Graduate students will participate in the project. One Ph.D. candidate will use these data as part of his dissertation research into the utility of electrical resistivity tomography.
|In an effort to better understand and define the lateral and vertical extent of karstic voids that have developed immediately adjacent to a roadway in Nixa Missouri, MS&T will acquire electrical resistivity tomography data.
We will acquire geophysical data using a Supersting R8 resistivity unit. Resistivity probes will be placed on 5-foot centers. The subsurface will be imaged a depth of approximately 50-60 feet below ground surface.
|In an effort to better understand and define the lateral and vertical extent of active karst features in immediate proximity to paved municipal roadways in Nixa Missouri, MS&T will acquire electrical resistivity tomography (ERT) data. The intent is to use this non-invasive technology to map the lateral and vertical extent of the active karst features so that appropriate mitigation plans can be developed.
Relationship to other Research/Projects
Anderson routinely works with non-invasive imaging technologies in support of highway-related applications.

Technology Transfer Activities
|Results will be presented at national conference and published. The deliverables will include an evaluation of the utility of the electrical resistivity tomography method for mapping shallow water-filled voids and a discussion of the degree of resolution provided by the tool.
|Maps and geologic cross-sections depicting the lateral and vertical extent of soil, rock and airfilled voids in proximity to the active karst features.
If MS&T is successful, we will demonstrate that the electrical resistivity tomography tool can be used to reliably image karstic voids at depths on the order of less than 60 ft. The results of this research will be presented at major conferences and as peer-reviewed journals articles.
