Abstract

A

One of the main tasks of geoelectrical techniques in their application to hydrogeological objects is the detection of aquifers with fresh water and the delimitation of such aquifers from impermeable or salt‐water‐bearing beds. In practice it frequently occurs that intercalated clay horizons divide an aquifer into several “storeys” of various thicknesses.

The present paper deals with an aquifer consisting of two storeys (sand and gravel), above a substratum of good electrical conductivity (clay, salt water). By means of a set of 72 computed master curves, the possibilities of interpretation of geo‐electrical measurements above such a substratum are examined with respect to the specific resistivities of the overburden and the intercalated clay horizon. Different thicknesses of the two groundwater storeys are considered. The result gives an idea of the extent to which geoelectrical measurements may help to elucidate hydrogeological conditions; it also provides the geophysicist with practical hints for the performance and the interpretation of such measurements.
