Slope stability analysis with different advanced soil constitutive models
Supervising board members: Barbara Schneider-Muntau, Martin Rutzinger

The purpose of this project is to integrate advanced soil constitutive models, such as hypoplasticity and barodesy, with the strength reduction method for slope stability analysis and apply it to a real-life case study of a slope.

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.

Dating of rock slope failures and rock scarps using novel and classical optical dating techniques
Supervising board member: Michael Meyer

Recently, a new Optically Stimulated Luminescence (OSL) dating approach, making use of the remnant luminescence signal in rock surfaces, has been successfully applied to geological features and archaeological artefacts, which have previously been considered as being not amenable to numerical dating. The PhD project of Stephan Fuhrmann is based on such an OSL rock surface dating approach and will combine this novel dating approach with a fundamentally new way of reading out the optical information (and thus age) from rock surfaces containing feldspar minerals (i.e. 2D mapping using a EMCCD camera set-up). This state-of-the-art optical dating approach is combined with classical geological fieldwork to determine the age of rock slope failures and rock scarps and to observe bed load transport in bedrock river channels and braided (i.e. glacier influenced) rivers.

Changing debris cover on Eastern Alpine glaciers: Quantification and hydrological impacts
Supervising board member: Stefan Achleitner

Glaciers and permafrost are retreating in the wake of climate change and are causing a rapid transition from glacial to deglacial conditions with highly intensified geomorphic processes in the proglacial zones and freshly deglaciated areas. The Hidden.ice project investigates the hydrological impact of supraglacial debris deposits in the transition zone from glacier ice to proglacial areas in Austria. The PhD candidate Clemens Hiller focuses his research on the dynamics of bedload transport and the coarse sediment budget in the forefield of the Jamtalferner glacier (Silvretta range, Austria). By capturing present proglacial sedimentary dynamics and the behaviour of high alpine fluvial systems in rapidly changing environments, subsequent future developments can be anticipated.

3D-tectonic model and numerical modelling of the Inntal shear zone – seismic hazard of geothermal energy use in the Inn valley, Tyrol
Supervising board members: Hugo Ortner, Barbara Schneider-Muntau

The amplified climate crisis and the need for security of supply without imported fossil fuels, enhance the longing for self-governed, autonomic energy supplies and sustainable energy sources. In Austria, the potential for geothermal energy use is often unknown and widely unused. The GeoEN Inntal project (funded by ÖAW), an integrative approach to connect science and local public, delivers the geological and hydrological framework for future geothermal energy projects (from deep to shallow geothermal energy), in a highly complex tectonic setting, like the lower Inn valley. PhD candidate Simon Hinterwirth focuses on geometric and mechanic numerical modelling of the Inntal shear zone, a large- scale strike-slip fault, with multiphase activity. This integrated modelling approach aims to address recent seismicity and potential changes in stress conditions to fault zones and reservoir rocks, to prevent re-activation, and to reduce induced seismicity.

Estimating Snow Water Equivalent in heterogeneous terrain - On the search for good practices in Cosmic Ray Neutron Sensing
Supervising board members: Johann Stötter, Martin Rutzinger

The Snow Water Equivalent (SWE) has a substantial role in hydrological models and forecasts. Up to now conventional measurement systems sense SWE only at point scale, which does not match the spatial resolution of models or complementary remote sensing products. Negligence of the spatial variability of snow pack properties commonly results in inaccurate model input. The PhD candidate Nora Krebs who is part of the Cosmic Sense - DFG-Forschungsgruppe FOR 2694 at the University of Potsdam investigates the applicability of above-ground Cosmic Ray Neutron Sensing (CRNS) to the monitoring of SWE dynamics. The method has a footprint of several hectares which meets the resolution requirements of most models and remote sensing products. The technique can measure SWE independently of snowpack variability, which makes it ideal for an application in Alpine terrain. Current investigations are focused on a network in the proximity of Innsbruck.

Causes and consequences of extreme geological perturbation events in the upper Traun catchment area (Salzkammergut)
Supervising board members: Michael Strasser, Jasper Moernaut, Tobias Hell

Mountainous regions are among the most sensitive to climate change, global warming and natural hazard processes of different causes (e.g. meteorological, hydrological, and/or geophysical) and potentially-cascading consequences. Geological archives, such as lakes, especially Lake Hallstatt and Lake Altaussee within the Salzkammergut, enable to assess various hazards on a Holocene time scale from local-scale events (e.g. debris flows, rockfalls or avalanches) to large-scale regional events (e.g. earthquakes, droughts or floods). The interdisciplinary PhD is multi-funded (e.g. ÖAW-DOC-Fellowship) and allows PhD candidate Marcel Ortler to investigate the “Causes and consequences of extreme perturbation events in the upper Traun catchment area”. Particularly to reconstruct past occurrence of meteorological, hydrological and geophysical hazards, anthropogenic impacts, and their complex interactions, and  to gain advanced understanding of magnitude frequency relations on relevant time to reduce epistemic uncertainties in natural hazard assessments.

Development  of an ultrawide band radar for snow research measuring systems for the acquisition of stratigraphy and snow erosion in the field of avalanche
Supervising board members: Barbara Schneider-Muntau, Alexander Sutor

The snowpack structure and individual layers are an important component in the assessment of avalanche danger. In the field of avalanche dynamics, no data on the stratigraphy and snow erosion in motion are currently collected. The dissertation aims to develop a suitable measurement system and measurement network that records exactly these data. Radar technology already offers the possibility to record snow depths and velocity. Because of these existing measurements, the development will therefore focus especially on radar technology to record these data. Stratigraphy and snow erosion will not only be used selectively, but will provide data acquisition over the entire avalanche area.

Assessment of dynamicstability problems of embankment dam structures on micro- and macro-scale level, employing a coupled DEM-SPH approach
Supervising board member: Barbara Schneider-Muntau, Wolfgang Fellin, Bernhard Gems

Actual activities within net-zero ambitions require the construction and safe design of embankment dams for hydroelectric storage and pumped storage facilities. In recent decades, the selection of adequate methods to assess permanent displacements from failure states triggered by seismic loading has been intensively and controversially discussed. A new approach, coupling the Discrete Element Method (DEM) with Smoothed Particle Hydrodynamics (SPH) for assessing permanent displacement from seismic loading, shall be developed to overcome limitations from existing analytical methods. This also includes confirming the applicability of such an approach through element test simulations focusing on consolidated triaxial tests under drained and undrained, and monotonic and cyclic loading conditions.

Requirements for the longevity of landslide dams in the Alpine region from a geotechnical and hydraulic perspective - Case-study-based data survey, modelling and hazard assessment
Supervising board members: Bernhard Gems, Marc Ostermann, Barbara Schneider-Muntau, Michael Strasser, Markus Aufleger

Landslide dams are recognized as the natural phenomena occurred when a landslide blocks a watercourse in narrow valleys causing the formation of a lake upstream of the landslide deposit. Detailed field studies on single cases and inventories are accounted as two approaches dealing with this phenomenon. In the PhD project of Roshanak Shafieiganjeh a GIS-based inventory of Eastern-Alps landslide dams including 73 cases is created. In the rest of this project, the main focus will be on numerical modelling of the Obernbergersee landslide dam. The leading aim will be to reconstruct the internal structure of the dam based on the geotechnical properties and hydraulic field measurements. At the end, the flood hazard due to the possible failure of the dam will be assessed.

Hidden hazard named liquefaction
Supervising board members: Barbara Schneider-Muntau, Japer Moernaut

For constructions built on or within sandy soils, soil liquefaction is a serious issue. To have an overview of our research planIn order to predict the possibility of liquefaction, some theoretical investigation with Hypoplasticity and Barodesy constitutive models will be done and then would be calibrated by experimental tests in the second step. And finally verifying the findings by a series of numerical modeling.

Continental indentation in analogue models: Internal deformation and tectonic evolution of the Dolomites Indenter
Supervising board members: Hugo Ortner, Hannah Pomella, Barbara Schneider-Muntau

At present, the relationship between deep-seated mantle dynamics and their control on the geometry and internal deformation of the Adriatic Indenter remains unsolved. In the PhD project of Anna-Katharina Sieberer (FWF funded), a compilation of existing and a collection of new and comprehensive structural data along major faults, in combination with crustal to lithospheric scale physical analogue modelling sets out to unravel the 4D tectonic evolution of the eastern Adriatic Indenter, the Dolomites Indenter. Findings from physical analogue modelling will be combined with basic numerical modelling in order to get an integrated understanding of the continental indentation process. As part of the AlpArray initiative, with its focus on seismological investigations of the subsurface, this project provides crucial data for an integrated geodynamic model of Alpine convergence.
