| Zusammenfassung |
| The presented questionnaire study summarizes an evaluation of approaches,
techniques and parameters of slope-instability investigation and monitoring
of their occurrence, reliability and the applicability of the monitoring
techniques for early warning. The study is based on information collected
from 86 monitored landslides in 14 European and Asian countries. Based on
the responses, lidar ALS (airborne laser scanners), geophysical logging, aerial photographs,
resistivity surveying, GB InSAR (ground-based synthetic aperture radar
interferometer) and the refraction seismic were considered
the most reliable methods for investigation of structure and character of
landslides. Especially lidar ALS and geophysical logging were ranked high
despite their application at relatively few landslides. Precipitation
amount, pore-water pressure and displacement monitored by wire
extensometers, dGPS and total stations, followed by air temperature and
EM-emissions monitoring and displacement monitored by the TM 71 crack gauge
were considered the most promising parameters for early warning. |
