海州湾及毗邻海域潮不对称性研究

Study on Tidal Asymmetry in Haizhou Bay

摘要: 外海潮波传播到近海河口海湾过程中，由于地形作用而发生变形，表现为潮汐潮流涨落潮的不对称。本文利用海州湾附近18天连续高频观测资料，分析了潮汐和潮流的不对称性，潮波向海州湾传播过程中，潮波变形较小，潮流变形较大，4个站位均为涨潮占优，本研究可为海州湾的泥沙输运、污染物迁移等研究提供参考。

Abstract: Tidal current and water level are distorted from their sinusoidal forms during propagation into coastal waters and entry into bays, which gives rise to tidal asymmetry. On the base of continuous observation data for 18 days, the characters of the tidal asymmetry are analyzed. The results show that the duration of falling tide is longer than the rising tide, which means that the flood flow is dominated. The study results can provide reference for the sediment transport and the pollutant transport in Haizhou bay.
