Geophysical methods are beneficial for mapping of possible fresh and salt water intrusion in coastal regions. As it well knows, possible seawater intrusion might have negative impacts on groundwater quality and agricultural soil. In this study, a geophysical survey were performed at Trabzon, Eastern Black Sea, Turkey in order to determine possible seawater intrusion and to reveal the shallow underground. These survey consist of frequency domain electromagnetic method (FDEM) and electric resistivity tomography (ERT). In this context, FDEM and 2D ERT data were collected along 7 profiles and 4 profiles at the selected area, respectively. 2D section were created from FDEM measurement profiles. In addition to, 2D sections and 3D image were obtained from ERT measurements. At Trabzon, geophysical survey revealed saline/fresh water zones and shallow underground in the investigated area.
