Abstract:

Groundwater accumulating in the pores, cracks or cavities of underground rocks can be of high quality and in significant quantities. In many countries, groundwater is used as basic drinking water or in agricultural irrigation and in industry. The use of geophysics for mapping of groundwater resources and determining fresh, salty, and polluted wetlands has grown enormously in recent years in parallel with the development of geophysical devices and the improvement of software. General information is given about the use of geophysics for groundwater exploration and groundwater pollution studies in this study. The method that provides the most information in groundwater research and therefore the most used method is the electrical resistivity method. This study explains this method and its use in groundwater exploration. In addition, field examples related to groundwater exploration and determination of salt-water intrusion area with electrical resistivity method for two different fields are presented. With the applications performed by the electrical resistivity tomography, the presence of the groundwater bearing layer and the salt-water intrusion were determined.
