Description
Summary:Because the formation and breakup of ice in rivers, as well as the duration and thickness of ice, depend mainly on climatic and weather conditions in a given area, the short-term forecasting of the phenomena is based on data gathered by weather observation stations. The main factors determining the thermal exchange of water in rivers, its general and specific trends and the prospects of their calculation are analyzed. Formulas characterizing the relationship between the water and air temperature, the significance of latent heat at freezing and melting, the quantity of heat in water, the velocity and direction of flow and other aspects affecting the formation, duration and breakup of ice are derived.
