US-Egypt Cooperative Research: Investigation of Groundwater Flow Heterogeneity in Fractured Aquifers Using Stochastic Modeling, A Case Study of Fractured Limestone in Sinai

项目资助美国俄克拉何马大学石油与地质工程系张东晓博士与埃及开罗国家水研究中心Mahmoud Bakr博士的合作研究。他们计划利用随机建模技术，以西奈地区裂缝性石灰岩为例，研究裂缝性含水层中地下水流动的非均质性。智力优势：工作的主要重点是研究如何通过综合实地考察和建模程序改进我们对裂缝性石灰岩的概念化。利用裂缝分析、泵送和示踪技术以及地球物理学对流动特性进行详细研究，将用于开发裂缝石灰岩中地下水流动的修订模型。实地工作将分阶段进行，从而使建模程序能够直接与实地实验进行交互，并为实地实验的规划和解释提供指导。因此，整个程序开发将以迭代的方式进行。更广泛的影响：该项目将支持两国的研究生和初级科学家。新的实验将在埃及NWRC管理的现场进行，新的实验地点很可能会加强研究和教育的基础设施。这项研究结果将在评审期刊上发表。研究结果可用于埃及干旱环境下的水资源管理。两支团队将通过合作共同积累经验，其中美国团队将利用埃及团队获得的现场数据，而后者将使用前者的数值和理论专业知识。两名美国研究生将参与该研究项目。该项目得到了美国-埃及联合基金项目的支持，该项目向两国的科学家和工程师提供赠款，以开展这些合作活动。

0511496ZhangDescription: This project supports a collaborative research between Dr. Dongxiao Zhang, Department of Petroleum and Geological Engineering, University of Oklahoma, Norman and Dr. Mahmoud Bakr, National Water Research Center, Cairo, Egypt. They plan to investigate groundwater flow heterogeneity in fractured aquifers using stochastic modeling techniques with a case study of fractured limestone in Sinai.Intellectual Merits: The main focus of the work is to investigate how our conceptualization of the fractured limestone can be improved through an integrated fieldwork and modeling program. Detailed studies of flow properties using fracture analyses, pumping and tracer techniques and geophysics will be used to develop a revised model of groundwater flow in fractured limestone. The fieldwork will be taken in phased manner, thereby allowing the modeling program to directly interact with and provide direction on the planning and interpretation of the field experiments. Thus, the whole program development will be undertaken in an iterative manner.Broader Impacts: The project will support graduate students and junior scientists in both countries. New experiments will be developed in the field site run by Egypt NWRC and it is very likely that the new experiment sites will enhance infrastructure for research and education. The research will result in publications in refereed journals. The results can be used for water resource management in the arid environment of Egypt. The two teams will build up their experience jointly through the collaboration, where the US team will utilize the field data obtained by Egyptian team, while the latter will use the numerical and theoretical expertise of the former. Two US graduate students will participate in the research project. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
