Pagination or Media Count:
A numerical model of barrier island breaching is presented that is based on an assumed rectangular breach form. Sediment transport is calculated at the bottom and sides of the breach as driven by the Keulegan one-dimensional inlet hydrodynamics equations. Longshore transport is included and can close a breach. Multiple inlets to the same bay can be represented. The model is validated by comparison to laboratory data and to measurements of the 1980 breach at Moriches Inlet, Long Island, New York.
