space along 100 meter was used to survey the data with 2.5 meter electrodes spacing. In the survey, the geoelectrical resistivity line was crossed with the monitoring well which had gamma ray data. The nearest line was adjusted to be 2 m away from the well to avoid affect of the well in the geoelectrical resistivity reading.
Electrical resistivity (also called specific electrical resistance or volume resistivity) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current.A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ ().
Resistivity Methods. Surface electrical resistivity surveying is based on the principle that the distribution of electrical potential in the ground around a current-carrying electrode depends on the electrical resistivities and distribution of the surrounding soils and rocks. large differences in geoelectrical section, particularly at
Electrical resistance surveys (also called earth resistance or resistivity survey) are one of a number of methods used in archaeological geophysics, as well as in engineering geological investigations.In this type of survey electrical resistance meters are used to detect and map subsurface archaeological features and patterning.

to be horizontal. The resistivity of a material is a measure ofhow well thematerial retards ﬂow electrical current. Resistivities vary tremendously from one material to another. For example, the resistivity of a good conductor such as copper is on the order of 10 8 m, the resistivity of an intermediate conductor such as wet topsoil is 10 m, and
Resistivity is the resistance per unit volume. Consider current flowing through the unit cube of material shown to the right: resistivity is defined as the voltage measured across a unit cube's length (Volts per metre, or V/m) divided by the current flowing through the unit cube's cross sectional area (Amps per meter squared, or A/m 2).
