Ex-typhoon Merbok slammed Western Alaska in September 2022, leading to widespread damage and disruption in numerous coastal communities. The large geographic coverage, unique co-occurrence of extreme flood and wind events, and extremeness of damage caused by this ex-typhoon have provided an opportunity to perform reconnaissance activities and determine the best pathways to enhance the resilience of communities to similar extreme events in the future. In particular, investigations in this context help with the documentation of the effects of a range of storm-driven hazards in rural communities that had rarely experienced events of this magnitude in the past. The widespread damage to the electric power network impaired the daily life of the rural communities that were not prepared for such events. In parallel, the emergency and recovery efforts were delayed due to access issues originating from damage to several roads and bridges. Thus, the test-bed afforded by the September 2022 storm in Western Alaska is expected to allow a detailed investigation of a range of research questions categorized based on the time of action associated with each. This project will enable the performance assessment of physical components of civil infrastructures, the development of data-assisted empirical relationships that capture the damageability of constructed facilities, and the identification of post-disaster recovery actions that effectively contribute to the resiliency of the impacted communities in rural regions. For this purpose, perishable damage data and recovery activities will be collected from the field for systematic studies toward enhancing resilience and establishing effective mitigation strategies for vulnerable communities. Such original information will continue to advance resilient practices in coastal regions to further reduce loss of life and property. The planned investigations will also contribute to transforming the capabilities of owners, planners, and policymakers to characterize resilience under various extreme event scenarios and determine optimal adaptation and mitigation strategies. The educational goal of this project is to train a future generation of diverse engineers who can produce innovative solutions to maintain civil infrastructures in service in the face of calamities.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.

前曼联Merbok于2022年9月猛烈抨击阿拉斯加西部，导致许多沿海社区受到广泛破坏和破坏。庞大的地理覆盖范围，极端洪水和风事件的独特同时出现以及由这一前二次典范造成的极端性，为进行侦察活动提供了机会，并确定了未来社区对类似极端事件的弹性的最佳途径。特别是，在这种情况下进行的调查有助于记录过去很少经历过这种大规模事件的农村社区一系列风暴危害的影响。电力网络对电力网络的广泛损害损害了未为此类事件做准备的农村社区的日常生活。同时，由于从损坏到几条道路和桥梁的访问问题，紧急和恢复工作被推迟了。因此，预计2022年9月在阿拉斯加西部风暴中提供的测试床有望根据与每个相关的行动时间进行详细研究对一系列研究问题进行分类。该项目将使对民用基础设施的物理组成部分进行绩效评估，建立数据辅助的经验关系，以捕捉建筑设施的损害性，以及识别后悬停后的恢复行动，这些恢复行动有效地有助于农村地区受影响社区的弹性。为此，将从该领域收集可腐烂的损害数据和恢复活动，以进行系统的研究，以增强弹性并为弱势群体建立有效的缓解策略。这种原始信息将继续推进沿海地区的弹性实践，以进一步减少生命和财产损失。计划的调查还将有助于改变所有者，规划师和决策者的能力，以在各种极端事件场景下表征弹性，并确定最佳适应和缓解策略。该项目的教育目标是培训一代多样的工程师，他们可以在面对灾难的情况下生产创新的解决方案，以维持民事基础设施的服务。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的审查标准来通过评估来获得支持的。
