Abstract: The existing constitutive laws used in ice dynamic models have limitations in that they can not simulate the complete range of river ice transport and jam processes. In this study, the viscous-plastic rheology is refined and extended to enable a description of the ice condition at very small or zero deformation rate. The new constitutive models are validated by comparing ice jam profiles in a straight uniform channel with that of the classical ice jam theory. Simulation of an ice event in the Upper Niagara River is also presented and validated with field data.
