Hydrological Structure of the Sheksna River Deep of the Rybinsk Reservoir and Water Quality Assessment by Biological Parameters

A. S. Litvinov, A. V. Zakonnova, and E. N. Sokolova

Peculiarities of formation and seasonal dynamics of hydrological structure of the Sheksna River Deep of the Rybinsk Reservoir are considered. The contribution of various genetic water types, including run-offs of the town of Cherepovets, to the formation of its water masses is established on the grounds of model calculations. It is shown, that the hydrological structure effects the distribution of hydrobionts in sewage disposal areas. The assessment of the contribution of Cherepovets run-offs to the change of total water salinity of the deep is given.
