A finite element program, GROSEEP, was developed to estimate the groundwater seepage from the surficial aquifer into Indian River lagoon along a selected cross-section in Port St. Lucie, Florida. The model is a general purpose model and can be used at other cross-sections. Model results using a single layer indicate that groundwater seepage could be an important freshwater source into the lagoon. Sensitivity analysis using a three-layer model predicted that among other parameters the presence of windows in the clay layers could significantly affect seepage rates into the lagoon.
