resistivity method

[‚rē‚zis′tiv·əd·ē ‚meth·əd]
(engineering)
Any electrical exploration method in which current is introduced in the ground by two contact electrodes and potential differences are measured between two or more other electrodes.

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.
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 [26].
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 [3].
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 [5].
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].

Key words: seisImager, near-surface seismic refraction method, electrical resistivity method, reclaimed land.
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.
