摘　　要：总结了在水流加减速作用、水流密度和悬沙浓度造成的水流分层、地形变化、风、波浪、底沙等因素影响下国内外河口海岸潮流速分布研究现状。分析了现有潮流速分布模式及修正模式存在的问题,指出潮汐水流垂向结构的研究关键是潮流剪切应力垂线分布公式的合理性;对潮流速分布模式进行了研究展望。The research status of the effects of flow, layer phenomena caused by water density and suspended sediment concentration, topographical variation, wind, waves, and bottom sediment on the tidal velocity profile in an estuary and along the coast are summarized. The distribution patterns of tidal velocity and its modification are studied. It is pointed out that the reasonableness of the shear stress vertical distribution formula is the key problem in the study of the vertical structure of tidal currents. The research prospects for tidal velocity profiles are discussed.
