Hydrogeology

Geophysical measurements yield data of layer thicknesses of aquifers and of the their boundaries. Depth and location of groundwater can be determined. 

Resistivity sounding

Morphology of a layer boundary gravel-clay within an area of several square kilometers, a revealed from resistivity depth sounding. The 3D-block diagram shows a pronounced channel system.

Geoelectric localization of a sand channel (green-yellow for high resistivities) within clays. Layer modeling further determined the 3-dimensional geometry.

Former meander channel filled up with fine sediments. 212 resistivity depth soundings.
