PIRE: Modeling of Flood Hazards and Geomorphic Impacts of Levee Breach and Dam Failure

0730246AbstractChaudhry 该奖项为提交给 2007 年 OISE 国际研究和教育合作伙伴 (PIRE) 竞赛的提案提供支持。 该项目涉及美国方面的合作，包括南卡罗来纳大学哥伦比亚分校、波多黎各大学、南卡罗来纳州立大学、比利时鲁汶天主教大学和葡萄牙里斯本高等技术学院。 合作伙伴建议以统一的方式对沉积物的侵蚀、沉积和运输进行研究，包括堤坝或大坝溃决后河床的移动，以提供有关由此产生的洪水灾害和相关地貌影响的完整而准确的图片。 将开发一个三维模型来研究高度瞬变流产生的地貌过程。 该模型通过耦合流动和床流动、求解非静水压力场以及包括沉积物粘聚力的影响，将摆脱现有数值模型的许多限制。 实验室研究将有助于理解和量化洪水波造成的土壤侵蚀和河床移动和流动的机制，并为计算机模型的验证提供测试数据。 选择这两个欧洲合作伙伴是因为他们独特的实验室设施、技术专长、高级人员的经验以及正在进行的有关该主题的资助研究。 不同的实验将利用每个欧洲实验室的独特设施。 欧洲合作伙伴还可以参与欧盟委员会 (EC) 支持的更大的欧洲级项目，从而获得额外的好处。 更广泛的影响。 教育计划包括教师、研究生和本科生的交流、水资源课程的国际化、实地考察以及研究生课程的开发。 每年有10名本科生和5名研究生、一名研究教授、一名博士后以及多名美国和欧洲研究人员参与该项目活动。 高中生和本科生将获得暑期研究机会，女性和代表性不足的群体将占该项目参与者的三分之一。 拟议研究的结果将有助于规划大坝或堤坝溃决后的紧急情况以及制定减轻不利生态和形态影响的策略。

0730246AbstractChaudhryThis award provides support for a proposal submitted to the 2007 OISE Partnerships for International Research and Education (PIRE) competition. It involves a collaboration on the US side between the University of South Carolina at Columbia, the University of Puerto Rico, and South Carolina State University with the Catholic University of Louvain in Belgium and the Instituto Superior Tecnico in Lisbon, Portugal.Intellectual Merit. The collaborative partners propose to conduct research on erosion, deposition, and transport of sediment including the mobilization of the bed following levee or dam failure in a unified manner to provide a complete and accurate picture of resulting flood hazard and the associated geomorphic impacts. A three-dimensional model will be developed to study the geomorphic process produced by highly transient flow. The model will be free of many limitations of existing numerical models by coupling the flow and bed mobilization, solving the non-hydrostatic pressure field, and including the effects of sediment cohesion. The laboratory studies will help to understand and quantify the mechanism of soil erosion and bed movement and mobilization by the flood wave and provide test data for the verification of computer models. The two European partners were selected because of their unique laboratory facilities, technical expertise, experience of senior personnel, and ongoing funded research on the topic. Different experiments will make use of the unique facilities at each of the European labs. The European partners offer the added benefit of being part of a larger European-level project supported by the European Commission (EC). Broader Impacts. The educational plan includes the exchange of faculty members, graduate and undergraduate students, internationalization of water resources curricula, field visits, and development of postgraduate courses. Each year, 10 undergraduate and 5 graduate students, a research professor, a post-doctoral fellow, and several US and European researchers will participate in the project activities. High school and undergraduate students will be offered summer research opportunities, and female and underrepresented groups will comprise one-third of the project's participants. The results of the proposed research will be useful in planning for emergencies following dam or levee failure and the development of strategies for the mitigation of adverse ecological and morphological impacts.
