US-Oman Cooperative Research: Modeling of Heterogeneous Aquifers

Loper描述：该奖项是为了支持佛罗里达州塔拉哈西佛罗里达州立大学地球物理流体动力学研究所所长大卫Loper博士和阿曼苏丹国麝香Al-Khodh苏丹卡布斯大学科学学院数学与统计系Ibrahim Eltayeb博士领导的阿曼团队的联合研究项目。 研究小组的目的是开发概念，数学和实验室模型的运输岩溶含水层，如发现在佛罗里达和阿曼。 在佛罗里达和阿曼，流体流动和安全壳运输主要是由相关的不均匀性，如岩溶管道和裂缝的存在。 在佛罗里达管道占主导地位，而在阿曼两种类型的不均匀性。 在这个项目中，它的目的是扩展佛罗里达管道模型，包括骨折。 虽然不能确切地知道地下非均质性的精确结构，因此准确或真实的“预测”是不切实际的，但可以在统计意义上改进风险估计。适用范围：非均质介质中的流动和输运研究是一个重要的课题，其社会影响与来自农业和工业的有毒废物有关。 地下水流的分析和预测问题是水资源和水质研究的重要内容。 这种流动的良好数学模型对这些研究极为重要。 佛罗里达州立大学和阿曼小组都能够获得有用和重要的结果，对佛罗里达和阿曼来说，水资源和水质问题相当重要。 这一建议符合INT在互利领域支持国际科学合作的目标。 该项目的资金由国际方案司和地球科学司提供。

LoperDescription: This award is for support of a joint research project by Dr. David Loper, Director, Geophysical Fluid Dynamics Institute, Florida State University, Tallahassee, Florida and an Omani team led by Dr. Ibrahim Eltayeb, Department of Mathematics and Statistics, College of Science, Sultan Qaboos University, Al-Khodh, Muscat, Sultanate of Oman. The purpose of the research teams is to develop conceptual, mathematical, and laboratory models of transport in karstic aquifers such as found in Florida and Oman. In Florida and Oman fluid flow and containment transport is dominated by the presence of correlated inhomogenities such as karstic conduits and fractures. In Florida conduits predominate, while in Oman both types of inhomogeniety are present. In this project it is intended to extend the Floridan-conduit model to include fractures. While the precise structure of the heterogeneities in the subsurface cannot be known with certitude, and thus an accurate or true "prediction" is impractical, improvement can be made in risk estimates in a statistical sense. Scope: The research area of flow and transport in a heterogeneous medium is an important topic with societal impact related to toxic waste from agriculture and industry. The problem of analysis and prediction of groundwater flows is important to the study of both water resources and water quality. Good mathematical models of such flows are extremely important to those studies. Both the Florida State University and Omani groups are capable of obtaining useful and important results, and for both Florida and Oman, the issues of water resources and water quality are quite important. This proposal meets the INT objective of supporting internatinal scientific collaboration in areas of mutual benefit. Funding for this project is provided by the Division of International Programs and the Division of Earth Sciences.
