Time domain reflectometry (TDR) is used to determine embankment slope movement and piezometric levels easily, safely and economically. The digital nature of the data allows remote monitoring by telemetry. A cable tester sunds a waveform down a coaxial cable ...

The author's research and experience suggest a number of additional geotechnical monitoring applications for TDR. For example, foam or air filled coaxial cables can be used to monitor groundwater levels. The presence of water in the dielectric produces a characteristic ...

This paper presents some general information about the exploration and classification of earth materials.
