总结
通过各种方法对流经梅奈海峡的水流进行的观测都表明，在半日潮期间，水向西南方向的残余输送。这种运输的规模估计表明，在一个半日潮期间，它的数量级为3 000万立方米，相当于西南方向的平均剩余速度约为15厘米/秒。这种剩余流的可能原因被认为是，它表明，计算的潮流在一个短通道连接两个盆地具有相同的平均水位，但不同的潮差和相位，其中的潮高遵循精确的正弦曲线可能会表现出类似的功能时，摩擦项包括在运动方程中，观察到的梅奈海峡。
Summary
Observations of the flow of water through the Menai Straits by various methods have all indicated a residual transport of water towards the south-west during a semi-diurnal tidal period. Estimates of the magnitude of this transport indicate that it is of the order of 30 million m3 during one semi-diurnal tidal period, corresponding to an average residual velocity of approximately 15 cm/s to the south-west. Possible causes of this residual flow are considered, and it is shown that the computed tidal flow in a short channel connecting two basins with the same mean water level but different tidal ranges and phases and in which the tidal heights follow precise sine curves may exhibit similar features, when a friction term is included in the equation of motion, to those observed in the Menai Straits.
