| Résumé | This paper presents predictions of the flow of ice in wedge-shaped converging channels. Such flows are encountered in the relatively constricted waters of the Canadian Arctic Archipelago. Ridging, lead opening patterns, development of high-pressure area, and arch formation are some of the processes present during ice flow through converging channels. An idealized geometry was used in the testing to represent many of the areas typical in the Canadian Arctic Archipelago. The results show the ice cover flow, distribution of stresses, ice thickness, area coverage, ridging, and arch formation at the constricted exit of the channel. The effects of thermodynamic growth and melt are neglected as the forecasts cover durations of only few days. |
