The purpose of the survey was to find a tunnel used as production site for V1 rockets during WW2. Tunnel site investigation using resistivity imaging This highway tunnel construction was hindered by a large weak zone of clay and soft limestone easily visible in the resistivity imaging profile. Cave detection using the resistivity imaging technique. Cave detection using resistivity imaging. Using resistivity imaging for bedrock mapping in karst terrain.
Interesting example showing how well drill logs match the resistivity images.
Schnabel Engineering has drilled 30 wells along three resistivity imaging profiles. The location of the wells are plotted on the profiles and wherever the boring hit bedrock, a crossbar has been placed on the plot. This way it is easy to see how well the resistivity image correlates to the bedrock topography. Cave detection using resistivity imaging found the Sting Cave. This is the original Sting cave survey using resistivity imaging.
