Collaborative Research: Urban Flooding and Residential Adaptation

在所有自然灾害中，洪水对美国人口的经济和社会影响最大，而且其影响随着时间的推移而增加。作为回应，美国政府正在资助全国各地的洪泛区自愿购买房屋，将人们和房屋从全国最容易发生洪水的地区转移出去。该项目促进了对美国洪泛区管理撤退的科学理解，包括其对不同类型社区的影响。结果提供决策者，洪泛区管理者和社区领导人与国家的最先进的知识，需要使洪水适应更多的社会和行政successful.This项目调查了全国成千上万的家庭谁退出，停留，进入社区的目标由联邦政府的管理撤退的政策。该项目利用新的数据来源来跟踪参与者和非参与者的居住轨迹，并随着时间的推移从有管理的撤退的目标社区。资料来源将包括个人层面的居住历史数据，地址层面的未来洪水风险数据，以及纵向家庭调查和访谈数据。这项研究还说明了家庭所处的不同类型的社区。研究结果有助于理解住宅流动性作为一种洪水适应形式，以及如何管理撤退不同的人口面临日益增加的洪水风险展开。该奖项反映了NSF的法定使命，并已被认为是值得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的支持。

Of all natural hazards, flooding exerts the greatest economic and social impacts on the US population, and its impacts have increased over time. In response, the US government is funding the voluntary acquisition of homes in floodplains across the country, removing people and homes from the nation’s most flood-prone areas. This project advances scientific understanding of managed retreat from American floodplains, including their impacts on different types of communities. Results provide decisionmakers, floodplain managers, and community leaders with state-of-the-art knowledge needed to make flood adaption more socially and administratively successful in the future.This project investigates tens of thousands of households nationwide who have exited, stayed, and entered neighborhoods targeted by the federal government’s policy of managed retreat. The project leverages novel sources of data to follow the residential trajectories of participants and non-participants to and from neighborhoods targeted for managed retreat over time. Sources will include individual-level data on residential histories, address-level data on future flood risks, and longitudinal household survey and interview data. The study also accounts for the different types of communities in which households are embedded. Results contribute to understanding of residential mobility as a form of flood adaptation and how managed retreat unfolds differently for different populations facing increasing flood risks.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.
