| 摘 要： | 对辐射沙洲海域东大港水道4号站位连续2个潮次的流速测量资料进行了分析、研究,拟合给出了流速垂线分布关系,并根据实际测量资料率定了该站位各时刻6个水层的浑水水流的尾流函数项表达式,这些表达式表明浑水水流的尾流函数项是相对深度和摩阻速度的函数。 |
| 关 键 词： | 辐射沙洲 潮流 垂线分布 拟合 尾流函数 |

| Abstract: | On the basis of analyzing the two tidal periods' successive survey results on the tidal current at No.4 station in the tidal channel called Dongdagang,the characters of tidal current and space distribution of current vector are further studied.The vertical distribution of current velocity is studied and the surveyed current velocity data are fitted to the relative depth.The vertical distribution relationship between velocity and relative depth is discovered.Based on the surveyed current velocity data,the remainder current functions of six water layers are calibrated by the fitting method.The remainder current function term is the function of friction velocity and relative depth. |
| Keywords: | radial sand ridges tidal current vertical distributing fitting remainder current function term |
