Barrier islands serve as crucial buffers for coastal communities, mitigating the impacts of storms, hurricanes, and sea-level rise. The geomorphology of these islands significantly influences storm effects and recovery processes, which, in turn, are shaped by subsurface geological and hydrogeological factors. This study examines the interplay between subsurface conditions, island geomorphology, and human development on Padre Island in Texas. Our investigation utilizes frequency-domain electromagnetic (FDEM) and time-domain electromagnetic (TDEM) surveys to analyze apparent electrical conductivities, revealing the intricate connections between subsurface characteristics and surface morphology of barrier islands.
