Slope movements have caused severe damages of civil infrastructures and numerous human disasters. An early warning system (EWS) is demanding to predict the slope movement project. Time Domain Reflectometry (TDR) has been resort to monitor slope movement in a variety of geotechnical settings including highway cuts and rail beds. Until now, the interpretation of TDR results for detecting slope movement and identifying the location of shear planes has been limited to visual inspection of the plots of cable reflectance versus distance along the cable. Geotechnical applications of Time Domain Reflectometry (TDR) are continuing to develop and usage is increasing, particularly for monitoring subsidence over active and abandoned mines and monitoring slope movement. Assessing the stability of slopes is a difficult task that requires a strict approach. This paper starts by presenting a scope of slope movement factor such as soil water content, ground water level and ground movement. The physical and mechanical behaviour of the soil and the saturation state are complex and required simplification in order to understand how water reduces the shear strength of soil. Time Domain Reflectometry (TDR) is one of the non-destructive testing methods (NDT) that could be used to assess the soil water content without much disturbing on the original condition of the soil. Benefits of using TDR in slope movement monitoring are minimal disturbance on soil sample during sampling process and continuous monitoring of soil saturation condition at site. © 2016 Author(s).
