Time Domain Reflectometry (TDR) is a proven technology for monitoring slope stability by detecting ground movement along potential slip surfaces. A coaxial cable is installed in a borehole and grouted in place; when the slope deforms, the cable bends or shears, causing measurable reflections in the TDR signal. By analyzing these reflections, engineers can identify the depth and progression (but not magnitude or rate of movement) of slope movement in real time. TDR systems, consisting of a TDR cable and the GeoNet 8910-TDR Data Logger, provide a cost-effective, durable, and automated means of detecting slope instability. TDR systems are often used in combination with inclinometers and piezometers to provide a comprehensive assessment of slope performance and early warning of failure.
