In this study, an attempt has been made to study the causes of ground subsidence in the refueling area of the Hamadan airport by means of two-dimensional electrical resistivity tomography method. In the study area, land subsidence has occurred in several places, which is clearly visible. It should also be noted that at a distance of about 1.5 km from the study area, there are two examples of aqueducts (their positions are marked on the aerial photo in relation to the study area) which should be taken into account in the investigations. A geophysical study (electrical resistivity tomography method) was conducted to investigate the causes of ground subsidence in the study area on 2 profiles perpendicular to each other by Wenner-Schlumberger arrangement. Modeling and interpretation of underground layers has been done by Res2dinv software.
