摘要
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。
The characteristics of the tidal current in the coastal zone from Qingdao to Shijiusuo arc analysed. The actual data show that the tidal current is of typical alternating current with obvious asymmetry and large vertical variations. It is pointed that the asymmetry is due to residual current and tidal constituent current The change of the asymmetry with the variation of the residual and tidal current and the characteristics of the vertical gradient of the tidal current are discussed. Also disscussed is the influence of the asymmetry and the vertical gradient on the sand movement and pollution diffusion in the zone.
