本文对青岛—石臼所沿岸潮流特征进行了分析。实际观测资料表明,这一带潮流具有典型的往复流性质,并有较明显的不对称性和较大的垂直变化。文中指出涨落潮流不对称性是由于余流和分潮流影响的结果。讨论了不对称性随余流和分潮流的变化和潮流垂直梯度的特征。不对称和垂直梯度对泥沙运动和污染扩散的影响在文中也作了阐述。
In this paper, the tidal current characteristics along Qingdao-Shijiu are analyzed. The observed data show that the tidal current has the characteristics of typical reciprocating flow with obvious asymmetry and large vertical variation. The article points out that the asymmetry of fluctuation trend is the result of the influence of residual currents and sub-currents. The variation of asymmetry with residual current and sub-current and the vertical gradient of power flow are discussed. The effect of asymmetry and vertical gradient on sediment movement and pollution spread is also elaborated in the article.
