Sustainable water use of the Kuibyshev reservoir as an hydropower facility

Abstract

© 2019 IOP Publishing Ltd. Sustainable water use in a broad sense is a combination of all forms and uses of water resources that directly and indirectly affect the formation of the water fund. When operating hydropower facilities, it is necessary to comply with the requirements for the rational use and protection of water bodies. The article presents the results of the assessment of the specificity of water consumption and water disposal in the Kuibyshev reservoir within the Republic of Tajikistan, as well as the calculation and assessment of the main trends in water reservoir quality dynamics. Calculation of the index of the combinatory water pollution index during the period 2009-2017 yrs allowed to reveal a moderate tendency of its decrease within the limits of the 4th class of quality from the upper reaches to the dam of the Kuibyshev reservoir.
