Model studies were made to determine hydraulic characteristics of structures for protecting ships wintering in rivers under conditions similar to those observed in European and Siberian rivers (ice-cover thickness up to 1.8m. and river depth to 12m.). The experiments are described, and data are mathematically analyzed. Formulas and graphs for calculating the stresses as a function of ice-cover thickness, flow speed, and width and depth of the river are suggested. The ice pressure on protective booms in a stream wider than 30 m was found to increase 85-90% due to the friction between the lower ice surface and flowing water. The friction coefficient is proportional to the ratio of ice thickness to flow depth.
