This project addresses two key tensions in flood and drought mitigation: tradeoffs between minimizing flood and drought risk, and tradeoffs in the choice of where in the system to invest in risk mitigation. This project will study these tradeoffs through detailed case studies in distinct hydro-climatic and governance settings: Lake Mendocino, California and Danjiangkou Reservoir in Hubei Province, China. In both cases, water managers are exploring the use of streamflow forecasts to improve reservoir operations for flood control and water supply under changing conditions. This project will collect and analyze data on hydrology, infrastructure and decision making to study the impacts of operational changes and identify strategies that facilitate adaptation. A model will be developed to test how practices to reduce flood and drought impacts interact across scales (e.g., regional, municipal) and respond to change, in different environmental and social settings. The project team will work with decision makers to learn from their experiences and develop tools that fit their needs. The project will also provide education and training opportunities for the next-generation workforce in hydrology and water resources systems analysis through mentored research experiences and new course modules.This project will address three key questions: 1) How will a change in reservoir operations propagate through the partially-engineered, partially-evolving watershed system? 2) What characteristics of the hydrological or governance system affect this propagation? 3) What institutional design choices enable adaptive management? While the case-based models developed can address the research question in two specific contexts, the project also aims to derive generalizable knowledge about the features and processes critical to mitigating flood and drought risk as well as insights into unintended fragilities. To build theory, the project will also generate a differential equation-based socio-hydrological model of a generic reservoir and watershed system. This model will be used to explore the system-level patterns that emerge in the long-run under a range of conditions, which will enable us to build theory on the hydrological and institutional factors critical to understanding the effects of reservoir operating rule changes. In summary, this work will advance knowledge of adaptive flood and drought management in four ways: 1) illustrate the tradeoffs between flood and drought mitigation goals in reservoir operations across scales; 2) identify the processes through which reservoir operation changes propagate through the system; 3) quantify the benefits and limitations of controlling streamflow variability; and 4) demonstrate the impact of institutional design choices in detecting critical changes and facilitating response. This new knowledge will address the practical challenge of planning for higher streamflow variability, while mitigating the risk of generating unintended fragilities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目解决了洪水和减轻干旱的两个关键紧张局势：在最小化洪水和干旱风险之间的权衡，以及选择在系统中投资降低风险的位置方面的权衡。该项目将通过不同的水力气候和治理环境中的详细案例研究来研究这些权衡：加利福尼亚州的门多西诺湖和中国湖北省的丹吉安格库尔水库。在这两种情况下，水管理人员都在探索水流预测的使用，以改善在不断变化的条件下洪水控制和供水的水库操作。该项目将收集和分析有关水文，基础设施和决策的数据，以研究运营变化的影响并确定促进适应的策略。将开发一个模型，以测试如何减少洪水和干旱影响跨尺度（例如区域，市政）相互作用的实践，并在不同的环境和社会环境中对变化做出反应。项目团队将与决策者合作，从他们的经验中学习并开发适合其需求的工具。该项目还将通过指导的研究经验和新的课程模块为下一代劳动力提供教育和培训机会。该项目将解决三个关键问题：1）储层运营的变化将如何通过部分工程的部分工程，部分改进的，分析的分水果系统传播？ 2）水文或治理系统的哪些特征会影响这种传播？ 3）哪些机构设计选择可以实现自适应管理？尽管开发的基于案例的模型可以在两个特定情况下解决研究问题，但该项目还旨在获得有关减轻洪水和干旱风险至关重要的特征和过程的普遍知识，以及对意外脆弱性的见解。为了构建理论，该项目还将生成一个基于微分方程的通用储层和流域系统的社会流程模型。该模型将用于探索在一系列条件下长期出现的系统级别模式，这将使我们能够建立对了解储层操作规则变化的影响至关重要的水文和制度因素的理论。总而言之，这项工作将通过四种方式提高对自适应洪水和干旱管理的了解：1）说明跨尺度的洪水和干旱缓解目标之间的权衡； 2）确定储层操作变化在系统中传播的过程； 3）量化控制流量变异性的好处和局限性； 4）展示机构设计选择在检测关键变化和促进反应方面的影响。这些新知识将解决计划更高流量变异性的实际挑战，同时减轻产生意外脆弱性的风险。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子和更广泛影响的评估标准来通过评估来获得支持的。
