Modeling GPR data to interpret porosity and DNAPL saturations for calibration of a 3-D multiphase flow simulation
Dense nonaqueous phase liquids (DNAPLs) are a pervasive and persistent category of groundwater contamination. In an effort to better understand their unique subsurface behavior, a controlled and carefully monitored injection of PCE (perchloroethylene), a typical DNAPL, was performed in conjunction with the University of Waterloo at Canadian Forces Base Borden in 1991. Of the various geophysical me

GPR data processing computer software for the PC
The computer software described in this report is designed for processing ground penetrating radar (GPR) data on Intel-compatible personal computers running the MS-DOS operating system or MS Windows 3.x/95/98/ME/2000. The earliest versions of these programs were written starting in 1990. At that time, commercially available GPR software did not meet the processing and display requirements of the U

Magnetic and GPR surveys of a former munitions foundry site at the Denver Federal Center
We made magnetometer and ground penetrating radar (GPR) surveys over part of the foundation of a World War II-era foundry located on the Denver Federal Center. The site contains a number of highly magnetic source bodies, concrete foundation walls, and underground openings, buried under a clay cap. The cap is several feet thick and has a conductivity of about 35 mS/m, making the features underneath

Landfill mapping using multi-disciplinary geophysical techniques at the U.S. Air Force Academy, Colorado Springs, CO
This paper describes a multi-disciplinary geophysical survey conducted over a
landfill on the U.S. Air Force Academy grounds near Colorado Springs, Colorado.
The landfill is known to contain waste generated during the construction of the
Academy and reportedly contains buried steel drums. The purpose of the
geophysical surveys was to determine the subsurface distribution of buried
metallic objects
