Over two-thirds of the American population lives in counties protected against flooding by the levee system. Historically underserved and socially vulnerable communities (HUSVCs) are particularly at risk due to their high exposure and barriers to mitigation. This award supports a transdisciplinary research project to explore climate-informed strategies for equitable adaptation of levees under compound hazards to address these challenges. The research project aims to ensure the resilience of the nation's aging levees while meeting the needs of HUSVCs. The findings will contribute to levee safety and durability subject to the current and future climate conditions. The project translates advances in climate science and modeling into easily understandable information for engineers and decision-makers.The project has three main objectives: identifying vulnerabilities and disparities within leveed communities; developing theoretical frameworks integrating compound hazards into engineering design and risk assessment, and determining equitable climate adaptation strategies based on technical, socioeconomic, and policy factors. The researchers hypothesize that neglecting the compounding effects of multiple hazards in a changing climate underestimates the risk of levee failure and its disproportionate effect on HUSVCs. The goal is to inform both soft and hard levee adaptation measures that are technically sound, socially just, and economically feasible. The team engages local HUSVCs to understand their needs, priorities, and perceived risks, while also promoting flood risk awareness and preparation. In the pilot communities, stakeholders and community leaders provide important feedback to refine these measures. This project is supported by the Humans, Disasters, and the Built Environment (HDBE) Program and the Engineering for Civil Infrastructure (ECI) Program of the Division of Civil, Mechanical and Manufacturing Innovation (CMMI) of the Directorate for Engineering (ENG).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.

超过三分之二的美国人口生活在防洪堤系统保护的县。历史上服务不足和社会弱势社区（HUSVC）因其高风险和缓解障碍而面临特别大的风险。该奖项支持一个跨学科的研究项目，以探索气候知情的战略，以应对这些挑战，在复合灾害下公平地适应堤坝。该研究项目旨在确保国家老化堤坝的弹性，同时满足HUSVC的需求。研究结果将有助于堤坝的安全性和耐久性受当前和未来的气候条件。该项目将气候科学和建模方面的进展转化为工程师和决策者易于理解的信息，该项目有三个主要目标：识别堤坝社区内的脆弱性和差异;开发将复合灾害纳入工程设计和风险评估的理论框架;以及基于技术，社会经济和政策因素确定公平的气候适应战略。研究人员假设，忽视气候变化中多种灾害的复合效应低估了堤坝失效的风险及其对HUSVC的不成比例的影响。其目标是为技术上合理、社会公正和经济上可行的软堤坝和硬堤坝适应措施提供信息。该团队让当地的HUSVC了解他们的需求，优先事项和感知的风险，同时也促进洪水风险意识和准备。在试点社区，利益攸关方和社区领导人为完善这些措施提供了重要反馈。该项目得到了工程理事会（ENG）土木、机械和制造创新部（CMMI）的人类、灾害和建筑环境（HDBE）计划和土木基础设施工程（ECI）计划的支持。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
