Abstract: Empirical methods have been used for calculating the flow resistance of river ice jams. The friction coefficient or Manning’s coefficient has been suggested to vary linearly with the jam thickness or the ratio of jam thickness to flow depth. This study exams the flow resistance due to the seepage flow through the jam and the resistance due to the shear stress on the undersurface of the jam. It shows that the resistance due to the seepage flow is an important part of the flow resistance, especially for the portion of the jam where the thickness is very large, such as the part near the jam toe.
