Beach Change Envelope - Coastal System Change at Fire Island, New York

Completed
By St. Petersburg Coastal and Marine Science Center May 1, 2019

Given the unique challenges in quantifying the extensive, yet variable impacts of Hurricane Sandy at Fire Island, we used a time series of beach profile data at Fire Island, New York, to define a new contour-based morphologic change metric, the Beach Change Envelope (BCE).

The BCE represents the portion of the upper beach that is likely to undergo direct storm wave impacts and respond in the subsequent days, weeks, and months after the events. Changes in BCE width and BCE height are extracted from the pre- and post-Hurricane Sandy profile time series and found to coincide well with established states of recovery. By capturing and tracking these distinctive changes in upper beach morphology at each state, the BCE offers a new way of characterizing beach response and recovery cycles at Fire Island and similar sandy coastal settings.

Coastal System Change at Fire Island, New York

Fire Island is a 50-km long barrier island along the south shore of Long Island, New York. The island is comprised of seventeen year-round communities; federal, state, and county parks; and supports distinct ecosystems alongside areas of economic and cultural value. In addition to providing resources to its residents, the barrier island also protects the heavily-populated mainland from storm waves...

Characterizing storm response and recovery using the beach change envelope: Fire Island, New York

Hurricane Sandy at Fire Island, New York presented unique challenges in the quantification of storm impacts using traditional metrics of coastal change, wherein measured changes (shoreline, dune crest, and volume change) did not fully reflect the substantial changes in sediment redistribution following the storm.

A Bayesian approach to predict sub-annual beach change and recovery

The upper beach, between the astronomical high tide and the dune-toe, supports habitat and recreation along many beaches, making predictions of upper beach change valuable to coastal managers and the public. We developed and tested a Bayesian network (BN) to predict the cross-shore position of an upper beach elevation contour (ZlD) following 1 month to 1-year intervals at Fire Island, New York. We
