Abstract: The steady motion of ice compacted by the flow is considered in a straight reach of a wide rectangular channel, with the flow velocities across the river width assumed to be equal, and ice accumulations to obey the laws of mechanics of non-cohesive media. The river is assumed to be blocked at the downstream end of the reach either by a natural obstruction (e. g. ice cover, or ice jam) or an artificial one (e. g. a dyke to hold the river ice or bridge piers) which does not lead to a considerable rise in the water stage, and so does not materially affect the upstream flow conditions. The mean ice drift velocity and the maximum ice pressures are evaluated. Conditions are established governing ice movement in a river channel free of obstructions.
