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保护堤防系统洪水泛滥的县中。历史上服务不足和社会脆弱的社区（HUSVC）尤其处于危险之中，因为它们的暴露率很高和缓解障碍。该奖项支持一个跨学科研究项目，旨在探索气候知情的策略，以公平地适应复合危害，以应对这些挑战。该研究项目旨在确保在满足HUSVC的需求的同时，确保国家老龄堤的弹性。这些发现将有助于在当前和未来的气候条件下，有助于堤防安全性和耐用性。该项目将气候科学的进步转化为工程师和决策者易于理解的信息。该项目具有三个主要目标：确定堤防社区内的脆弱性和差异；开发将复合危害纳入工程设计和风险评估的理论框架，并根据技术，社会经济和政策因素确定公平的气候适应策略。研究人员假设在不断变化的气候下忽略了多种危害的复杂作用，低估了堤防失败的风险及其对HUSVC的不成比例影响。目的是告知在技术上合理，社会公正和经济可行的软堤防适应措施。该团队与当地的HUSVC一起了解他们的需求，优先事项和感知的风险，同时还促进了洪水风险的意识和准备。在飞行员社区中，利益相关者和社区领导者提供了重要的反馈，以完善这些措施。该项目得到了人类，灾难和建筑环境（HDBE）计划以及民事基础设施（ECI）计划（ECI）计划的工程局（ENG）工程局（ENG）的工程计划（ENG）。这项奖项反映了NSF的法定任务，反映了通过评估委员会的范围，并已被评估范围众所周知。
