Resistivity surveys are geophysical methods used to measure the electrical resistance of the ground. By sending an electrical current through the soil or rock, these surveys help identify variations in subsurface materials, such as water, minerals, or contaminants. The data collected can reveal important information about the geological structure and composition of an area. These surveys are commonly used in fields like environmental studies, geology, and civil engineering. They can assist in locating groundwater resources, mapping underground structures, and assessing soil conditions for construction projects. The results are often displayed as resistivity profiles, providing a visual representation of subsurface features.
