Acquisition of Electrical and Electromagnetic Instrumentation for Hydrogeophysical Research

0549325沃尔夫这笔赠款支持奥本大学地质和地理系购买一个多电极（48）电阻率成像系统。新设备将用于近地表沉积物的水文地球物理研究、地震引起的液化危害研究以及与受污染地下水有关的生物补救研究。这一增加的能力将促进开发现实的模型，用于研究控制沉积层中超压的瞬态性质的地质因素、土壤液化与场地地质的关系，以及某些地球物理方法在监测受污染地下水的生物修复方面的潜在用途。新设备和相关软件将允许教师和学生通过采用更现代的技术，如电阻层析成像（ERT），扩展对所获得数据的分析。它将取代现有的应用地球物理学和高级地球物理方法课程中使用的四电极系统，这些课程强调环境和工程应用。这些课程为本科生和研究生地质学专业，以及从土木工程，物理和数学的学生。

0549325WolfThis grant supports acquisition of a multi-electrode (48) resistivity imaging system by the Department of Geology and Geography at Auburn University. The new equipment will be used in hydrogeophysical studies of near-surface sediments, hazards studies of earthquake-induced liquefaction, and bioremediation studies relating to contaminated groundwater. This added ability will promote the development of realistic models for studying the geologic factors controlling the transient nature of overpressures in sedimentary layers, the relation of soil liquefaction to site geology, and the potential use of certain geophysical methods in monitoring the bioremediation of contaminated groundwater. The new equipment and associated software will allow faculty and students to expand upon analyses of acquired data by incorporating more modern techniques, such as electrical resistance tomography (ERT). It will replace a current 4-electrode system utilized in existing applied geophysics and advanced geophysical methods courses, which emphasize environmental and engineering applications. These courses serve undergraduate and graduate geology majors, as well as students from civil engineering, physics and mathematics.***
