| 摘 要： | 本文从液体不稳定流微分方程出发,推导了河口均质潮流垂线流速分布公式,水流切力垂线分布公式以及床面阻力公式,并用实测资料作了验证,二者基本吻合。在此基础上,应用大量的实测资料统计分析,得到了反映潮汐河口床面阻力系数变化的表达式。

Study on Vertical Velocity Distribution and Bed Resistance in a Estuary |
| |
| Abstract: | Based on the basic differential equation of unsteady flow,the equations of velocity and shear stress distributions in vertical and the resistance equation for tidal flow have been dierived in this paper. These equations are verified and agreed approximately with measureddata. Finaly the espression of resistance coefficient in estuarine has been given. |
