This study investigates the presence and spatial extent of saline water and seawater intrusion in the Subiya Peninsula, Kuwait, a region designated for the establishment of the new Silk City. We collected transient electromagnetic (TEM) data at 63 stations using a coincident loop setup on a regional, as well as local, scale. The data were analyzed through conventional 1D inversion techniques, including Occam and Levenberg&ndash:Marquardt methods, to create detailed resistivity models of the subsurface. Our findings indicate significant variations in groundwater salinity, with increased salinity towards the coast and partly decreasing resistivity with depth, suggesting a transition from brackish to saline water. In the northern region, close to the Abdali farms and Al-Raudhatain freshwater fields, groundwater remains fresher at greater depths, while in the south, saline conditions are encountered, occurring at shallower depths. Local scale analysis reveals potential saltwater intrusion pathways and highlighted geological features such as faults. A thorough understanding of the hydrogeological conditions is crucial, as saltwater injection for oil recovery is common in Kuwait, and may correlate with present-day seismic activity. These insights are critical for the sustainable planning and development of Silk City, emphasizing the necessity for further geophysical studies and borehole data to ensure construction safety and sustainable water supply management. This research provides a foundational understanding of the hydrogeological conditions essential for the successful implementation of the Silk City project and for groundwater management in northern Kuwait.
