A unified river ice breakup model - Un modèle cryo-fluvial compréhensif de la débâcle

可交付成果是河流流量、水位和冰层破裂过程之间相互作用的数值模型。其目标是(1)为流量调节器和水电组织提供一个模型，使他们能够管理流量释放并增加安全发电量，而不会破坏河流上的平衡冰情；(2)评估冬季条件导致的洪水风险增加，从而在冬季条件下发生溃坝时优化洪水疏散计划。研究活动包括从实地收集数据、确定物理过程、确定算法、模拟敏感性分析、水动力和冰盖模型集成、以及分析和测试案例应用和模型评估。实施包括与水电合作伙伴合作进行一些测试用例，以确保组织内的工具集成。

The deliverable is a numerical model of the interplay between river flow rates, levels and ice breakup processes. The objectives are to (1) provide flow regulators and hydro-electric organisations a model that would enable them to mange flow releases and increase the generation of safe electricity without risking to disrupt equilibrium ice conditions on the river; (2) to assess increased flood risks due to winter conditions and thereby optimize flood evacuation plans in the event of a dam break during winter conditions. Research activities include data gathering from the field, physical process identification; algorithm definition; simulation sensitivity analysis; hydrodynamic and ice cover model integration; and analytical and test case application and model assessment. Implementation includes working with a hydro-electric partner for some test cases to ensure tool integration within the organisation.
