Coastal Bluff Recession and Impacts on Littoral Transport: Special Reference to Montauk, NY

摘要

Recession of coastal bluffs supply the initial sediment to the littoral zone along the south shore of Long Island, NY. Analysis of profile data collected as part of the Atlantic Coast of New York Monitoring Program indicated volumetric recession rates vary between headlands and coves along the Montauk province ranging from 1.0 m~3/m/yr to 19.6 m~3/m/yr. Stabilization of the bluffs through vegetation, drainage control, slope reduction and toe armoring has reduced the amount of sediment supplied to the littoral drift through recession.
