The Natural Hazards Engineering Research Infrastructure (NHERI) is supported by the National Science Foundation (NSF) as a distributed, multi-user national facility to provide the natural hazards engineering research community with access to research infrastructure that includes earthquake and wind engineering experimental facilities, cyberinfrastructure (CI), computational modeling and simulation tools, high performance computing resources, and research data, as well as education and community outreach activities. Originally funded under program solicitations NSF 14-605 and NSF 15-598, NHERI has operated since 2015 through separate, but coordinated, five-year research infrastructure awards for a Network Coordination Office, CI, Computational Modeling and Simulation Center, and Experimental Facilities, including a post-disaster, rapid response research facility. Information about NHERI resources is available at the NHERI web portal (https://www.DesignSafe-ci.org). Awards made for NHERI contribute to NSF's role in the National Earthquake Hazards Reduction Program (NEHRP) and the National Windstorm Impact Reduction Program (NWIRP). NHERI Experimental Facilities will provide access to their experimental resources, user services, and data management infrastructure for NSF-supported research and education awards. This award will renew the NHERI Experimental Facility at Oregon State University from January 1, 2021, to September 30, 2025. Through this award, Oregon State University will continue to maintain, operate, and enhance the Large Wave Flume and Directional Wave Basin to provide access to experimental equipment, instrumentation, and technical support to enable research to mitigate the impact of natural hazards, such as coastal surge and waves and tsunamis, on the nation’s civil infrastructure and communities. Consistent with the grand research challenges in natural hazards engineering, as outlined in the NHERI Science Plan (https://doi.org/10.17603/ds2-4s85-mc54), the facility will enable new research discoveries that can help protect human life, reduce damage, minimize economic losses, and allow communities to recover more quickly after extreme coastal hazard events. The experimental capabilities will allow researchers to develop new technologies for adaptive engineering to mitigate the effects of coastal hazards. Experimental data generated from the use of this facility will be archived in the Data Depot on the NHERI web portal. The facility will conduct annual user workshops, host Research Experiences for Undergraduate students, and enable the development of K-12 instructional content developed via Research Experiences for Teachers.The Large Wave Flume and Directional Wave Basin are capable of generating long-period waves for tsunami research and short-crested waves for hurricane wave research and can be used for the study of hydraulic-structure-sediment phenomena, such as tsunami and hurricane inundation dynamics in constructed and natural environments; tsunami and hurricane wave forces on near-coast civil infrastructure; and tsunami and hurricane surge interaction with sediments causing erosion and localized scour. The wave flume is a two-dimensional representation of the coast (looking directly out to sea), eliminating the complexity of longshore currents and wave direction, and allowing a cross-section of test specimens to be studied at scales from approximately 1:50 up to 1:1 (prototype) scale to model wave-structure interaction of building subassemblies, native sediments for beaches and dunes, and live coastal vegetation. The wave basin increases the system complexity to three dimensions by extending laterally, enabling the study of coastal communities and complex harbors when wave direction is important. The wave basin generally requires a decrease in scale by a factor of five (1:250 to 1:5). In addition to these two resources, the facility will provide standard and state-of-the-art instrumentation to assess wave conditions, velocity, and response variables such as stress, strain, load, and sediment transport (scour and erosion).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.

自然灾害工程研究基础设施（NHERI）由美国国家科学基金会（NSF）支持，作为一个分布式，多用户的国家设施，为自然灾害工程研究社区提供研究基础设施，包括地震和风力工程实验设施，网络基础设施（CI），计算建模和仿真工具，高性能计算资源和研究数据。以及教育和社区外展活动。NHERI最初由NSF 14-605和NSF 15-598项目资助，自2015年以来，NHERI一直通过单独但协调的五年研究基础设施奖项为网络协调办公室，CI，计算建模和仿真中心以及实验设施，包括灾后快速反应研究设施。有关NHERI资源的信息可在NHERI门户网站（https：//www.example.com）上查阅。www.DesignSafe-ci.org为NHERI颁发的奖项有助于NSF在国家减少地震灾害计划（NEHRP）和国家减少风暴影响计划（NWIRP）中发挥作用。 NHERI实验设施将为NSF支持的研究和教育奖项提供实验资源，用户服务和数据管理基础设施。该奖项将于2021年1月1日至2025年9月30日更新俄勒冈州州立大学的NHERI实验设施。通过该奖项，俄勒冈州州立大学将继续维护，运营和增强大型波浪水槽和定向波盆地，以提供实验设备，仪器和技术支持，使研究能够减轻自然灾害的影响，如海岸浪涌和海浪和海啸，对国家的民用基础设施和社区。正如NHERI科学计划（https：//doi.org/10.17603/ds2-4s85-mc54）中所概述的那样，该设施将实现新的研究发现，有助于保护人类生命，减少损害，最大限度地减少经济损失，并使社区在极端沿海灾害事件后更快地恢复。实验能力将使研究人员能够开发适应性工程的新技术，以减轻沿海灾害的影响。使用该设施生成的实验数据将存档在NHERI门户网站的数据库中。该设施将举办年度用户研讨会，为本科生举办研究体验，并通过教师研究体验开发K-12教学内容。大型波浪水槽和定向波浪池能够产生用于海啸研究的长周期波浪和用于飓风波浪研究的短峰波浪，并可用于水力结构沉积现象的研究，例如，人工环境和自然环境中的海啸和飓风淹没动态;海啸和飓风波浪对近海岸民用基础设施的作用力;海啸和飓风涌浪与沉积物的相互作用，造成侵蚀和局部冲刷。波浪水槽是海岸的二维表示（直接看向大海），消除了沿岸水流和波浪方向的复杂性，并允许以约1：50至1：1（原型）比例研究测试样本的横截面，以模拟建筑物的波浪-结构相互作用，海滩和沙丘的天然沉积物，以及活的沿海植被。波浪盆地通过横向延伸将系统复杂性增加到三维，使得当波浪方向很重要时能够研究沿海社区和复杂港口。波浪水池通常需要将比例缩小五倍（1：250至1：5）。除了这两个资源，该设施将提供标准和最先进的仪器，以评估波浪条件，速度和响应变量，如应力，应变，负荷和沉积物输运（冲刷和侵蚀）。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。
