On the profile of tidal currents in the northern Adriatic

Abstract

        Homogeneous vertical eddy viscosity coefficient is assu­med for the tidal current in the northern Adriatic. The order of magnitude of this eddy viscosity coefficient is stu­died. The results were obtained comparins the measured current profiles with the profiles obtained from the assu­med hydrodynamical model. The order of magnitude of the vertical eddy viscosity coefficient of 100 cm²/s seems to be, in general, acceptable independently of season or position. The data do not demonstrate the existence of a separate bottom turbulent layer characteristic for low viscosity or supression of negative rotary components characteristic for hish viscosity.
