STUDY RESULTS ON OPTIMIZATION OF HYDROBIOLOGICAL INDICATORS OF SPRING ECOLOGICAL REPRODUCTIVE RELEASES FROM DNIESTER RESERVOIR
Posted on 31.03.2021
Along with creation of three HPS dams on the Dniester River, the flow of water into the middle and lower reaches of the Dniester River became regulated by the operation of the hydropower station. Spring is the most critical period for the reproduction of living organisms, therefore the so-called spring ecological reproductive releases – a coordinated and scientifically substantiated discharge of water from the Dniester HPS, simulating a spring flood – is crucial for the normal functioning of the Dniester ecosystems, which, among other things, provides enormous benefits for humans. However, it is a serious and difficult task to consider all the aspects of the release, its often contradictory and mutually exclusive objectives, requirements and restrictions.
The GEF Dniester project team presents the “Express-study of hydrobiological indicators to optimize the release regimes from the Dniester reservoir” (in Russian). This study together with the “Analysis of the goals, limitations, and opportunities for optimizing the regime of spring ecological reproductive release from the Dniester reservoir” will help the specialists who take part in the coordination of the volume of water (discharge) from the Dniester reservoir in spring to answer the questions of “when”, “how much” and “for which species” it is optimal to make such discharges.
The analysis was carried out within the framework of the GEF Dniester project at the request of the governments of the Republic of Moldova and Ukraine, with the involvement of a wide range of specialists.
