Landslides cause fatalities and considerable loss each year in mountainous regions. With progressing climate change factors affecting landslides are projected to change in frequency and magnitude. CAUTION will focus on different landslide types and it is expected that climate change will influence the landslides processes due to glacier retreat, permafrost degradation, slope foot erosion due to flooding, extreme precipitation and snow melt periods, as well as extreme temperature fluctuations. Regarding possible adverse effects of mountain hazards to communities, exposure assessment poses particular challenges in climate change research, in policy development and governance. Thus, CAUTION will focus on exposure of societies affected by landslides on a local level, and determining the physical, economic, institutional and social aspects as well as the interactions between these. It will allow quantifying ex-post the spatio-temporal dynamics of exposure taking specific landslide types as an example as well as an ex-ante scenario-building to allow for identifying possible future risk pathways on a local and regional level. CAUTION is on the cutting edge of multiple disciplines (geosciences, climate sciences, economics, political sciences, disaster management) and develops deeper insights into the human-environment dimension of hazard management in mountain areas, and as such into an integrative assessment of climate change adaptation. The project will advance our understanding i) of critical meteorological conditions triggering landslides, and on how climate change will modify those mountain hazards, ii) on hazard and risk assessment strategies, as well as forecast capabilities, iii) on exposure of societies affected by landslides on a local level, by determining the physical, economic, institutional and social aspects as well as the interactions between these. Beside CAUTION will foster the collaboration and engagement between the scientific community and policy stakeholders.

DRAGON is a follow-up project to VIGILANS and addresses the open questions that arose from VIGILANS to achieve an improved hazard analysis of slow slope movements for society. To determine the hazard potential of different deformation types, the depth and geometry of the fracture surface (sliding surface) is determined using the vector inclination method (VIM) based on 3D motion vectors obtained by combining 2D InSAR data (Sentinel-1 and TerraSAR-X) with ground-based InSAR data (GB-InSAR). In addition, Envisat and Sentinel-1 analyses are used to retrospectively determine the slope deformation trajectories for the two selected active slope movements (Steinlenen & Malgrube, Tyrol) for the past twenty years. This allows to assess whether the documented spontaneous rockfall events are directly coupled to the progressive failure of the large slope movements. Time series analyses will identify potential acceleration phases and will be compared with meteorological data series. Due to the known, complex motion behavior of deep-seated slope deformations, it is important to adopt a research approach that integrates multiple technologies and platforms. DRAGON combines for the first time satellite data with ground-based remote sensing (GB-InSAR, TLS, tacheometry, drone photogrammetry) and in situ measurements (D-GNSS, convergence measurements, seismic monitoring). The goal is to create a three-dimensional kinematic model for the two large slope movements that is as accurate as possible and reflects the results of the different measurements and also allows a forecast of the further course of the slope failure. The results form an important contribution to the process understanding of deep slope deformations and can be applied to a large number of mass movements of this type.

Project Owner: Slovenian Geological Survey Project Phases: -) Field work and sampling (either from drill core or from outcrop) -) physical preparation -) Extraction of cosmogenically produced Al and Be from 10 samples collected in Slovenji Gradec basin -) age calculation, reporting The aim of this project is the investigation of sediments in the basin filling of the Sloveni Gradec basin, in particular, the attempt to determine the depositional period of the sediments. For this purpose, 4 boreholes are drilled by the project partner (Geological Survey of Slovenia), which recover sediments from the deeper parts of the basin. The sedimentological record by the project partner will be complemented and numerically constrained by an age model from the Laboratory for Cosmogenic Nuclide Extrusion (laboratory homepage:; IAG, BOKU). If carried out successfully and with suitable sediments, tectonic activity in the Sloveni Gradec basin can be calculated. This information will be further used for the risk assessment of the Krsko nuclear power plant. Translated with (free version)
