AB - A summertime hydrothermal regime of the Yenisei River downstream of the  Krasnoyarsk hydroelectric power plant is modeled based on a deterministic  approach. To that end, the Fourier equation is used and the following  physical processes contributing to the heat exchange between water and the  surroundings are taken into consideration: absorption of direct and  scattered solar radiation by water, absorption of downwelling thermal  infrared radiation from the atmosphere by water surface, thermal infrared  radiation back from the water surface, convection of heat and heat loss due  to evaporation of water. A clear-skies river thermal regime under no wind is  studied in a 124-km stream reach below the power plant and the obtained  results are compared against temperatures recorded at gauging stations.
