Hydrogeophysical mapping with the transient electromagnetic sounding method

3rd EEGS Meeting, 1997
The transient electromagnetic sounding method is an effective reconnaissance exploration tool for mapping good conductors like day and salt water. In the Bredebro area in Southem Jutland, Denrnark, the method has been used for mapping an aquifer situated in a Tertiary valley system eroded out in heavy day.

The pulled array transient electromagnetic method

3rd EEGS Meeting, 1997
The mapping of subsurface resistivity structures using transient electromagnetic soundings, TEM, has gained an important role in hydrogeological investigations in Denmark. Regional mapping with TEM have produced resuits, which leaves no doubt as to the ability of the method to delineate freshwater sandy aquifers in well conducting hosts of Tertiary ...
