Abstract
This presentation summarizes the Symposium and Workshop on Time Domain Reflectometry (TDR) in Environmental, Infrastructure, and Mining Applications, held at Northwestern University in Evanston, Illinois on September 8-9, 1994, was sponsored by the U.S. Bureau of Mines, Infrastructure Technology Institute at Northwestern University, and Los Alamos National Laboratory. The session on Instrumentation and Basic Physics focused on basic hardware and mechanics of both electrical and optical TDR. Soil Moisture-General concentrated on the application of TDR to measure volumetric water content in porous materia1s, especially soils. Soil Moisture and Contaminant Transport described the evolving application of TDR to measurement of solutes within pore fluids. Ground Water gathered applications of TDR to measurement of changes in fluid levels and pressures. Soil Moisture and Infrastructure describes applications of TDR to monitor changes in unfrozen and frozen subgrade moisture conditions. Finally, Rock and Soil Deformation presented applications of TDR to monitor displacements induced by mining and construction. Case history summaries of studies conducted by the USBM and U.S. Geological Survey will also be summarized.
