They lead to the development of special landforms, e.g. tunnel valleys. Tunnel valleys are widespread in (formerly) glaciated areas. They are eroded by subglacially flowing water. To investigate their genesis, it is necessary to model feedback mechanisms between the ice sheet and the subsurface. In the North German Basin, a possible spatial correlation between tunnel valleys and underlying salt domes was often observed. Partly, this was explained mechanically with the presence of faults. We want to investigate a different hypothesis for tunnel valley genesis based on the following geothermal argumentation: As salt better conducts heat than the surrounding rocks, the geothermal heat flux is augmented above.
