Electrical Resistivity Monitoring Primer

Electrical resistivity is a powerful geophysical method which can provide information which is relevant to hydrologists, geochemists, farmers, natural resource managers and civil engineers.  By using electrical resistivity in a monitoring mode  we can obtain information on how changes in the subsurface (e.g. movement of the water table, freeze/thaw, remediation progress and more).

This information can be used for both operational, regulatory and research purposes.  This primer provides a brief, non technical overview of some of the key concepts behind this method by first providing an overview of electrical resistivity and then discussing electrical resistivity monitoring. Note that this is also known as timelapse resistivity or 4D resistivity.

This primer is targeted at non geophysicists who have an interest in what electrical resistivity monitoring is and whether it possibly could help them in their efforts. This group could include hydrologists, remediation professionals, agricultural scientists, water resource professionals, and in general anyone who wants to know what is happening in the subsurface.
