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.

ARRA声明：该职业提案将使用2009年《美国恢复与再投资法》（公法111-5）提供的资金颁发，并满足白宫备忘录的第2节中确定的要求，确保了2009年3月20日的负责支出的恢复法案，以确保2009年3月20日。该职业计划集成了研究和教育活动，以减少桥梁冲刷的风险，这是桥梁故障的第一大原因。 研究活动将创新传感器的开发与高级模拟相结合，并旨在克服现有理论和测试方法的局限性。 预计该研究计划将在1）创新实验室和现场传感器的开发方面做出重大科学贡献，以监视桥梁冲刷并了解涉及的动态破坏机制，特别是湍流对沉积物传输过程的影响以及2）能够准确预测在湍流条件下准确预测桥梁的桥梁冲刷的能力，以结合多尺度的计算动力学（CFD）和分析。 智力优点：传感器和网络计算工具将改善冲刷对策的设计，从而通过保护关键运输基础设施来确保安全和经济。职业研究计划将通过与政府机构和专业组织建立牢固的合作伙伴关系来实施。Broader的影响：这项综合的研究和教育职业发展计划还包括丰富本科，研究生和K-12学生和K-12学生和老师的工程课堂经验的活动。 这些将包括开发与基础设施工程有关的新课程材料，这是Case Western University在土木工程计划的重点领域。学生和K-12老师将获得基于研究的学习经验。 还将鼓励各个级别的学生参加实际或模拟的工程案例研究，以向地方及其他地区展示给社区。
