Physical parameters derived from field data (resistivity and thickness) were then correlated with available borehole data, this calibration is necessary as electrical resistivity method
being an indirect geophysical method cannot differentiate clearly between similar lithologies in different field conditions.
The high-density resistivity method
is a kind of array exploration method .
This was achieved with the use of the electrical resistivity method
. The electrical resistivity method
involved the use of current which is introduced into the ground through a pair of electrodes (current electrode).
Previous studies have shown that the electrical resistivity method
can be used to investigate engineering properties of soils and rocks [15-22], to monitor contaminants and delineate contaminant transport in soils [10, 23-25], and to detect defects and heterogeneity in the landfill cover material .
During the last few years there has been an increasing trend of employing the electrical resistivity method
in subaqueous areas for geological and environmental studies [1, 2] and underwater geological mapping .
Another potential application of the electrical resistivity method
is to compute the moisture content of concrete, although reliability of this method is still under question .
The resistivity method
has been widely used as a reconnaissance tool in groundwater investigations because it yields a good correlation between a terrain's electrical resistivity and its geology and fluid content with numerous successful case histories [3-9].
The resistivity method
is one of the oldest methods for surveying media to study the earth's structure [1, 2].

The vertical resistivity method
proved to be a very important method of groundwater prospecting.
The electrical resistivity method
was selected because the Resistivity meter is available being less costly more portable and the shallow nature of the basement rocks and the water table.
