The effect of the external water cycle on certain water quality parameters of the Novosibirsk Reservoir in different water-content years
AbstractThe work describes the analysis of the influence of one of the most important hydrological factors characterizing the hydrological and hydrochemical regime of the Novosibirsk Reservoir, external water exchange, on certain water quality parameters of the reservoir for years of various water content (the extremely low-water year of 2012, the medium-water year of 2009, and high-water year of 2013). Daily water cycle factors were used for the Novosibirsk Reservoir for the first time. To investigate the dependence of chemical characteristics on the water quality on the water cycle factors, daily water cycle coefficients were calculated for specific dates, on which water samples for chemical analysis were taken. The strongest statistically significant correlations between water exchange coefficients and some chemical ingredients were obtained for the high-water year. We confirm the conclusion that in high-water years the water quality in the reservoir is more dependent on the hydrological characteristics, and in low-water years it is mainly determined by intra-water processes.
