HYDRODYNAMIC FEATURES OF SMALL TIDAL ESTUARIES OF THE WHITE SEA BASIN
Abstract
Application of the modern hydrometric and geodetic equipment during field works in small mesotidal estuaries of the Kyanda and Tamitsa rivers flowing into the Onega Bay of the White Sea made it possible to investigate specific features of tidal waves propagation and dynamics of reversing currents. Variations of hydraulic parameters during a tidal cycle were studied using one-dimensional flow scheme. A paradoxical hydrodynamic phenomenon of negative turbulent viscosity was recorded and its nature is investigated in context of the energy dissipation mechanism in turbulent flows under the cyclic water level fluctuations and reverse currents in tidal estuaries.
