Abstract

We use a deterministic approach to simulate summer hydrothermal regime of a stream. Our simple model involves calculating water temperature in a coordinate system moving with the water. The physically based estimation of water heat budget takes into account absorption of solar radiation by water surface, emission of thermal infrared radiation (TIR) by water and absorption of atmospheric TIR, as well as convective heating of water and heat loss due to evaporative processes. The proposed model is applied to simulate stable diurnal thermal regime of the Yenisei River, employing the Fourier equation for mathematical modeling. We assess the contribution of each of the physical processes into water temperature and come up with a stable temporal diurnal thermal regime for the Yenisei River.
