Multi-sensor instrumentation for monitoring landslides
Landslides are a type of natural hazard that may lead to loss of life and assets on a large scale. Being of national and international concern, the development of precise monitoring means for detection and reporting of landslides in real-time is of prime importance. Precise, real-time detection of landslides can contribute to the design of more effective and timely emergency response efforts in the face of the oncoming disaster. Urged by this, the OASYS project aimed to develop an integrated optimisation of landslide alert systems. This could assist in the avoidance of loss of life, the minimisation of destruction of property and the disruption of transport. In the long run, it would contribute, not only to the conservation of Europe's natural resources, but also to the economic advancement of poor regions. The project focused on observation methods for detection of potential landslides, continuous monitoring of critical areas and gathering of real time information about actual risk. Part of the project work involved the development of an advanced evaluation tool for landslide monitoring on a local scale. GEODATA and TU Wien, project partners, joined forces and generated a robust multi-sensor system for landslide monitoring. The advanced evaluation tool comprises a piezometer, an inclinometer, a surface extensometer, three tilt meters and six accelerometers. Having been installed in a suitable location in the opencast Hambach mine in Cologne, it was tested extensively. Accelerometer data collected was subject to further analysis to identify a possible relation between slope deformation processes and accelerometer signals in time and quantity.
