Abstract
Distributed Fibre Optic Temperature sensing (DTS) system allows the monitoring of geo-hydrological changes of boundary conditions due to rainfall. Based on the heat transport in soils the temperature distribution is closely correlated with the presence and movement of water in soils. Therefore rainfall infiltration as well as the degree of saturation as common landslide triggers can be monitored in a distributed way. The advantage of continuous measurements over several kilometers of cable and its robustness allows a long-time and early warning monitoring for landslide occurrence. This paper represents the potential and installation of DTS for monitoring of infiltration processes and degree of saturation in soil. Therefore about 600 m cable were installed at two scientific interesting test sites in Austria. In total an area of about 1,200 m2 was instrumented. The results are based on natural and artificial rainfalls.
