LOW-PROFILE BARRIER ISLAND OVERWASH AND BREACHING IN THE GULF OF MEXICO

[摘要] An analysis of 17 tropical cyclone impacts along barrier islands in the Gulf of Mexico has led to the following conclusions: 1) tropical cyclones are the primary mechanism of barrier island overwash and breaching, 2) landward-directed and seaward-directed overwash flow can breach barrier islands, 3) storm track orientation to the shoreline controls the direction of barrier island breaching, 4) shore-normal and right-oblique hurricane impacts breach barrier islands by landward-directed overwash flow, and 5) left-oblique hurricane impacts breach barrier islands by seaward-directed overwash flow.
