These notes are restricted to those geochemical methods which have been used to quantify rates of groundwater recharge. There have been two main approaches. The first involves the use of mass balances and mixing cell models, mainly using conservative (non-reacting) dissolved species. The methods range...

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.
