Abstract
Models and simulations enable us to predict how processes in the geosphere might unfold in the future, taking into account physical and chemical laws. They are the only way to test future scenarios and hypotheses and to evaluate how a final disposal site will develop over a period of one million years, e.g. by quantifying potential radionuclide migration in the hydrogeological system of the containment providing rock zone. The degree of reliability of the models is derived from comparisons with laboratory tests, data from boreholes, underground laboratories and natural analogues.
About Michael Kühn
Michael Kühn studied chemistry and geology. He received his doctorate in geochemistry from the University of Bremen in 1997 and habilitated in hydrology at the Technical University of Hamburg-Harburg in 2003. Michael Kühn is Director of the Department of Geochemistry at the GFZ Helmholtz Centre for Geosciences in Potsdam, where he heads the Section Reactive Fluids and Geomaterials. He is also Professor of Hydrogeology at the University of Potsdam. His research focuses on investigating the behaviour of water and other fluids in the sediments and rocks of the geological subsurface. In particular, he quantifies geochemical fluid-rock interactions using simulations of coupled processes.
