Geophysical Detection of Voids within the Levee, Duck Creek Conservation Area, Missouri

Ground penetrating radar (GPR) and resistivity data were acquired along the levee in the Duck Creek Conservation Area in southeast Missouri. The primary objective was to locate any/all shallow air-filled voids (rodent burrows) that might be present beneath the firm-packed roadway atop critical sections of the levee. A total of 160 ft of resistivity data and 19,200 ft of GPR data were acquired along test sections of roadway. These geophysical data were processed and interpreted on-site. Thirteen prominent anomalous features were identified on the geophysical data and tested using a shallow drill. Drilling confirmed that none of the anomalous features were caused by shallow, air-filled voids.
