Integrated geophysical methods used for groundwater studies in the Polda and Murray Basins

Abstract

Vertical electrical sounding (VES) and potential field methods, magnetic and gravity, have long proved useful in solving groundwater problems. Seismic methods have also been used, but are generally too expensive for practical surveys. In recent years, the TEM method has filled a gap in the geophysical armoury, extending the effective range of electrical methods to the 50?400 m depth range. We present examples of the joint use of VES and TEM methods in the Murray and Polda Basins.
