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

成果是河流流速、水位和冰破碎过程之间相互作用的数值模型。目标是：(1)为流量调节器和水力发电组织提供一个模型，使他们能够管理流量释放和增加安全电力的产生，而不会有破坏河流平衡冰况的风险；(2)评估冬季条件增加的洪水风险，从而优化冬季条件下溃坝时的洪水疏散计划。研究活动包括实地数据收集、物理过程识别；算法定义;仿真灵敏度分析；水动力与冰盖模式整合；分析和测试用例应用和模型评估。实现包括与水电合作伙伴一起进行一些测试用例，以确保工具在组织内的集成。

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.
