Abstract: The change of velocity distribution in the cross-section of a freezing river is discussed. Field data showing such a change in velocity distribution are shown. The loading of frazil ice in an ice-covered stream significantly increases the boundary shear and greatly affects the magnitude and distribution of the velocity of the flowing water. Field data showed that the presence of an ice cover and a high loading of frazil ice can easily double the maximum velocity of an open channel flow for the same rate of discharge. Velocity distribution equations for water flow under an ice cover with a high, or a low, frazil ice loading are developed and were qualitatively verified by field data.
