Abstract: A two-dimensional model for simulating river ice transport and jamming is developed. The model considers the dynamics of surface ice transport in the river coupled with the hydrodynamics of the flow. The effects of seepage flow, undercover erosion, ice boom and other hydraulic structures are considered. The model is verified with analytical solution for an idealized ice jam, and calibrated to an ice jam that progressed up the lower Missouri River during January 1977. The model is then used to simulate ice transport and ice jam at the Mississippi-Missouri confluence. The results shown that the two-dimensional ice dynamic model can accurately simulate dynamic ice transport and ice jam processes in this area. The model can be used as an efficient tool to study potential strategies to alleviate ice jam problems.
