Conference: Mid-scale RI-EW: Concepts for a Full-Scale Wave Flume for Coastal Resilience and Adaptation; Newark, Delaware; 16 May 2023

近40%的美国人口居住在沿海地区，沿海地区是主要的经济驱动力，包含陆上货物的运输路线，并且由于极端的风浪，各种关键基础设施处于危险之中。由于气候变化、海平面上升、异常天气模式和极端沿海风暴，这些地区的建筑和自然环境将遭受越来越多的洪水灾害。2022年飓风“伊恩”在佛罗里达州造成的后果表明，海浪和水位上升具有破坏性。然而，在美国还没有一个实验设施可以全面模拟波浪驱动的整体过程，以促进沿海地区的气候适应能力。该奖项将支持一个研讨会，以确定1)整体沿海过程研究和实验设施中的关键差距；2)一个以学术为基础的、全国性的、全面的波浪设施所需要的特征；3)支持波浪设施所需的计算能力。本次研讨会有助于国家科学基金会在国家减少风暴影响计划中的作用。讲习班将于2023年5月16日在特拉华州纽瓦克的特拉华大学举行。研讨会将确定对自然环境和建筑环境至关重要的沿海过程的关键研究空白，以促进气候适应能力，包括但不限于波浪-流相互作用、对基础设施的冲击力、冲刷和沉积物运输、破坏和破坏、岩土工程特征和基础稳定性。然后，研讨会将探讨全尺寸波浪设施所需的设计特征和能力以及相应的支持计算工作。讲习班将包括来自美国和国外的代表学术界、政府、非政府组织、私营部门和波浪实验室的与会者。讲习班报告将概述需要一个全尺寸波浪设施进行调查的关键研究问题以及这种设施的设计特点。该报告将在美国国家科学基金会支持的自然灾害工程研究基础设施设计安全数据库（https://www.DesignSafe-ci.org）.This)上公开发布，该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Nearly 40 percent of the United States population lives along coastlines, where coastal regions are major economic drivers, contain transport routes for overland cargo, and have a wide variety of critical infrastructure at-risk due to extreme wind and waves. These locations will suffer increased flooding hazards to the built and natural environments, via climate change, through sea level rise, abnormal weather patterns, and extreme coastal storms. The recent aftermath of Hurricane Ian in Florida in 2022 has demonstrated the destructive potential of increased waves and water levels. Yet, there is no experimental facility in the United States that can simulate holistic wave-driven processes at full scale to foster coastal climate resilience. This award will support a workshop to identify 1) the critical gaps in holistic coastal processes research and experimental facilities; 2) the needed characteristics of an academic-based, national, full-scale wave facility; and 3) the needed computational capabilities to support the wave facility. This workshop contributes to the National Science Foundation role in the National Windstorm Impact Reduction Program. The workshop will be held on 16 May 2023, at the University of Delaware in Newark, Delaware. The workshop will identify critical research gaps in coastal processes of importance to the natural and built environment to foster climate resilience, including, but not limited to, wave-current interaction, impact forces on infrastructure, scour and sediment transport, damage and failure, geotechnical characteristics, and foundation stability. The workshop will then explore the design characteristics and capabilities needed for a full-scale wave facility and the corresponding supporting computational efforts. The workshop will include participants from the United States and abroad, representing academia, government, non-governmental organizations, the private sector, and wave laboratories. A workshop report will outline the critical research questions requiring a full-scale wave facility for inquiry and the design characteristics of such a facility. The report will be publicly available on the NSF-supported Natural Hazards Engineering Research Infrastructure DesignSafe Data Depot (https://www.DesignSafe-ci.org).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.
