Detection and mapping of fractures and cavities using borehole radar Detection and mapping of fractures and cavities using borehole radar
Borehole radar can be used in a single-hole reflection mode or in a cross-hole tomography mode. In the reflection mode, radar provides an image of discontinuities in the bedrock surrounding a borehole, including bedding planes, lithologic contacts, fractures, and cavities. The measurements are either directional or omni-directional, depending upon the type of equipment and antennas. In...

An integrated surface-geophysical investigation of the University of Connecticut landfill, Storrs, Connecticut: 2000 An integrated surface-geophysical investigation of the University of Connecticut landfill, Storrs, Connecticut: 2000
A surface-geophysical investigation to characterize the hydrogeology and contaminant distribution of the former landfill area at the University of Connecticut in Storrs, Connecticut, was conducted in 2000 to supplement the preliminary hydrogeologic assessment of the contamination of soil, surface water, and ground water at the site. A geophysical-toolbox approach was used to characterize...

Borehole-geophysical investigation of the University of Connecticut landfill, Storrs, Connecticut Borehole-geophysical investigation of the University of Connecticut landfill, Storrs, Connecticut
A borehole-geophysical investigation was conducted to help characterize the hydrogeology of the fractured-rock aquifer and the distribution of unconsolidated glacial deposits near the former landfill and chemical waste-disposal pits at the University of Connecticut in Storrs, Connecticut. Eight bedrock boreholes near the landfill and three abandoned domestic wells located nearby were...

Borehole-wall imaging with acoustic and optical televiewers for fractured-bedrock aquifer investigations Borehole-wall imaging with acoustic and optical televiewers for fractured-bedrock aquifer investigations
Imaging with acoustic and optical televiewers results in continuous and oriented 360 degree views of the borehole wall from which the character and orientation of lithologic and structural features can be defined for fractured-bedrock aquifer investigations. Fractures are more clearly defined under a wider range of conditions on acoustic images than on optical images including dark...
