9905081NielsenDescription: This award is to support a collaborative project by Drs. Kent Nielsen and Mohamed Abdelsalam, Department of Geosciences, University of Texas, Dallas, Texas and Dr. Hassan El-Etr, National Authority for Remote Sensing and Space Sciences, Cairo, Egypt. These scientists plan to use remote sensing and geological mapping, in combination with other relevant data from their GIS database (most notably seismicity) to study the Kalabsha fault in Upper Egypt. Specifically they plan to: 1. Prepare a 1:50,000 geologic and structural map of the Kalabsha fault, by integrating satellite imagery, earthquake distributions, and geologic field studies. 2. Outline the structural evolution of the Kalabsha fault using structural geology and tectonic geomorphological techniques. 3. Develop remote sensing and field criteria for studying similar faults in the area and for evaluating their potential reactivation. 4. Study the causes of the seismicity in the Kalabsha fault, with special attention to the possible relationship between the seismicity and the water loading resulting from the presence of the Aswan dam. Scope: The existence of a fault near the Aswan High Dam raises the important scientific question of the relationship of building large dams to increases in seismicity in its surrounding areas. This research may help identify previously unrecognized faults, and may improve understanding of the regional tectonic setting. This work would help in quantifying seismic hazard, an issue of paramount importance to Egypt, where knowledge of the activity on the faults in question is critical for future planning. The collaborating scientists have strong background in remote sensing processing and interpretation, and have the equipment necessary for working with the remote sensing imagery. The geologic and structural map to be produced of the Kalabsha fault will be a useful product for numerous investigators. The emphasis on new data, such as radar, and relatively new tectonic geomorphology techniques, makes this work a novel contribution for this particular area. The project will support a US graduate student who will have an opportunity to gain experience through this international collaboration. This proposal meets the INT objective of supporting collaborative research in areas of mutual interest. 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.

9905081 Nielsen描述：该奖项旨在支持德克萨斯州达拉斯德克萨斯大学地球科学系的肯特·尼尔森博士和穆罕默德·阿卜杜勒-阿齐兹博士以及埃及开罗国家遥感和空间科学局的哈桑·埃尔-埃特尔博士的一个合作项目。 这些科学家计划利用遥感和地质测绘，并结合其地理信息系统数据库中的其他相关数据（特别是地震活动），研究上埃及的Kalabsha断层。 具体而言，他们计划：1。通过整合卫星图像、地震分布和地质实地研究，绘制1：50，000的Kalabsha断层地质和结构图。2.运用构造地质学和构造地貌学技术，勾勒出喀拉卜沙断裂的构造演化。3.制定遥感和现场标准，以研究该地区的类似断层，并评估其潜在的再活化。4.研究Kalabsha断层地震活动的原因，特别注意地震活动与阿斯旺大坝造成的水负荷之间的可能关系。 适用范围：阿斯旺大坝附近断层的存在提出了一个重要的科学问题，即建造大坝与其周围地区地震活动增加的关系。 这项研究可能有助于识别以前未被识别的断层，并可能提高对区域构造背景的理解。 这项工作将有助于量化地震危险性，这对埃及来说是一个至关重要的问题，了解有关断层的活动对于未来的规划至关重要。 参与合作的科学家在遥感处理和判读方面有很强的背景，并拥有处理遥感图像所需的设备。 即将制作的卡拉布沙断层地质和结构图将是许多调查人员的有用产品。 新的数据，如雷达和相对较新的构造地貌技术的重点，使这项工作的一个新的贡献，这一特定领域。 该项目将支持一名美国研究生，他们将有机会通过这种国际合作获得经验。 该提案符合INT的目标，即支持在共同感兴趣的领域进行合作研究。 该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。
