Research has been in progress since July 1970 to determine which geophysical and remote-sensing methods offer the most promising results for detecting subsurface cavities and what might be done to further develop them. Through extensive field tests, it has been determined that none of the standard electrical resistivity procedures give consistently good results. As a result of the initial field testing, a new process of data interpretation has been developed for one specific electrode configuration. Cavities less than 10 feet in diameter and at the depths greater than 100 feet were located. Research is continuing to adapt this process for locating water- or mud-filled cavities.

Research has been in progress since July 1970 at the U.S. Army Engineer Waterways Experiment Station to determine these methods which offer the most promising results for detecting subsurface cavities and what might be done to further develop them. Through extensive field tests, it has been determined that none of the standard electrical resistivity procedures give consistently good results. However, as a result of the initial field testing, a new process of data interpretation has been developed for one specific electrode configuration. The modified procedure produced excellent results during field tests over known cavities in Indiana and Missouri. Cavities less than 10 ft in diameter and at depths greater than 100 ft were located. To date, this new procedure has been applied only to air-filled cavities. However, research is continuing to adapt this process for locating water- or mud-filled cavities.

The research is part of a program underway to evaluate remote sensing instrumentation and methods for locating subsurface cavities that can cause serious highway construction and maintenance problems. Three methods of subsurface cavity detection based on different geophysical techniques were experimentally evaluated, including ground-penetrating radar, gravity profiling, and earth resistivity profiling. Tests were conducted at three sites having different geological environments. Verification tests showed all methods to be capable of locating air-filled cavities.
