Abstract: This paper describes a mathematical model simulating initial formation and evolution of moving sheet ice along a selected river stretch. The model described here is part of the model RIVHER which simulates water temperature, heat transfer and subsequent generation or decay of various types of river ice. The model was applied to the St. Lawrence river in the course of studies on the proposed Archipel power station which will have a ten kilometer reach of open water immediately upstream from the plant. Quantities of moving sheet ice to be evacuated is one parameter of practical interest for design, but the major practical aspect is that moving sheet ice constitutes a "mobile cover" which reduces the volume of anchor ice. Comparison with measurements shows satisfactory agreement.
