MCA: Enhancing the Resilience of Interdependent Natural-Built Infrastructure Systems in Urbanized Coastal River Floodplains with Geomorphological Solutions

该项目旨在改善居住在地势低洼、城市化的沿海河流泛滥平原上的易受洪水影响的社区的复原力。许多居住在沿海县的居民可能会从这一项目中受益，这些居民约占美国人口的40%。该项目将研究自然和已建基础设施系统之间的相互依存关系如何影响洪水风险，以及如何利用自然栖息地来减轻洪水影响。产生的知识将加强决策者最大限度地提高国家安全、公共安全、生活质量和保护自然栖息地的能力。该项目将扩大STEM研究、教育和劳动力的参与，推进一项基于融合科学和创新、指导、科学交流的研究计划，并创造多样化、公平和包容的环境。该项目通过共同创建对低洼、城市化的沿海河流泛滥平原综合自然建造基础设施造成的洪灾破坏的更深入理解，推进抗洪能力的概念和方法框架。该项目采用融合科学的方法，整合了地貌学和交通工程领域的学科文化、理论、方法和数据。该项目将产生关于地貌网络、地貌网络与已建基础设施网络之间的相互依存关系、这些相互依存关系对洪水引起的连锁故障的影响以及地貌生境作为基于自然的解决办法的潜力的基本知识。所产生的知识和工具将允许观察、理解和探索洪水期间自然建造的基础设施相互作用的潜在轨迹，并加强在维护和改善自然生境的同时缓解洪水风险和影响的能力。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This project aims to improve the resilience of flood-vulnerable communities inhabiting low-lying, urbanized coastal river floodplains. Many residents belonging to approximately 40% of the U.S. population, who are living in coastal counties, may benefit from this project. The project will examine how the interdependencies among natural and built infrastructure systems influence flood risk and how natural habitats can be utilized to mitigate flood impacts. The knowledge generated will strengthen the ability of decision-makers to maximize national security, public safety, the quality of life, and the protection of natural habitats. The project will broaden the participation in STEM research, education, and workforce by advancing a research program founded on convergence science and innovation, mentoring, science communication, and creating diverse, equitable, and inclusive environments.This project advances the conceptual and methodological framework for flood resilience by co-creating a deeper understanding of flooding-induced disruptions on the integrated natural-built infrastructure of low-lying, urbanized coastal river floodplains. The project adopts a convergence science approach that integrates disciplinary cultures, theories, methods, and data from the fields of geomorphology and transportation engineering. The project will generate fundamental knowledge on geomorphological networks, interdependencies between geomorphological networks and built infrastructure networks, the impacts of these interdependencies on cascading failures from floods, and the potential of geomorphological habitats as nature-based solutions. The knowledge and tools generated will allow for observing, understanding, and exploring the potential trajectories of natural-built infrastructure interactions during floods and strengthen the ability to mitigate flood risks and impacts while maintaining and enhancing natural habitats.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.
