CLIMA/Collaborative Research: Equitable Adaptive Strategies for Flood Protection Infrastructure under Current and Future Compound Hazards

超过三分之二的美国人口居住在有防洪堤系统保护的县里。历史上服务不足和社会弱势社区（husvc）由于其高暴露率和缓解障碍而特别面临风险。该奖项支持一个跨学科研究项目，该项目旨在探索气候信息战略，以公平适应复合灾害下的堤坝，以应对这些挑战。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防在当前和未来气候条件下的安全性和耐久性。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：确定被淹社区内的脆弱性和差异；发展将复合危害纳入工程设计和风险评估的理论框架，并基于技术、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破裂的风险及其对husvc的不成比例的影响。目标是提供软性和硬性堤防适应措施，这些措施在技术上是合理的，在社会上是公正的，在经济上是可行的。该团队与当地的husvc合作，了解他们的需求、优先事项和可感知的风险，同时提高洪水风险意识和准备工作。在试点社区中，利益相关者和社区领导人提供重要反馈，以完善这些措施。该项目得到了工程局土木、机械和制造创新司（CMMI）的人类、灾害和建筑环境（HDBE）项目和土木基础设施工程（ECI）项目的支持。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
