Abstract: The stream channel is constricted when spur dikes and bridge piers are placed in the waterway. In northern climates, temperatures are sufficiently low to cause an ice cover to form for a considerable part of the year. This paper deals with the study of the effect of an ice cover on the erosion of the river channel which has been reduced in width by the presence of engineering structures. Analytical and experimental methods were used to derive the dimensionless functions. Polyethylene sheets and pellets, which have a specific gravity very close to natural ice, have been used to simulate the ice cover and ice flows with quartz sand as the bed material. The results would be useful in design.
