Tobias Schnepper is a doctoral researcher at section 3.4, “Fluid Systems Modelling”, at the GFZ German Research Centre for Geosciences. After completing his Master’s degree in “Geology” at the University of Bonn in cooperation with the Forschungszentrum Jülich, he started his research in Potsdam in August 2021. The focus of his work is on modelling hydrogeochemical processes in open-pit lignite mining lakes, associated waste rock piles and aquifers in connection with the realisation of hybrid pumped hydro power storages.
In his presentation, Tobias shared insights into the background, objectives and challenges of his ongoing research. In particular, the effects of dissolution and precipitation processes between minerals present and processed water on slope stability and water quality are of his interest. Initial simulations included both inverse models and non-dimensional reaction path models based on historical site data. These serve as a basis for more complex models, taking into account more recent chemical data.
