“…9) to induce an alongshore drift, the western waves are more energetic and have higher propagation coefficients. These results are also consistent with the field measurements that showed that western storms produce more changes in the profile of Carchuna Beach than eastern storms (Bramato et al, 2012). The morphological development of the Carchuna IPW, which decreases in width and size toward the east, is consistent with the hydrodynamically induced sediment transport trends.…”

“…variations in the sediment grain size. The steeper-sloping zones are correlated with larger proportions of coarser sediments (Bramato et al, 2012). The steepest beach slope is located at H6 and corresponds to an old river outlet at that location.…”

“…Although the SWAN model was previously applied to Carchuna and validated with data captured during a 7-day field survey (Bramato et al, 2012), we also compared the model results with the data obtained with the instrument moored in 2010 (Fig. 1).…”

“…One category measures a single morphologic proxy (e.g. shoreline position (Morton et al, 1995;Thieler and Young, 1991;Farris and List, 2007;Houser et al, 2008;Hapke et al, 2010Hapke et al, , 2016Bramato et al, 2012;Phillips et al, 2017) or dune height (Houser et al, 2008(Houser et al, , 2015Stockdon et al, 2009;Wernette et al, 2016)); whereas the other simplifies spatial information along a cross-shore profile to an averaged value (e.g. beach volume and slope) (Morton et al, 1994;Stone et al, 2004;Stockdon et al, 2007;Houser and Hamilton, 2009;Mathew et al, 2010;Scott et al, 2016).…”

“…In contrast to the timescales of event-driven changes which are fixed (i.e. the duration of the event, in days), and therefore straightforward to evaluate, recovery intervals themselves are temporally varying (days, weeks, months, seasons, years) depending on the degree of change (Wang et al, 2006;Mathew et al, 2010;Bramato et al, 2012) and cross-shore location (beach vs. dune), making the definition of the term itself limited to the interval of the study (i.e. recovery with respect to what reference point).…”

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. 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 quantifies changes to the upper portion of the beach likely to sustain measurable impacts from storm waves and capture a variety of storm and post-storm beach states. We evaluated the ability of the BCE to characterize cycles of beach change by relating it to a conceptual beach recovery regime, and demonstrated that BCE width and BCE height from the profile time series correlate well with established stages of recovery. We also investigated additional applications of this metric to capture impacts from storms and human modification by applying it to several post-storm historical datasets in which impacts varied considerably; Nor'Ida (2009), Hurricane Irene (2011), Hurricane Sandy (2012), and a 2009 community replenishment. In each case, the BCE captured distinctive upper beach morphologic change characteristic of these different beach building and erosional events. Analysis of the beach state at multiple profile locations showed spatial trends in recovery consistent with recent morphologic island evolution, which other studies have linked with sediment availability and the geologic framework. Ultimately we demonstrate a new way of more effectively characterizing beach response and recovery cycles to evaluate change along sandy coasts.Published by Elsevier B.V.
