Assessment of the role of reservoir morphology in parameterizing its ecological regime under extreme hydrological conditions

Аннотация

The results are presented of scenario calculations of water quality parameters and biological productivity in three areas of morphologically different types of reservoirs in the years with extreme water conditions. Three models of reservoirs with the same size and flowage are used: river-, lake-, and mixed-type reservoirs. The study is based on the morphometric parameters and bathygraphical curves from 18 stretches of the Mozhaisk Reservoir. The revealed differences in the intensity of algae bloom and anoxia in hypolimnion in the simulated reservoirs are compared with the criteria of the norm and risk of the ecological regime of the reservoirs being the sources of municipal water supply.
