Abstract: Basic ice processes occurring in the period of the first appearance of ice in rivers are freeze-up and ice run. Ice run is correlated with the occurrence of skim ice, brash ice, frazil and slush ice. The basic types of ice run are skim ice run and run of frazil. In this paper these basic types are discussed. Using new findings about the freezing-up of the water surface by a sheet ice, mathematically formulated conditions are derived which demarcate the formation of frazil and skim ice. The validity of the theory is confirmed by the results of observations and measurements on rivers with various riverbed roughness.
