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.

自然危害工程研究基础设施（NHERI）得到国家科学基金会（NSF）作为分布式的，多用户的国家设施，可为自然危害工程研究社区提供获得地震和风力工程实验设施的研究基础设施的访问，包括Cyber​​infrasture（CIBERTACTION（CI），计算上的模型和仿真工具，以及进行计算和高度计算机，以及高级计算和高级计算，包括网络和风能工程实验设施。 NHERI最初由计划招标资助NSF 14-605和NSF 15-598，自2015年以来从2015年以来通过单独但协调的五年研究基础设施奖励网络协调办公室，CI，计算建模和仿真中心以及实验性设施，包括后置措施，快速响应研究设施。有关NHERI资源的信息可在NHERI Web Portal（https://www.designsafe-ci.org）上获得。 NHERI颁发的奖项促进了NSF在国家地震危害计划（NEHRP）和国家风暴影响减少计划（NWIRP）中的作用。 NHERI实验设施将为NSF支持的研究和教育奖提供访问其实验资源，用户服务和数据管理基础架构。该奖项将于2021年1月1日至2025年9月30日在俄勒冈州立大学的NHERI实验设施续签。通过该奖项，俄勒冈州立大学将继续维护，运营和增强大波浪水流和方向波浪盆地，以提供对实验设备，仪器的访问，以促进诸如沿海地区和沿海地区的影响，并在沿海地区进行研究，并在沿海地区进行浪潮，并在沿海地区进行浪潮，并浪费了浪潮，并浪费了浪漫的浪潮，并浪费了浪潮，并浪费了浪漫的浪潮，并逐渐浪费了范围的浪潮。基础设施和社区。正如NHERI科学计划（https://doi.org/10.17603/ds2-4s85-mc54）所述，与自然危害工程中的宏伟研究挑战一致，该设施将启动新的研究发现，这些发现可以帮助可以帮助保护人类的生活，减少损害，使社区更快地恢复过沿海地区的危险事件，从而有助于帮助人类生命，并恢复过度危险。实验能力将使研究人员能够开发自适应工程的新技术，以减轻沿海危害的影响。使用此设施的使用产生的实验数据将在NHERI Web门户网站的数据库中存档。该设施将举办年度用户研讨会，针对本科生的主持研究经验，并能够开发通过教师的研究经验开发的K-12教学内容。大波浪水槽和方向性波浪盆地能够为海啸研究和短暂的研究用于飓风研究的潮流研究，能够为水力学的研究提供长期的潮流，从而可以使用水力学研究来进行水力研究。以及在近乎沿海基础设施上的海啸和飓风力量等沉积物；以及与沉积物的海啸和飓风激增相互作用，导致侵蚀和局部冲刷。 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 species 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.波盆地通过横向延伸，将系统的复杂性提高到三个维度，从而在波动方向很重要时可以研究沿海社区和复杂的港口。波盆通常需要减少尺度五（1：250至1：5）。除这两种资源外，该设施还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，例如压力，应变，负载和沉积物运输（SCOUR和侵蚀）。该奖项反映了NSF的法定任务，并通过使用基金会的知识优点和广泛影响来评估来表现出值得通过评估的支持。
