The influence of hydrological and meteorological factors on the water quality of the Novosibirsk reservoir in the years of mean water content

Abstract

The influence of hydrological and meteorological factors (water temperature, precipitation, intensity of external water exchange, water inflow into the reservoir, discharge to the downstream, water level, reservoir volume) on the chemical composition of water (content of dissolved oxygen, suspended solids, nitrates, nitrites, compounds containing ammonium nitrogen, sulfates, chlorides, phosphates, a number of organic substances and heavy metals) of Novosibirsk Reservoir in the mean-water years was analyzed. The period of reservoir filling in spring and the period of water level standing at the normal maximum operating level in summer were investigated as the times most important for water quality and biota development in the reservoir.
