| Résumé | The present report describes work done during 2009/2010, whish is part of a project aimed at clarifying two issues: (1) the formation of landfast ice; and (2) the influence of floe size on the drift and deformation of ice covers. The flow through converging channel is used as means to examining those two issues. The present work achieved the following: (1) Established a criterion that quantifies the mobility of ice covers as they flow through constrictions. A dimensionless relationship was found which governs the level of restriction to ice flow. (2) Tensile strength of the ice cover was introduced. The results establish the feasibility of incorporating the tensile strength in the forecasts. Moreover, the role of tensile strength on the mobility of ice through restrictions was evaluated. (3) Tests have established a feasible method for modeling the drift and deformation of individual floes. The results show qualitatively the manner in which individual flows interact as they pass through a constriction. The results form a basis for quantifying the role of floe sizes on the dynamics of ice covers. The report includes suggestions for employing the present conclusions in subsequent efforts towards achieving the ultimate objectives of the overall project. |
