the current velocity. The lag variation during ebb and flood tides is 10-30min and 30-50 min, respectively. Current velocity at 50 cm/s is a turning point of D vs. vertical average current velocity, before the point, Dm increases with current velocity, and decreases after the point. Similarly, VC at 75μl/L becomes a critical point in the surface water, below the point, D increases with VC, and above the point, D stabilizes.Δp is D dependent, larger floes have much lower Δp than smaller floes. Both D and Δp of floes affect ω. In the surface water during spring tide and neap tide, a power exponent relationship exists between Δp and D, and ω and D.

研究表明：①长江口徐六泾表层絮凝体体积浓度主要受水流流速影响，再悬浮现象明显，体积浓度过程线滞后流速过程线，落潮期间滞后10-30min，涨潮则滞后30-50min；②小于一定流速时絮凝体平均粒径随流速增大而增大，大于一定流速时絮凝体平均粒径则随流速增大而减小，徐六泾夫、小潮表层絮凝体在50cm/s的垂线平均流速时出现平均粒径与垂线平均流速关系的转折；③徐六注大、小潮表层絮凝体平均粒径在体积浓度75μl/L时出现平均粒径与体积浓度关系的转折，体积浓度小于75μl/L时粒径随体积浓度增加而增大，超过75μl/L时粒径随体积浓度的增加变化不明显；④絮凝体有效密度由粒径大小控制，粒径大，有效密度小，反之亦然，粒径和有效密度共同决定絮凝体静水沉速，有效密度和沉速与平均粒径之间均存在良好的幂指数关系。
