If the stable opposing electrode method is applied, GSS will change its behaviour towards conductive after reduction, maintaining very low resistivity, but Cu synthesized GSS exhibits little change decreasing the bulk conductivity form 7.
The Wenner Four Point methos, is the most frequently used soil resistivity measurement method in electrical engineering applications.
Graphically,electrical resistivity readings are increase with a decreasing moisture content, reason being for a low soil moisture content there is less ionic mobility of electrons and hence higher the resistance.
The surface resistivity of the sample layer is increased with the increase of injection pressure, and the resistivity of subsurface and core decreases with the increase of injection pressure.
stabilized resistivity in these materials with dual-phase fillers.
Geophysical techniques study the contrast in the physical properties of the different units in the subsurface such as velocity, electrical resistivity, (conductivity), acoustic properties, subsurface geology and the environmental conditions [8][7][15][18][4] and they can provide some of the information required to delineate those materials in the subsurface space such as the overburden thickness, horizontal and vertical lithologic extents, depth to water table, fault zones [22].
This type of processing is made possible by Res2Dinv software and it is recommended to apply when a subsurface resistivity changes in a sharp manner what is expected in the case of presence of an adit, flysch and near surface soils.
Another is the B-C compound which can increase the resistivity of the film.
The progressive failures in the once-effective IX cartridge will result in undesired changes to the level of contaminants present within the water and the resulting resistivity (see Figure 1).
The final results of the modeled and interpreted resistivity data are presented in the form of geoelectrical sections.
One of tools for mapping of electrical resistivity data is geostatistical methods.
