- Аннотация: The phenomenon of negative flow resistance was fixed during detailed hydrometric measurements directed on investigation of flow resistance variations during tidal period. It was observed in August, 2016 in meso-tidal estuary of the Kyanda river flowing into the Onezhskaya Guba (the Bay of Onega) of the White Sea. The research was based on synchronous flow discharge and water level measurements at the boundaries of 3 km length estuarial stretch and corresponding estimations of the Saint Venant movement equation terms. The flow resistance was of negative value twice during the tidal period. The research of negative flow resistance and eddy viscosity in tidal estuaries may provide the base both for improvement of resistance parameters estimation, and for reduce of energy consumption for water movement in water management and transport projects.
