Detection and quantification of deep groundwater flow using 3-d geothermal modelling

Flow velocity and discharge rate of groundwater are of major interest in many geoscientific applications. However, it is particularly difficult to estimate these quantities in deep aquifers with normally little information. Groundwater flow can change the temperature field in the Earth's upper crust significantly. This fact is used to identify areas where the thermal regime is disturbed by water flow (e.g. Vasseur and Demongodin, 1995). We compared temperature-data (corrected for the diffusion of paleoclimate) from an extensive database of the GGA-Institute with results from a 3-D conductive simulation. The differences between these two data sets reflect well the assumed nature of the flow regime
