ABSTRACT

The main components of the intra-waterbody oxygen balance of the Kiev reservoir, including atmospheric and photosynthetic aeration and biological and chemical oxygen demand, were studied in wintertime. It has been found that freezing-over, which is responsible for atmospheric and photosynthetic aeration, flowrate, and also the concentration of oxygen in the Pripyat and Dnieper rivers flowing into the reservoir, are the main factors influencing dynamics of the content of dissolved oxygen.
