Abstract

An asymmetric freshwater lens is shown to exist in a long narrow coastal barrier beach bounded on 1 side by a salt water lagoon and on the other by the ocean. Field measurements of ground-water specific conductance and water table elevations show the lens to average approximately 17 ft (5m) in maximum thickness and to be thicker on the side toward the lagoon. The asymmetry is apparently due to an effective mean sea level higher than actual mean sea level on the ocean side which occurs because of tide and wave action on a sloping ocean beach. -from ASCE Publications Abstracts
