Long-term beach response to groin shortening, Westhampton Beach, Long Island, New York

Author

Summary, in English

The groin field built at Westhampton, Long Island, NY, in the 1960s and early 1970s has functioned as intended in protecting a once-vulnerable 4.8-km long segment of barrier beach that had experienced repeated breaching. In 1996-1997, a tapered groin transition to the west was created. The tapering included placement of fill in the existing groin compartments and on the adjacent beach. The combined groin tapering and beach fill have been successful, and the renourishment interval for the beach to the west of the groin field has been extended. As a result, concepts have been put forward regarding shortening of all the original groins. The objective of the present study was to evaluate options involving groin shortening to supply the down-drift beach. The study evaluated not only the evolution of the shoreline, but also the beach and dune interaction for decade-long simulations that include storms.
