Analiza influenței complexului hidroenergetic nistrean asupra regimului hidrologic al fl. Nistru [Articol]

Abstract

The purpose of this paper is to study the influence of the Dnestrovsk and Dubăsari Hydropower Complex (HC) on the hydrological regime of the Dniester River. The researches were carried out by the method of comparing the hydrological regime (multiannual values of water flows and their temporary trend) of the Dniester river until and after the construction of the Dnestrovsk and Dubăsari HC for all characteristic periods. The research results demonstrate that the Dnestrovsk HC in complex/individually with the Dubăsari HC did not and do not have a negative impact on the trends in the formation of the hydrological regime of the Dniester river. It is necessary to change the data string that is currently used (1885-2022) with another data string (1956-present), because downstream of the HC we no longer have a completely natural data string. Taking into account the dangerous natural and anthropogenic hydrological situations that are formed on the Dniester River and the importance of the water supply of the Republic of Moldova, it is necessary to develop a strategic plan regarding the efficiency of the management of surface water resources, which would take into account the need to interconnect the resources of surface water of the Danube-Prut hydrographic basin with those of the Dniester hydrographic district. In this way, the risk that threatens the water supply of the Republic of Moldova would be greatly reduced.
