Standoff High-Frequency Electromagnetic Induction Response of Unsaturated Sands: A Tank-Scale Feasibility Study
Autor: Dan R. Glaser, Fridon Shubitidze, Benjamin E. Barrowes
Publikováno v: Journal of Environmental and Engineering Geophysics. 27:45-51
Standoff electromagnetic induction (EMI) measurements of complex conductivity and complex permittivity for engineering soil properties have the potential to revolutionize the way the US Army handles route planning and infrastructure assessment. An un

A Site-specific Comparison of Permeability Prediction Models in Alluvial Sediments from Physical and Geoelectrical Measurements
Autor: Dan R. Glaser
Publikováno v: Journal of Environmental and Engineering Geophysics. 26:315-322
An evaluation of five petrophysical models for hydraulic permeability predication was completed for a site-specific set of alluvial sediments. The models considered were the Kozeny-Carmen (1927–1937), Börner (1996), Revil-Cathles (1999), and two R

Localization of deep voids through geophysical signatures of secondary dewatering features
Autor: Philip Reppert, Dennis L. Brinkley, Dan R. Glaser, Katrina Burch
Publikováno v: GEOPHYSICS. 86:WA139-WA152
Discrete deep targets are a significant challenge for most surface-based geophysical techniques, even when considering high property contrasts. In general, surface-based geophysical methods lose lateral and vertical resolution with depth as a result

Improving detection of acoustic sources by coiling fiber optic cable
Autor: Bonnie J. Jones, Kyle G. Dunn, Mark L. Moran, Eric B. Dunn, Danielle Peterson, Sergey N. Vecherin, Dan Costley, Allan Wheeler, Dan R. Glaser, Aaron C. Meyer
Publikováno v: Detection and Sensing of Mines, Explosive Objects, and Obscured Targets XXV.
Distributed acoustic sensing (DAS) systems using fiber optic (FO) cables are becoming commonplace in many perimeter security applications. They have the advantage of cost-effectively covering large geographic expanses without temporal or spatial gaps
