Impact of the Cheboksarskaya HPP water release on hydrological regimes of the Volga and estuaries of its tributaries
- Mari Technical University
Abstract
The paper presents the results of localized studies of the Volga River banks and estuary areas of its tributaries Bolshaya Kokshaga and Malaya Kokshaga, which are affected by the daily wave of water discharge in the tailrace of the Cheboksarskaya HPP. Dependences of temporal fluctuations of levels and current velocities were determined for different water area sections. The above results make it possible to draw up a mathematical model of water, alluvium and subsurface water movement, taking into account the relief features. This model is necessary to assess the effectiveness and environmental safety of measures aimed at the reconstruction of the territory used for recreational purposes.
