Abstract: River ice jams can have significant impacts on water resource development in cold regions. Due to difficulties in observing the phenomena in the field, our understanding on the dynamics of ice jam formation is very limited. Numerical models, such as HEC-RAS, have been used to determine the equilibrium ice jam configuration and its backwater effect. These models were developed based on the static equilibrium of the floating surface ice mass accumulation in the jam. They cannot be used to study ice dynamics. In this paper, the DynaRICE model is validated with a set of field observed ice jam data on the Thames River (Beltaos 1988). The model is then used to study the ice jam formation dynamics in a natural river to illustrate the dynamics of ice transport and jamming processes. The study showed that the ice congestion is a result of the convergence of ice mass produced by a complex interaction of flow and ice dynamics
