USING RESISTANCE MEASUREMENTS TO DERIVE GEOLOGICAL DATA

Using geoelectrical measurements, subsurface layers can be characterised according to their specific electrical resistance. The measurements are either performed on an ad-hoc basis as deep soundings or along measuring lines as vertical sections (geoelectrical 2D tomography). These methods can be used, for example, to locate gravel formations or aquifers and determine their thickness. Geoelectrical 2D tomography combined with the induced polarisation method can also be applied very effectively on contaminated sites, for example to determine and demarcate a landfill body. Other specialised application possibilities include groundwater prospecting, the examination of protective embankments and the location of karstic structures (in particular cavities) and permafrost.
