潮流是一种非定常、非均匀的周期性运动，具有明显的加减速过程，特别是在沿海浅水水域。许多研究表明，潮流雷诺应力的垂直分布偏离了线性分布。潮流雷诺应力的抛物线分布是由Song等人提出的。(2009)。该模型虽然与现场观测和室内试验资料吻合较好，但其潮流雷诺应力的截断级数展开式较低，且对其分布的描述不是很全面。通过引入潮流运动方程，改进了Song等人建立的抛物线分布。(2009)，提出了潮流雷诺应力的立方分布。实验数据(Anwar and Atkins，1980)和鲍登等人(Bowden and Fairbairn，1952；Bowden et al.，1959；Rippeth et al.，2002)的数值模型结果与Kuo等人的数值模型结果吻合较好。(1996)，并与潮流雷诺应力的抛物线分布进行了比较。结果表明，这种三次分布不仅优于抛物线分布，而且能更好地反映雷诺应力随潮流加速向下偏离线性分布、随潮流减速向上偏离直线分布的基本特征，为进一步研究潮流流速分布奠定了基础。
Tidal flow is a periodic movement of unsteady and non-uniform, which has acceleration and deceleration process obviously, especially in coastal shallow waters. Many researches show that vertical distribution of tidal flow Reynolds stress deviated from linear distribution. The parabolic distribution of the tidal flow Reynolds stress was proposed by Song et al. (2009). Although the model fills better with field observations and indoor experimental data, it has the lower truncated series expansion of tidal flow Reynolds stress, and the description of the distribution is not very comprehensive. By introducing the motion equation of tidal flow and improving the parabolic distribution established by Song et al. (2009), the cubic distribution of the tidal flow Reynolds stress is proposed. The cubic distribution is verified well by field data (Bowden and Fairbairn, 1952; Bowden et al., 1959; Rippeth et al., 2002) and experimental data (Anwar and Atkins, 1980), is consistent with the numerical model results of Kuo et al. (1996), and is compared with the parabolic distribution of the tidal flow Reynolds stress. It is shown that this cubic distribution is not only better than the parabolic distribution, but also can better reflect the basic features of Reynolds stress deviating from linear distribution downward with the tidal flow acceleration and upward with the tidal flow deceleration, for the foundation of further study on the velocity profile of tidal flow.
