Today, one of the most effective methods in exploring and searching for underground water resources is the use of geophysical methods, especially geoelectric methods, one of its subsets is the special resistance method. This method is used in the study of vertical and horizontal discontinuities in the electrical properties of the earth, as well as in the exploration of anomalous conductive masses. Today, the specific resistance method is widely used in hydrogeological studies and researches in order to investigate and explore underground water tables.Geophysical studies (using specific electrical resistance method) were conducted to investigate the condition of underground water layers in the area of a residential structure located in Javanroud city on 3 profiles with two-dimensional method and Wenner-Schlumberger arrangement. The purpose of conducting these studies is to investigate the possibility of water infiltration from around the desired building to under the building. Modeling and interpretation of the studies done by two-dimensional electrical tomography method and by Res2dinv software. The results of the studies were completely consistent with the results of the drilled boreholes.
