Summary:
It is becoming increasingly important to carry out efficient geophysical investigations into the hydrogeological conditions in larger esker areas. These investigations are aimed at mapping the prerequisites for groundwater or mineral take-out or conditions for artificial infiltration. Today most of these investigations are carried out based solely on a few geotechnical borings, giving only a small amount of information about the subsurface conditions. We show that the combination of ground-penetrating radar (GPR) and continuous vertical electrical sounding (CVES) measurements will, in a relatively fast manner, cover larger areas of investigation, and thus provide a large quantity of information about the subsurface. The combination of GPR and CVES will give detailed information about the top layers (down to 10–20 m), and will also provide good characteristics of layers down to 50–60 m.
