Abstract

Submarine groundwater discharge (SGD) is an integral part of coastal hydrology. Freshwater springs in the tidal region at Elim Beach are the result of tidal forcing of the confined aquifer that runs under the beach and under the tidal zone. In a recent paper by Holliday et. al., the extent of the aquifer inland has been estimated using a simple hydrological model. This model assumes negligible phase lag or attenuation of the tidal forcing. In this paper, we compare the results of the simple model with a more accurate model that does not ignore any phase lag or attenuation. We use this model to provide bounds on model parameters and verify the accuracy of the simple model.
