Abstract
Geophysical methods can be helpful in mapping<br>potential areas of groundwater. Eletrical resistivity and<br>very low-frequency electromagnetic induction (VLF)<br>surveys were carried out at a site in the state of Minas<br>Gerais. The electrical resistivity and VLF data correlate<br>well, and vertical cross-sections generated from these<br>data helped map cavities in limestones.<br>The results of a improved technique to interpret<br>VLFdata are presented.
