Abstract: Seawater intrusion is a common problem in coastal aquifers that can be exacerbated by extensive groundwater withdrawals and climate change. A complete understanding of the aquifer system along with its natural hydrogeology is necessary for its management. The creation of a conceptual model is important for comprehending and managing the coastal aquifer system and for future evaluations of groundwater contamination. In this paper a hydrogeological conceptual model was constructed using data from geophysical surveys, geological maps, and borehole information. The conceptual hydrogeological model makes it possible to evaluate how susceptible the aquifer is to saline intrusion from groundwater extraction.
