ASSESSMENT OF THE EFFECT OF AUTUMN-WINTER RIVER LOW FLOW ON THE OPERATION OF A RESERVOIR WITH SEASONAL REGULATION

Statistical analysis of seasonal runoff variability has been carried out for the low-flow winter period on Upper Ob River. The results were used for simulating the water balance of Novosibirsk reservoir in the autumn-winter period under the hydrological conditions observed since 1894 during the period of 108 years including those with of extremely low winter runoff.
