Vertical distribution character of current velocity in Dongdagang channel
东大港水道流速垂线分布探讨

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.
