Managing Geohazards
Our society worldwide is repeatedly the victim of destructive natural forces due to extreme natural events. High economic losses, the loss of human life and the endangerment of social structures have to be overcome regularly. Predicting the effects of these forces in terms of their extent, space, time and intensity and minimizing their consequences is a central, interdisciplinary challenge at a local, national and global level. The intensities of extreme meteorological natural events (storms, storm surges, heavy rainfall events) are increasing, but geophysical natural events (earthquakes, volcanic eruptions) also regularly occur with varying degrees of damage. Complex chains and cascading catastrophes that follow an initial extreme natural event are often of no less intensity (tsunamis, mass movements) and cumulative in their extent. For this conference topic, it is planned to also address current scientific results in the form of short presentations and/or posters. Among others, the following topics will be addressed:
Natural hazards: environmental impact and landscape changes
Anthropogenic contribution to natural hazards in a changing world
Modelling: scenarions, predictions, uncertainties of cascading hazards
Hazard mitigation: geo-engineering, education and outreach
We welcome contributions on natural hazards especially on the above-mentioned topics and encourage expert colleagues to submit a short description of their planned conference contributions addressing one (or more) of these topics.
Making Water Supply Resilient for Future
Climate change, increasing urbanization and economic growth are all setting water resources under growing pressure. At the same time, expectations regarding the availability and quality of water are rising including in some regions rising reliance on groundwater for domestic and commercial-industrial supply and irrigation. Contributions and discussions in this thematic block address the challenges for future water supply to have sufficient water of adequate quality. They will show what water resources can be available to our societies and what strategies are needed to protect water resources today and for future needs.
Contributions are particularly welcome on the following aspects:
Methods for exploring groundwater resources
Influences of climate change on water resources
Anthropogenic substances in the hydrosphere
Strategies for protecting water resources

“Future of Mining”
Elisabeth Clausen is a Full Professor and Director of the Institute for Advanced Mining Technologies of RWTH Aachen University. Prior to that she was a Scientific Research Assistant at the Institute of Mining at Clausthal University of Technology, where she obtained her Doctoral Degree (Dr.-Ing.) in the area of Underground Mine Planning and Production Scheduling in 2013. After a subsequent post-doc period as Academic Counselor at the same institution, she was appointed as Full Professor and became Director of the Institute for Advanced Mining Technologies (AMT) at RWTH Aachen University in 2018.
The Institute for Advanced Mining Technologies develops technologies for the automation and digitalization of mining machines and processes to enable safe, efficient and responsible raw material extraction. An important core area of the institute is therefore the development of sensor technologies being able to cope with harsh mining environments, and corresponding algorithms for the generation, acquisition and processing of data and information along the entire data-information-value-chain. The challenging environmental conditions in mines place particularly high demands on people, machines, sensors and algorithms and require robust, connected and intelligent systems and solutions.

“Digital Twins for Subsurface Applications: Opportunities and Challenges”
Florian studied geology at the University of Tübingen with a focus on geophysics and applied geosciences, and performed theoretical and experimental work for his Diplom-thesis (M.S. equiv.) at the ETH Zürich. After his studies, he worked for two years for the German Antarctic Survey (AWI) as geophysicist and overwintering team member on the German Antarctic research station Neumayer II. Subsequently, his combined interest in geophysical and geologic methods brought him to the Institute of Geothermal Resource Assessment, and subsequently to the University of Western Australia to pursue postgraduate studies in the group of K. Regenauer-Lieb, where he investigated the influence of structural uncertainties on the dynamic stability in geothermal flow fields. In 2014, Florian joined RWTH Aachen University as Junior Professor in “Numerical Reservoir Engineering” as a young research group leader within the graduate school Aachen Institute for Advanced Study in Computational Engineering Sciences. In 2018, Florian was appointed as Full Professor in “Computational Geoscience and Reservoir Engineering”.
The work in his group is focused on understanding the influence of uncertainties in subsurface property distributions, and the influence of these uncertainties on subsequent process simulations. This work has been applied to explore uncertainties in geothermal systems and carbon sequestration simulations, and his approaches to quantify and visualize uncertainties in 3D settings have been taken up in diverse areas, from modeling projects in geologic surveys to medical imaging.
