潮流是浅海环境动力学的重要因素之一。浅海潮流空间结构的研究,一直是海洋学和海洋工程学界共同重视的课题。现今,海洋资源(尤以石油能源)开发及海洋工程事业的迅速发展,要求更加详尽地了解潮流在不同水层的分布,以计算海了构筑物的动力响应,了解底流场形势,去设计海底管线的铺设。半个世纪以来,不少研究者对浅海潮流铅直结构进行探索,积累了不少研究成果。但是,终因难以测量流速(尤其底流速)铅直脉动的精确资料,而无法深入研究具体海区铅直动量交换的机制。迄今,实际海区三维空间潮流场的计算,只停留在将铅直湍流粘性系量取
Tidal current is one of the important factors of shallow sea environment dynamics. The research on the spatial structure of shallow tides has always been a common issue of oceanography and marine engineering. Nowadays, the development of marine resources (especially petroleum energy) and the rapid development of marine engineering require more detailed understanding of the distribution of currents in different aquifers to calculate the dynamic response of structures, understand the situation of underflow fields, and design the seabed Laying of pipelines. For half a century, many researchers have explored the vertical structure of shallow tidal currents and have accumulated many research results. However, at the end of the day, it is difficult to measure the precise information of the vertical pulsation of the flow rate (especially at the bottom flow rate), but not to study in depth the mechanism of the vertical momentum exchange in the specific sea area. So far, the calculation of the tidal current field in the real sea area in three-dimensional space only stays in the range of the vertical turbulent viscosity coefficient
