Electromagnetic induction (EM) techniques are used in recharge/discharge studies by providing measurements of the apparent electrical conductivity of soil profiles. This booklet provides a summary of EM techniques that are most widely used. A number of case studies are presented which demonstrate the applications of the techniques to field problems.
