Climate Resilience Planning: Modelling Multi-Functional Reservoirs under Changing Climate****

战略社区咨询公司（SCC）正在加拿大西部开发可扩展且具有成本效益的解决方案，用于有效投资气候适应能力。SCC获得了一份主要合同，评估沿博因河系统的1亿美元Treherne大坝项目的投资案例，该项目具有传统水库和大型工程湿地的特点。Treherne上游的工程湿地Pelly’s Lake被认为是一个展示多功能的水库，可以减少洪水和干旱风险、灌溉、改善水质和生物质生产，其效益成本估计在2.83到3.64之间。SCC需要一个博因河水系的多功能水文模型原型，以准确评估Treherne大坝的多功能、气候适应能力和整体系统效益。本研究将开发一个系统的综合水管理模型，以模拟所有系统组件之间的相互联系，包括阿西尼博因河和博因河以及Pelly's湖，Treherne和Stephenfield水库，并评估和优化系统中灌溉供水，减少洪涝和干旱风险以及改善水质带来的经济发展效益。本研究开发的工具将包括该水系统的综合模型，可以支持优化和设计多功能保留存储，以减轻气候变化适应所需的洪涝和干旱风险。这些工具将转交给SCC。本研究开发的结果和模型与加拿大保险局和加拿大基础设施推荐的最佳实践相一致，并且是许多其他水资源紧张的农业地区所需要的，其他加拿大技术公司也将感兴趣。

Strategic Community Consulting (SCC) is developing scalable and cost-effective solutions for efficient investments in climate resilience, in Western Canada. SCC has a major contract to evaluate the investment case for the $100M Treherne Dam project along the Boyne River system with features of both a conventional reservoir and a large engineered wetland. An engineered wetland site upstream of Treherne, Pelly's Lake, is recognized as a showcase multifunctional reservoir for flood and drought risk reduction, irrigation, water quality improvement, and biomass production with a benefit-cost estimated to range from 2.83 to 3.64. SCC needs a prototype multifunctional hydrological model of the Boyne River system to accurately evaluate the multifunctional, climate resilience, and overall system benefit of the Treherne Dam. This research will develop an integrated water management model of the system to simulate the interconnections between all system components, including Assiniboine and Boyne Rivers and Pelly's Lake, Treherne, and Stephenfield reservoirs and to evaluate and optimize the economic development benefits from irrigation water supply, flood and drought risk reduction and water quality improvements in the system. Tools developed in this research will include comprehensive models of this water system that can support optimization and design of the multifunctional retention storage for flood and drought risk mitigation needed for climate change adaptation. These tools will be transferred to SCC. Outcomes and models developed by this research are consistent with the best practice recommended by the Insurance Bureau of Canada and Infrastructure Canada and are needed for many other water-stressed agricultural regions and will be of interest for other Canadian technology firms as well.
