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，美国政府正出资在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平原有管理的撤退的科学理解，包括它们对不同类型社区的影响。研究结果为决策者、洪泛区管理者和社区领袖提供了在未来使洪水适应在社会和管理上更成功所需的最先进的知识。该项目调查了全国数万户家庭，他们已经离开、留下来，并进入了联邦政府有管理的撤退政策目标的社区。该项目利用新的数据来源来跟踪参与者和非参与者随着时间的推移往返于目标为有管理的撤退的社区的居住轨迹。资料来源将包括关于居住历史的个人数据，关于未来洪水风险的地址级别数据，以及纵向家庭调查和访谈数据。这项研究还考虑了家庭所在的不同类型的社区。结果有助于理解作为洪水适应形式的住宅流动性，以及如何为面临日益增加的洪水风险的不同人口管理撤退。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。

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.
