Modelling Approach

Предлагается модель летнего гидротермического режима р. Енисей в нижнем бьефе Красноярской ГЭС на основе детерминированного подхода. На теплообмен воды с окружающей средой влияют следующие физические процессы: поглощение водой прямой и рассеянной солнечной радиации; поглощение поверхностью воды тепловой инфракрасной радиации (ТИР), исходящей из атмосферы; излучение поверхностью воды ТИР; испарительный и конвективный теплообмен. Результаты моделирования сравниваются с температурными данными, полученными с гидропостов. Here we consider the summertime hydrothermal regime in a 124-km river occurring within the interval (reach) downstream of the Krasnoyarsk HPP on July 3, 2016 based on the deterministic modelling approach. The reach area is divided by 4 cross-section lines (0.5, 40, 77, 124 km) with gauging stations at the first, second and forth section lines to measure water temperature. Temperature measurements at the gauging stations are taken at time
