Adaptation to minimize the joint impacts of climate change and the management of hydraulic infrastructures on fish and fish habitat

在气候变化的背景下，管理水库下游的放水以维持环境流量的工作正变得越来越复杂，需要更好的预测和决策工具。本提案旨在获取新知识，开发/改进气候变化背景下的水库 ** 管理工具，以减轻水温 ** 可能升高对鱼类的影响。该方法基于三个子组成部分：1）改进和调整水文，水力和水温模型，以适应水库管理的背景。2)获得关于Nechako系统中存在的三种重要鱼类的生理和温度要求的新的关键知识。3)使用气候变化情景来预测水库放水管理中可能需要的潜在变化。对加拿大 ** 工业的好处包括将从加拿大西部一个重要的受管理流域 ** 水温要求的首次多物种研究中获得的见解，改进水流和水温 ** 管理的建模工具，以及培训具有跨学科经验的高素质人员。

In the context of climate change, the management of water releases downstream of reservoirs to maintain**environmental flows is becoming more complex and better tools are required for forecasting and**decision-making. This proposal aims at acquiring new knowledge and developing/improving tools for reservoir**management in the context of climate change, in order to mitigate the impacts of potential increased water**temperature on fish. The approach is based on three sub-components: 1) Improve and adapt hydrological,**hydraulic and water temperature models to the context of reservoir management. 2) Acquiring new key**knowledge on the physiology and temperature requirements of three important fish species that are present in**the Nechako system, where this study is taking place. 3) Use climate change scenarios to anticipate potential**changes that may be required in the management of reservoir water releases. The benefits for the Canadian**industry include insights that will be gained from a first multi-species study of water temperature requirements**in an important managed watershed in Western Canada, improved modelling tools for flow and water**temperature management and training of highly qualified personnel with cross-disciplinary experience.
