N2 - In recent years Time Domain Reflectometry (TDR) has been introduced as a new system for subsurface deformation monitoring in boreholes. AsTDR can easily be operated continuously using dataloggers it is an economic alternative to expensive inclinometer chains. To date TDR can identify and localize discrete deformation zones with high accuracy. AsTDR measurements are influenced by a great variety of parameters, as for instance the used coaxial cable and grout type, they often are ambiguous, thereby hindering the quantification of the deformation. By the definition of calibrated installation standards and the usage of signal analysis software, it is possible to overcome this and reliably quantify deformation using TDR. Since TDR data can be acquired continuously as well as remotely, it is possible to integrate a TDR measuring system into a geo-sensor network.
