Abstract
Given the observations at the section of the Ob river below the dam location of the Novosibirsk Hydropower Station, the calculations of water level dependence on water discharge and ice hole length in winter are carried out by the model of nonstationary hydrodynamic and ice-thermal processes. Some algorithm is developed that uses the dependence and allows us to determine the optimum discharge at the dam section providing the stable functioning of the river water intakes near Novosibirsk. The results of calculations are given for various values of the roughness coefficient of the lower ice cover.
