Abstract: The growth of an ice cover in a reservoir or a river results from the heat budget at the surface and bottom of the ice sheet. This situation is well known as a one-dimensional Stefan problem. In this paper, the total heat flux at the air-snow interface is linearized, and is described by its equilibrium surface temperature and heat exchange coefficient. The four approximate solutions calculating the growth of ice cover are obtained by solving the heat balance equation at the lower surface of the ice cover. The influence of meteorological elements on ice thickness, equilibrium surface temperature, and heat exchange coefficient are described on the basis of the calculated and experimental results.
