The techniques used were:
This combination of electrical and electromagnetic (EM) techniques is a common application in investigations of shallow Quaternary deposits, and has been used successfully in a variety of recent BGS projects.
The image below is an example of an ERT (electrical resistivity tomography) geophysical cross section across the floodplain/valley floor and the adjacent hill slope.
