US-Oman Cooperative Research: Modeling of Heterogeneous Aquifers

描述：该奖项是为了表彰由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David Loper博士和阿曼苏丹国马斯喀特Al-Khodh科学学院数学和统计系Ibrahim Eltayeb博士领导的一个阿曼团队的联合研究项目。研究小组的目的是开发在佛罗里达和阿曼等地发现的岩溶含水层中运移的概念、数学和实验室模型。在佛罗里达和阿曼，流体流动和容器运输主要受相关不均质性的存在，如岩溶管道和裂缝的存在。在佛罗里达州，管道占主导地位，而在阿曼，这两种类型的不均匀都存在。在这个项目中，它打算将弗洛里丹-导管模型扩展到包括裂缝。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，但在统计意义上可以改进风险估计。范围：非均质介质中流动和传输的研究领域是与来自农业和工业的有毒废物有关的具有社会影响的重要课题。地下水流的分析和预测问题对水资源和水质研究都具有重要意义。这种流动的良好数学模型对这些研究极其重要。佛罗里达州立大学和阿曼小组都有能力取得有用和重要的成果，对佛罗里达和阿曼来说，水资源和水质问题都相当重要。这项建议符合支持在互利领域开展国际科学合作的国际目标。该项目的资金由国际项目部和地球科学部提供。

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.
