Benefits and Flaws of a Resistivity Survey

What I'd like to study In this case study we will study what is resistivity and how resistivity measurement works using physical principles. I will also explore the potential advantages and possible defects of this technology. In addition, we explore the famous historical usage of this method. What is resistivity? Resistivity is opposite to conductivity. It measures the ability of a material to resist current flow. It is a property of a material and remains constant independently of the particular shape of the material, but it depends on the quality and density of the particular material.

In 1970, the Edgar Casey Research Foundation measured the resistivity of the soil around Sphinx. Resistivity is an archaeological method in the case where there is a difference or abnormality in the medium-to-moderate current region. Evaluate the resistance to the current of the medium to determine the possibility of embedding artifacts, internal objects, health objects, or garbage pits. As a result of the investigation, it turned out that there is a natural pocket in the limestone under the hind leg.

Resistivity measurement is an active geophysical technique that involves applying current to the surface of the earth and measuring the subsequent electrical response at the surface to determine the physical properties of the subsurface material. The general rule of resistivity testing is that material under different surfaces can be distinguished by different potentials. The material potential difference is determined by applying a known amount of current to these materials and measuring the induced potential. Ohm's law states that the voltage (V) of the circuit is equal to the current (I) multiplied by the resistivity (R) of the medium (V - IR).

According to Srinivasamoorthy (2009), the important purpose of electrical measurement is to determine the underground resistivity distribution by measuring on the ground. Based on these measurements, you can estimate the true resistivity of the ground. Ground resistivity is related to various geological parameters such as the content of minerals and liquids in the rock, porosity, water saturation and so on. Resistivity survey has been used for decades in hydrological geology, mining and geotechnical engineering surveys. Recently it is also used for environmental investigation.
