Abstract
The processes of heat transfer and phase transformations in a freshwater reservoir during the cold season are considered. A non-stationary computational model applied for determining the thermal behavior of a reservoir and the ice cover dynamics is based on the numerical solution of the Stefan problem in a generalized formulation. Climatic conditions are considered in the form of dependences of the average daily values of air temperature, wind velocity, humidity and solar radiation flux. The influence of heat fluxes and snow cover height on the reservoir temperature and ice growth dynamics is analyzed.
