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 [19].
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].
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].

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