Morphologic Modeling of Multiple Barrier Island Breaches for Regional Application

Abstract

This paper introduces a time-dependent model of regional barrier island breaching for multiple openings, whether as permanent inlets or as new breaches to the same bay. The model allows an arbitrary number of breaches and is forced by tide, storm surge, and wave set up. Limitations on the hydrodynamics, hence calculated breach evolution, are those associated with the Keulegan inlet model. The model includes possible closure or limited breaching by shoaling of the breach channel by longshore transport. Capabilities of the multiple breaching model are examined through eight sensitivity tests.
