Abstract: In this paper an unsteady flow model for rivers with ice cover is developed and applied to the St. Lawrence River. The model is capable of providing a continuous simulation of flow and ice conditions in a river network during a winter season. The flow condition is determined by the solution of one-dimensional equations of motion for unsteady river flows with ice covers using an implicit finite difference scheme. Variations of hydraulic resistance of the ice cover are described by an empirical simulation model. Growth and decay of ice cover thickness are simulated by a modified degree-day model. The initial thickness of ice cover is determined by existing ice jam theories.
