Die Fachsektion Hydrogeologie lädt Sie herzlich ein, Abstracts zur gemeinsamen FH-DGGV/DGGV-Session der GeoMünster "Past, Present, Future!", 22. – 25. September 2019, einzureichen:

8. Applied and Environmental Geosciences


8a) Geological and hydrogeological characterisation of reservoir rocks

Göbel, Patricia (1); Hinderer, Matthias (2); Schafmeister, Maria-Theresia (3)

1: Westfälische Wilhelms-Universität Münster, Germany; 2: Technische Universität Darmstadt, Germany ; 3: Universität Greifswald, Germany

In this session we want to initiate an interdisciplinary discussion about different and innovative methods and concepts to characterize reservoir rocks at various scales. The primary focus is on porosity and permeability, their quantification, heterogeneity and genesis and involves all rock types either suitable as reservoir rocks or as seals. Welcome are a priori geological concepts, outcrop-analogue studies, experimental lab set-ups in the laboratory, statistic concepts, modelling approaches and management systems. We are looking forward to interesting insights of research work as well as case studies, and in particular aim to bridge geology and hydrogeology.


8b) Deep subsurface groundwater systems

Keynote: Rafael Schäffer, TU Darmstadt, Germany: “The thermal provinces of Hesse, Germany”

Due to their unique chemical and physical properties deep groundwaters are of high geotechnical importance for the various subsurface use options, e. g. deep geothermal energy. Besides higher temperatures deep groundwaters are often characterised by higher salinities. Both higher temperatures and salinities may potentially cause problems for geotechnical applications of the deep subsurface. At least handling of deep groundwaters necessitates specific efforts and expenses, e. g. to prevent scaling and corrosion of technical components. While chemical compositions may vary even within one defined hydrostratigraphical unit, also profound knowledge of groundwater dynamics, regionally dominating forces and processes as well as hydraulical properties of subsurface faults and fractures is often limited. Hence, predictions of geotechnical use potentials of deep groundwaters at potential sites are complex and often unreliable.

We specifically, but not only, call for contributions that deal with collecting and analysing data of deep groundwaters and/or use numerical models to broaden the understanding of the chemistry as well as the dynamics, driving forces and dominating processes in the deep subsurface.


8c) Geosciences and safe nuclear waste disposal – current status and future directions

Liebscher, Axel; Borkel, Christoph; Magri, Fabien

Federal Office for the Safety of Nuclear Waste Management (BfE), Germany

Keynote: Thorsten Schäfer, University Jena: “State of knowledge in geological research on nuclear waste disposal”

The Site Selection Act (StandAG) re-started the German siting process for high-level radioactive waste disposal in 2017. Disposal is foreseen in deep geological formations and considers claystone, crystalline rock and rock salt as potential host rocks. Within the stepwise siting process, geological exclusion and assessment criteria and minimum requirements are applied, surface and subsurface exploration programs are executed and preliminary safety assessments are performed.

This session welcomes contributions on current status and future directions of the different geoscientific disciplines, like geophysics, geochemistry, mineralogy, geomechanics, geomicrobiology as well as geological, relevant for safe nuclear waste disposal. Topics may include, but are not limited to, advances in exploration, monitoring and modelling tools and approaches, fundamental and applied process understanding, THMC(B) coupled modelling, experimental and field studies, safety assessment strategies or disposal concepts.
