Short summary
Pre-investigation for tunnelling below water passages is a challenging task with the main objective of locating fracture zones that lead to low rock quality and thus reduced stability. An inversion approach was tested that combines different geophysical methods to improve the reliability of the results. A fracture zone and previously unknown sedimentary deposits were successfully detected. Synthetic studies pointed out the importance of 3-D effects and model resolution properties.
