Abstract

ABSTRACT

Electromagnetic (EM) surveys using the horizontal coplanar loop (‘Slingram’) geometry have been successful in the location of karst aquifer systems in limestone areas of Germany and the Mediterranean. In spite of the rapid changes in shape and resistivity of karst pipes, correlations of significant EM minima can be made by reference to the main structural directions. The EM results have often been verified by drilling. EM prospecting need not be confined to limestone areas. It can be used on all hard rocks where faulting has created vertical zones with a resistivity contrast to the undisturbed rock.

EM siting of wells has proved successful in water‐supply schemes for several places. This method is now being applied as a routine, fast and low‐cost procedure to tap ground‐water resources in hard‐rock areas.
