The electrical resistivity method, which is one of the most widely practiced geophysical prospecting methods, has in the past usually been applied to groundwater and underground resource exploration. The CSAMT/MT method has been used to identify groundwater exploration targets According to Srinivasamoorthy (2009), the important purpose of electrical surveys is to determine the subsurface resistivity distribution by making measurements on the ground surface. Exploration of groundwater requires a basic understanding of its position in the subsurface geological setup. Electrical Resistivity Method (ERM) is part of geophysical methods which used as preliminary step involve in any groundwater exploration. Because of this effect, groundwater is a good target for electrical and electromagnetic geophysical methods that measure resistivity. The resistivity of subsurface rock formations is one of the physical properties determined through the process of logging that is performed on most oil and gas wells, utilizing instrumentation inserted into the wellbore. These include groundwater exploration (Ayolabi, Folorunso, Eleyinmi, & Anuyah, 2009c), mapping subsurface structures (Khali, … As you know from our Groundwater Education Series , an aquifer is a natural underground … It utilizes direct currents or low frequency alternating currents to investigate the electrical properties (resistivity) of the subsurface. B y utilizing the apparent resistivity parameters, it is widely used in hydrology, environmental protection, engineering geophysical exploration, metal and non-metal mineral resources exploration.. 2. A geophysical evaluation using Electrical Resistivity method for groundwater exploration at the study area was carried out which involved the utilization of Vertical Electrical Sounding (VES) technique Electrical resistivity methods have been extensively used in a number of near surface explorations since the first application around 1830 (Parasins, 1962). The application of surface resistivity method however, can provide useful method for obtaining information on aquifer properties in It is used in groundwater studies to determine salinity. Vol. Well today, we're teaching you the best way we know how to find groundwater—Electrical Resistivity Imaging. The results confirmed that the 2D earth resitivity imaging technique is a useful tool for groundwater exploration in the Quaternary aquifer due to high resistivity contrast between saturated and dry gravel or sand. Vertical electrical soundings (VES) based on the Schlumberger configuration will be conducted at these selected sites in the community. However, the depth of exploration is much shallower. Twenty Schlumberger VES's with maximum current electrode spacing of 400 m were carried out in the coastal zone of Shalateen area at the alluvial fan of Wadi Rahaba. French, Russian,and German geophysicists are mainly responsible for the development of the theory and practice of di­ re¤t electrical prospecting methods. 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. 6, 2015, pp. B. The application, interpretation, and understanding of electrical methods requires a familiarity with the relationship between soil and rock characteristics and the resistivities obtained from electrical data.
