Abstract

"The dissertation is made up of three papers, which discuss the utility of geophysical tools in earthfill dam investigations and dredged oyster bed characterization.

In the first paper, an earthfill dam in Warren County, Missouri was effectively investigated for seepage through the dam and its outlet works using an integration of the electrical resistivity tomography, induced polarization and spontaneous potential geophysical tools. Recommendations were subsequently made based on the results of the study on grout locations to prevent further seepage. In the second paper, a similar study of earthfill dam seepage was conducted on a different dam in Southern Missouri. The potential seepage zones through the dam were identified using the electrical resistivity tomography tool and available Lidar data for the site. It was observed that the mapped seepage pathway through the dam at the site were consistent with the orientation of geologic structures such as faults, joints and lineaments around the study area. It is expected that the results of the study would help in the planning, design, inspection and maintenance of earthfill dams in the United States.

In the third paper, marine electrical resistivity tomography tool was effectively uses to characterize dredged oyster deposit in Mobile Bay, Alabama. The results of the study were expected to be used in assessing the suitability of the dredge location and other similar locations in the bay as potential sites for the deposit of dredge materials presently removed from the Mobile Bay shipping channels"--Abstract, page iv.
