| Zusammenfassung |
| Automatic monitoring of alpine mass movement is a major challenge in dealing with natural
hazards. The presented research project shows a new approach in measurment and alarming
technology for water level changes an debris flow by using a high-frequency Pulse Doppler
RADAR. The detection system was implemented on 3 places (2 in Tirol/Austria
within the monitoring systems of the IAN/BOKU; 1 in Dongchuan/China within the
monitoring systems of the IMHE/Chinese Academy of Science) in order to prove the
applicability of the RADAR in monitoring torrential activities (e.g. debris-flows,
mudflows, flash floods, etc.). The main objective is to illustrate the principles and
the potential of an innovative RADAR system and its versatility as an automatic
detection system for fast (> 1 km/h – 300 km/h) alpine mass movements of any
kind. The high frequency RADAR device was already successfully tested for snow
avalanches in Sedrun/Switzerland (Lussi et al., 2012), in Ischgl/Austria (Kogelnig et al.,
2012).
The experience and the data of the five year showed the enormous potential of the
presented RADAR technology in use as an independent warning and monitoring system in
the field of natural hazard. We have been able to measure water level changes, surface
velocities and several debris flows and can compare this data with the other installed systems. |
