Typification of water bodies is an important issue in connection with their diversity. Two their categories — natural and artificial, above all, stand out. Rivers, lakes, etc belong to the first category. Reservoirs etc relate to the second.
Quantitative and qualitative characteristics of runoff for rivers are of particular importance in the study of natural water objects. The report presents the results of the allocation of anthropogenic component of the hydrochemical flow of the Ob-river in the area to the Barnaul. "Pulsating" level mode of the drainless Chany lake considered as an interesting hydrological example.
The assessment and prediction of the state of ecosystems of a number of Siberian reservoirs as artificial water bodies was carried out by means of simulation.
The assessment of the characteristics of the real Ust-Ilimsk reservoir served as the analog for forecasting of the water quality which was executed at the stage for the Boguchanskoye reservoir design.
Reproduction of the transformation biogeochemical cycles for elements limiting the development of hydrobionts made it possible to create a adaptive simulation model of the Novosibirsk reservoir. The largest metropolis of Siberia - the Novosibirsk, which uses for municipal needs the water resources of the Novosibirsk reservoir and its downstream, is now experiencing water and environmental problems.
Surplus spills are used in the water management practice to avoid a reservoir overfilling above normal headwater level. However, a mass death of zooplankton occurs when the hydrostation implements idle water discharges in summer- autumn periods. The destruction of organisms responsible for the sustainability of aquatic ecosystems all year round is concerned to environmentalists. The paper presents a model approach, the implementation of which this environmental problem can be solved.
The reported research was funded by the Russian Foundation for Basic Research and the government of Altai Krai of the Russian Federation, grant № 18-41-220002.
