Kuznichenko S. Water and salt regime of the Kugurluy – Yalpug lake system in conditions of their regularity

The object of investigation is the Kugurluy – Yalpug lake system, lakes basin and Danube. The purpose of study is the scientific ground of the measures directed on maintenance of optimum water and salt regime of the lakes Kugurluy and Yalpug. The methods of investigation is the statistical analysis of temporal rows different hydrological and hydrochemical characteristics, mathematical simulation of hydrological and hydrochemical regime at the different operating conditions of reservoir. The theoretical and the practical results of researches consist in the scientific ground of the water and salt regimes of the Kugurluy – Yalpug lake system and development on their basis of recommendations relative to the further use of waters resources of reservoir. The novelty is development of mathematical model by which long-term change of mineralization of water in lakes is restored, realization of variant simulation on the set indices of water quality by hydrochemical indices. The developed recommendations and obtained results may be used for improvement of water management of the lakes Kugurluy and Yalpug. Branches of using - Statу Committee on Water Economy.
