Observation and Modeling of Cascade Processes at the Reissenschuh (Schmirn, Austria)
Supervising board members: Barbara Schneider-Muntau, Bernhard Gems, Margreth Keiler, Martin Rutzinger, Thomas Zieher
The natural hazard process of deep-seated gravitational slope deformation (DSGSD) poses multiple threats to infrastructure in mountain regions, but also secondary processes like rockfall and debrisflow within the DSGSD cascade system have to be considered. The PhD project of Johannes Branke applies an interdisciplinary approach to investigate these process cascades linked to DSGSDs in an alpine catchment. As primary investigation site the DSGSD below the summit of Reissenschuh (Schmirnvalley, Tirol, Austria) was chosen. Existing earth observation time series will be extended using differential global navigation satellite system (DGNSS), terrestrial laserscanning (TLS) and photogrammetry. The resulting displacement time series in combination with geotechnical field and laboratory analyses will be applied to geotechnical process models identifying triggers and assessing slope stability. Regarding the secondary processes numerical modelling of gravitational mass movement processes and debrisflows with their respective run-out events will be conducted.
