Geological 3D-models – NW Switzerland at various scales
Horst Dresmann
For more than 20 years, the AUG has been developing geological 3D-models which can be employed as tools for dealing with many issues in the areas of groundwater, geothermal energy, infrastructure planning and civil engineering (Figures 1-3).
Sound geological knowledge and modeling experience form the basis for the development of geological 3D-models, which can consistently map complicated geological layering and structural conditions. Together with Geographical Information Systems GIS and groundwater models, ideal conditions for quantitative hydrogeological investigations can be created.
In addition to the geological 3D-model for the Basel region (20 x 30 km) (Figure 1), in scope of numerous research projects the AUG has created local- and, in cooperation with project partners, regional-scale geological 3D-models (Figures 2 & 3).
