Abstract

The features and structure of transition layers with an intermediate state of the environment, simultaneously including liquid and solid phases, during the formation and melting of the ice cover of a fresh water body are considered. Computational modeling of the dynamics of the ice cover was carried out based on the generalized formulation of the Stefan problem, taking into account the average daily values of temperature and humidity, wind speed, and solar radiation flux. The results of calculating the temperature regime and the state of the reservoir during the cold period in the presence and absence of snow cover on the ice surface are presented. The time dependences of the compressive strength of the ice cover were obtained taking into account the vertical temperature distribution
