Summary A technique is developed for calculating the distribution with depth of current and shearing stress in tidal estuaries. The effect of turbulence is introduced by a coefficient of eddy viscosity which is a prescribed function of the depth coordinate, and the predictions are compared with observation and existing theory. Using parameters representative of the Humber estuary, the resultant current profiles are found to be in reasonable agreement with recent measurements. The friction coefficient k (used in the Lorentz linearization of the quadratic friction law) has a value consistent with that determined by other methods. with an appendix by
