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). ***

该奖项将资助堪萨斯州立大学土木工程系的Lakshmi Reddi博士与高丽大学土木工程系的in - mo Lee教授进行为期36个月的合作研究项目，研究土壤中颗粒输送对过滤器性能的影响。目前的合作将为Reddi博士的研究增加一个国际合作的维度。CMS - 9713708。这项研究解决了以下问题：许多土壤结构需要过滤器来防止侵蚀和管道，这些过滤器可能会损坏邻近的结构，如果这些过滤器堵塞，可能会造成损害。国内（CMS）项目涉及过滤器堵塞的物理化学和生物机制的基础研究。高丽大学的研究小组正在进行的一项补充研究侧重于残留土壤中的颗粒动员（以及与此动员相关的过滤器堵塞）和对失效过滤器的实地调查。合作研究工作的总体目标是将美国和韩国的国内研究联系起来，以便全面和完整地了解过滤器堵塞机制。具体目标是：(1)交换基层土壤颗粒迁移和过滤器颗粒夹持的实验数据；(2)共享实地调查数据；(3)结合韩国的实地调研，对美国国内研究项目中的滤波器设计标准进行归纳和验证。韩国的研究成果将有助于验证美国正在进行的理论和实验室研究，因此预计此次合作将带来互利。与此同时，两支团队都将受益于韩国团队收集的数据的理论处理。因此，合作将提供一个独特的机会来整合问题的两种不同观点，一种是基础实验室规模的研究，另一种是现场规模和实践研究。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。该项目将为美国研究生在一个重要的研究领域提供国际培训和经验。韩国的参与得到了韩国科学工程财团（KOSEF）的支持。＊＊＊
