【摘要】：以2015年5月10—19日(小潮至大潮)在虾峙门航道口门附近水域的定点水文测验资料为支撑,利用调和分析、数理统计及机制分解等方法研究该水域水动力特征及水体输移机制,研究结果表明:虾峙门航道口门附近潮汐性质为中等强度的非正规半日浅海潮;潮波特性近似于典型前进波特性;潮流运动形式处于往复流向旋转流的过渡区,呈顺时针方向旋转;潮流流速垂向分布表现为由表至底减小,最大流速出现在表层或0.2H层;垂线平均流速表现为大潮小潮中潮;该水域涨潮流占主导优势,且小潮至大潮优势流逐渐减小。水体输移动力以欧拉余流为主,同样表现为大潮小潮中潮。
[Abstract]:Based on the fixed-point hydrological data from May 10-19, 2015 (from low tide to spring tide) in the waters near the mouth of the Shrimp Shimen Waterway, and using harmonic analysis, The hydrodynamic characteristics and transport mechanism of the water are studied by mathematical statistics and mechanism decomposition. The results show that the tidal property near the mouth of the Shrimp Shimen Channel is an informal semi-diurnal shallow tide of moderate strength; The characteristic of tidal wave is similar to that of typical forward wave, the form of tidal current is in the transition region of reciprocating flow to rotating flow, rotating clockwise, the vertical distribution of tidal current velocity decreases from top to bottom, and the maximum velocity appears in surface layer or 0.2H layer. The average flow velocity of the vertical line is the middle tide of the spring tide, and the dominant tidal current is dominant, and the dominant current from the low tide to the spring tide decreases gradually. Euler residual current is the main transport force of the water body, and it is also shown as the tide in the middle tide.
