CAREER: Fusion of Multi-scale Sensing and Simulations for Bridge Scour Risk Management: An Integrated Research and Educational Plan

ARRA声明：本职业计划将使用2009年美国复苏和再投资法案（公法111-5）提供的资金进行奖励，并符合2009年3月20日白宫备忘录第2节规定的要求，该备忘录题为“确保复苏法案资金的负责任支出”。我还确认，作为认知项目官员，该提案不支持《恢复法》A部分第1604节所述的项目。这个职业计划整合了研究和教育活动，以减少桥梁冲刷的风险，这是桥梁故障的头号原因。 研究活动将创新传感器的开发与先进的模拟相结合，旨在克服现有理论和测试方法的局限性。 该研究计划预计将在以下方面做出重大科学贡献：1）创新的实验室和现场传感器，以监测桥梁冲刷并了解所涉及的动态破坏机制，特别是湍流对沉积物运输过程的影响; 2）结合多尺度计算流体动力学（CFD）方法和分析，准确预测湍流条件下桥梁冲刷的能力。 智力优势：传感器和网络计算工具将改善冲刷对策的设计，从而通过保护关键的运输基础设施来确保安全和经济。CAREER研究计划将通过与政府机构和专业组织的强有力的合作伙伴关系来实施。更广泛的影响：这个综合研究和教育职业发展计划还包括丰富本科生，研究生和K-12学生和教师的工程课堂经验的活动。 这些将包括与基础设施工程相关的新课程材料的开发，这是凯斯西方大学土木工程项目的重点领域。学生和K-12教师将获得基于研究的学习经验。 还将鼓励各级学生参加真实的或模拟的工程案例研究，向当地和其他地方的社区展示。

ARRA statement: This CAREER proposal will be awarded using funds made available by the American Recovery and Reinvestment Act of 2009 (Public Law 111-5), and meets the requirements established in Section 2 of the White House Memorandum entitled, Ensuring Responsible Spending of Recovery Act Funds, dated March 20, 2009. I also affirm, as the cognizant Program Officer, that the proposal does not support projects described in Section 1604 of Division A of the Recovery Act. This CAREER plan integrates research and educational activities to reduce the risk of bridge scour, the number one cause of bridge failures. The research activities combine the development of innovative sensors with advanced simulations, and aim to overcome the limitations of the existing theories and testing methods. The research program is expected to make significant scientific contributions in development of 1) innovative laboratory and field sensors to monitor bridge scour and understand the dynamic damaging mechanisms involved, specially the effects of turbulence on processes of sediment transport and 2) a capability to accurately predict bridge scour under turbulent conditions incorporating multi-scale Computational Fluid Dynamics (CFD) methods and analysis. Intellectual Merit: The sensors and cyber computational tools will improve the design of scour countermeasures thus ensuring safety and economy through protection of critical transportation infrastructures. The CAREER research plan will be implemented through a strong partnership with governmental agencies and professional organizations.Broader Impacts: This integrated research and educational career development program also includes activities that would enrich the engineering classroom experience of undergraduate, graduate, and K-12 students and teachers. These will include the development of new course materials related to infrastructure engineering, an area of focus of Civil Engineering program at Case Western University. Students and K-12 teachers will be provided with research-based learning experience. Students at all levels will also be encouraged to participate in real or simulated engineering case studies to be showcased to the communities on the local level and beyond.
