Proposal Number: CBET-0742806Principal Investigator: Pancake, CherriAffiliation: Oregon State UniversityProposal Title: A Virtual Organization to Develop Complex, Multi-scale Models Addressing the Impact of Inundation on Natural and Man-made EnvironmentsOver 70% of the earth's surface is covered in water. When subject to extreme events, these water sources can become destructive floods, storm waves and surges, and tsunamis, resulting in billions of dollars of damage each year. However, mitigation measures are limited by the current incomplete understanding of such inundation phenomena and the impact they can have on landforms, structures, lifelines, and other objects in their paths. The underlying scientific and engineering issues are complex and involve scales from ranging from thousands of kilometers to micro-scale turbulence. There is no comprehensive model available that addresses even a single type of extreme inundation event. Developing a model that accurately portrays the complex, multi-scale behavior of an extreme inundation event and its effects on the surrounding environments requires collaboration among researchers in a broad spectrum of disciplines, including hydrodynamics, sedimentology, geomorphology, materials, and structural mechanics. This award provides funds for planning a Virtual Institute for Multi-scale Inundation Studies (VIMIS), a proposed engineering virtual organization to promote and facilitate the collaborative development of complex, multi-scale models for the impact of inundation on natural and man-made environments. Planning efforts include defining a draft organizational structure, membership features, and governance using user-centered techniques to arrive at community consensus on these issues. User-centered design methods will ensure that user requirements are identified accurately and comprehensively to create a conceptual plan for the VIMIS cyberinfrastructure (CI) and a prototype of that CI. The CI prototype will include initial versions of five portals: a shared membership portal supporting organizational membership and governance; a shared computation portal hosting numerical models for general research use; a shared data portal providing mechanisms for sharing a broad range of information within the broader community; a shared research portal supporting individual collaborative research projects and facilitating the process of sharing research products with the broader community; and a shared education portal disseminating the results of research efforts to educators and practitioners. The prototype will leverage other CI efforts from commercial, academic, and national laboratory communities. Expected outcomes of this award include: a cohesive community, user requirements for CI, a long-term conceptual design for that CI, and a prototype that demonstrates the value of CI to VIMIS. VIMIS, through its CI, will provide an environment that helps researchers identify mutual interests, find appropriate collaborators, and deal with the mechanics of collaborating with people from remote institutions. VIMIS will enable numerical efforts to model inundation beyond a single research group's computational capabilities to provide access to more advanced computing resources and enable integrative collaboration from computer graphics and fluid mechanics experts. An integral part of VIMIS is to develop shared teaching materials about the impact of inundation on natural and man-made environments, including shared models and tools, replay of experiments and other use of research data in the classroom, and integrative/cross-disciplinary materials all based on research findings. These efforts will also yield tools for hazard prevention and mitigation, thereby helping to save lives and minimize property losses.

提案编号：CBET-0742806主要研究者：Pancake，Cherry单位： 俄勒冈州州立大学提案标题：一个虚拟组织，以开发复杂的，多尺度模型，解决洪水对自然和人为环境的影响超过70%的地球表面被水覆盖。当受到极端事件的影响时，这些水源可能成为破坏性的洪水、风暴潮和海啸，每年造成数十亿美元的损失。 然而，由于目前对这种淹没现象及其可能对地形、结构、生命线和其路径上的其他物体产生的影响的不完全了解，缓解措施受到限制。潜在的科学和工程问题是复杂的，涉及从数千公里到微尺度湍流的尺度。 目前还没有一个全面的模型来处理甚至一种类型的极端洪水事件。 开发一个模型，准确地描绘了复杂的，多尺度的极端洪水事件的行为及其对周围环境的影响，需要在广泛的学科，包括流体力学，沉积学，地貌学，材料和结构力学的研究人员之间的合作。 该奖项为规划多尺度洪水研究虚拟研究所（VIMIS）提供资金，该虚拟研究所是一个拟议的工程虚拟组织，旨在促进和促进复杂的多尺度模型的协作开发，以了解洪水对自然和人为环境的影响。 规划工作包括定义组织结构草案、成员特征和治理，使用以用户为中心的技术来达成社区对这些问题的共识。 以用户为中心的设计方法将确保准确和全面地确定用户需求，以创建VIMIS网络基础设施的概念计划和该网络基础设施的原型。 CI原型将包括五个门户的初始版本：支持组织会员和治理的共享会员门户;托管一般研究使用的数值模型的共享计算门户;共享数据门户，提供在更广泛的社区内共享广泛信息的机制;一个共享的研究门户网站，支持个人合作研究项目，并促进与更广泛的社区共享研究产品的过程;以及一个向教育工作者和从业人员传播研究成果的共享教育门户网站。 该原型将利用来自商业、学术和国家实验室社区的其他CI工作。 该奖项的预期成果包括：一个有凝聚力的社区，用户对CI的需求，CI的长期概念设计，以及展示CI对VIMIS价值的原型。 通过其CI，VIMIS将提供一个环境，帮助研究人员确定共同利益，找到合适的合作者，并处理与远程机构人员合作的机制。VIMIS将使数字工作能够超越单个研究小组的计算能力来模拟洪水，以提供对更先进的计算资源的访问，并使计算机图形和流体力学专家能够进行综合合作。VIMIS的一个组成部分是开发关于洪水对自然和人为环境影响的共享教材，包括共享模型和工具、实验回放和在课堂上对研究数据的其他使用，以及所有基于研究结果的综合/跨学科材料。这些努力还将产生预防和减轻灾害的工具，从而有助于拯救生命和尽量减少财产损失。
