Hydroinformatics: Software development for soil and aquifer system analysis
Significant advances in water research and new observational and computational capabilities and infrastructures (e.g. MOSES, TERENO, VISLAB, JUWELS) provide the opportunity to develop next generation of smart, data- and model-driven water monitoring systems. The software tools we develop are designed to support scientists worldwide in the analysis of larger and more complex systems and to enable the exploration of hydrological extreme scenarios and their effects.
The ENVINF-Hydroinformatic developer group focuses on method and software development for the process-based modelling and parameterization of coupled surface, soil and groundwater systems, as well as the transport of dissolved substances, flow with variable density, or mechanical changes in aquifer systems due to changing environmental impacts.
As a numerical tool for the simulation and prediction of groundwater conditions and interactions we use OpenGeoSys, a multi-physics code for porous media which is used in numerous THMC applications. Originally developed from Rockflow, OGS-6 now has a modular structure and provides a robust open-source framework (OGS) for the integration of additional simulation capabilities that build on and extend the numerical kernel.
Dr. Thomas Kalbacher is the head of the work group Hydroinformatics and deputy head of the department of Environmental Informatics. He received his PhD at the Eberhard-Karls-University Tübingen, for his work on object-oriented software development for geometric modeling of complex hydrogeological systems. His PhD was awarded with a two year Alexander v. Humboldt / JSPS Research Fellowship, which he spent as researcher and lecturer at the Okayama University in Japan. He is a staff member of the department since 2009 and his research interests include computational environmental system analysis with focus on software and digital workflow development for numerical high performance simulations of water quantity and quality in heterogeneous subsurface. His work is directly related to the investigation of the impact of climate change and hydrologic extremes on soil water and groundwater dynamics and the development model-driven monitoring concepts.
