Abstract

Evolutionary patterns of a tidal inlet and its adjacent barrier islands are identified via 10 years of remotely sensed data, hydrographic surveys, and a morphological numerical model. A cyclical geometric adjustment of the inlet to dredging of its navigation channel indicates that the system is in stable equilibrium. The inlet has been experiencing a counterclockwise rotation likely caused by the growth of a spit and the presence of a terminal groin that restricts the inlet migration. As this rotation continues, the southernmost flood channel has been encroaching into the downdrift back barrier. Continued erosion along the estuarine shoreline could increase the vulnerability of an existing coastal roadway from the estuarine side.
