U.S.-Korea Cooperative Research: Impact of Particle Transport in Soils on Filter Performance

9734804 Reddi该奖项提供资金，允许堪萨斯州立大学土木工程系Lakshmi Reddi博士与韩国大学土木工程系教授Lee In-mo一起进行为期36个月的合作研究项目，研究土壤中颗粒迁移对过滤器性能的影响。本次合作将为雷迪博士目前由美国国家科学基金会资助的研究增加一个国际合作层面。CMS-9713708。这项研究解决了这样一个事实，即许多土壤结构需要过滤器来防止侵蚀和可能损坏邻近结构的管道，以及如果这些过滤器堵塞可能会造成损坏的事实。国内(CMS)项目涉及滤池堵塞的物理化学和生物机理的基础研究。韩国大学的研究小组正在进行一项补充研究，重点是残留土壤中的颗粒动员(以及与这种动员相关的过滤器堵塞)和对失效过滤器的实地调查。合作研究的广泛目标是将美国和韩国的国内研究联系起来，以实现对过滤器堵塞机理的全面和完整的了解。具体目标是：(1)交换基础土壤中颗粒迁移和颗粒在过滤器中的捕获的实验数据；(2)共享现场调查数据；(3)根据韩国的实地调查，推广和验证美国国内研究项目中的过滤器设计标准。预计合作将互惠互利，因为韩国的研究结果将有助于验证美国正在进行的理论和实验室调查。同时，两队都将从韩国队收集的数据的理论处理中受益。因此，合作将提供一个独特的机会，将这一问题的两种不同角度结合起来，一种是基础实验室规模的研究，另一种是实地规模的实践研究。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。该项目将在一个重要的研究领域为美国研究生提供国际培训和经验。韩国的参与得到了韩国科学与工程基金会(KOSEF)的支持。***

9734804 Reddi This award provides funds to permit Dr. Lakshmi Reddi, Department of Civil Engineering, Kansas State University, to pursue with Professor In-Mo Lee, Department of Civil Engineering, Korea University, for 36 months, a program of cooperative research on the impact of particle transport in soils on filter performance. The present collaboration will add an international cooperative dimension to Dr. Reddi's research presently funded under NSF Grant No. CMS- 9713708. This research addresses problems arising from the fact that a number of soil structures need filters for protection against erosion and piping which can damage adjacent structures, and the fact that damage may result if these filters become clogged. The domestic (CMS) project involves fundamental studies on physicochemical and biological mechanisms of filter clogging. A complementary study being undertaken by the team at Korea University focuses on particle mobilization in residual soils (and filter clogging associated with this mobilization) and field investigations on failed filters. The broad objective of the cooperative research effort is to link up the U.S. and Korean domestic studies in order to achieve a comprehensive and complete understanding of the filter clogging mechanisms. Specific objectives are: (1) to exchange the experimental data on particle mobilization from base soils and particle entrapment in filters; (2) to share the data on field investigations; and (3) to generalize and validate the filter design criteria in the US domestic research project in light of field investigations made in Korea. Mutual benefit from the collaboration is expected because results from the Korean research will aid in validation of the theoretical and laboratory investigations being undertaken in the United States. At the same time, both teams will benefit from the theoretical treatment of data collected by the Korean team. Thus, the collaboration will provide a unique opportunity t o integrate two different perspectives of the problem, one, a fundamental laboratory scale study, and the other, a field-scale and practical study. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. This project will provide international training and experience for a U.S. graduate student in an important area of research. Korean participation is supported by the Korea Science and Engineering Foundation (KOSEF). ***
