This study created a groundwater flow model using Groundwater Modeling System (GMS) software integrated with MODFLOW to create a steady-state groundwater flow model for the Ibeju Lekki Local Government Area of Lagos State. Aquifer parameters (hydraulic conductivity, transmissibility), groundwater recharge data (rainfall/climate, recharge rate), topography, and a hydrogeological map were acquired from both public and commercial organisations. The contour of the head solution demonstrates that the groundwater flow of the research region flows from the north-east, where the value of the head is high, to the south, where it also declines.The head expresses the potential energy of the groundwater per unit weight and thereby influences the direction of the groundwater flow.
