Abstract:

The research project is the continuation of earlier studies and it is based on the hypothesis that frazil is formed if the water temperature t sub v 0 C, the temperature on the water surface t sub h -0.15 C, and 3 the cross- sectional water velocity v 0,067MC to the 0.305 power R to the 0.5 power, where C Chezy coefficient, M 0.7C6, R hydraulic radius. The object of the research project is to verify the mathematically formulated conditions and to establish a theory of frazil and skim ice formation.
