0730246 AbstractChaudhry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。 在美国方面，南卡罗来纳州哥伦比亚大学、波多黎各大学、南卡罗来纳州州立大学与比利时鲁汶天主教大学和葡萄牙里斯本的上级技术学院开展合作。 合作伙伴建议以统一的方式对侵蚀、沉积和沉积物的运输进行研究，包括堤坝或大坝倒塌后河床的移动，以提供所造成的洪水灾害和相关地貌影响的完整和准确的图片。 将建立一个三维模型来研究高度瞬变流产生的地貌过程。 该模型通过耦合水流和床面运动，求解非静水压力场，并考虑泥沙粘聚力的影响，克服了现有数值模型的许多局限性。 实验室研究将有助于了解和量化洪水波引起的土壤侵蚀和河床移动和动员的机制，并为计算机模型的验证提供测试数据。 之所以选择这两个欧洲合作伙伴，是因为它们拥有独特的实验室设施、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。 欧洲合作伙伴提供了额外的好处，成为欧洲委员会（EC）支持的更大的欧洲一级项目的一部分。 更广泛的影响。 教育计划包括教员、研究生和本科生的交流、水资源课程的国际化、实地考察和研究生课程的开发。 每年，10名本科生和5名研究生，一名研究教授，一名博士后研究员，以及一些美国和欧洲的研究人员将参加项目活动。 高中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。 拟议的研究结果将是有用的紧急情况下，大坝或堤坝故障的规划和发展战略，以减轻不利的生态和形态的影响。

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.
