This paper assesses both long-term and short term retreat as it can be extremely rapid. Long-term average annual cliff retreat is typically 2 - 5 m a-1 where cliffs have no protection from storm energetics. However, in single events retreat can be 3 – 4 times this long-term average. Individual storms deliver short term shocks to both the cliff and the beach system which can have serious socio-economic consequences, particularly significant in areas of critical coastal infrastructure. In this paper we look at two such recent events, the 5 December 2013 North Sea storm surge and the February – March 2018 “beast from the east” and “mini beast”. Each of these events left a large shoreline footprint, but each arose from different underpinning meteorological scenarios. Lessons can be learnt for future management planning.","PeriodicalId":254775,"journal":{"name":"Coastal Sediments 2019","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131300974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These type of datasets have the ability to provide critical information about changing beach morphodynamics in both the two and three-dimensional space. A regional experiment was established for the open ocean beaches of the Gold Coast, Australia. Two years of high spatial frequency survey at five sites within the Gold Coast embayment are presented here. This paper details the usefulness of the unique dataset and its ability to further inform previously poorly understood coastal morphodynamic questions, such as bar migration and spatial variability in beach state energy with respect to wave direction. By comparing the spatial variability in beach morphology between the survey sites, under two different wave directions, it is shown that the wave direction and attenuation play an important a role in shaping bar morphology along the coast.","PeriodicalId":254775,"journal":{"name":"Coastal Sediments 2019","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123616948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This enhances sediment transport and affects morphology, impacting navigation and aquatic vegetation. To better understand and predict these impacts, a numerical model corresponding to a 20 km long section of Currituck Sound, a narrow back-barrier estuary in North Carolina, was implemented with a 25 m resolution using Delft3D-SWAN for two 2016 tropical cyclones. Model results compare well with observations from instrumented platforms for both waves and water levels, and the simulated bed shear stress qualitatively matched observed trends in turbidity with considerable spatiotemporal variation. Satellite observations of red and infrared reflectance indicate considerable differences in total suspended matter between the two storms despite similar peak wind speeds. These preliminary results indicate detailed in situ observations and high resolution coupled numerical models can be used to quantify estuarine sediment transport during cyclonic storms.","PeriodicalId":254775,"journal":{"name":"Coastal Sediments 2019","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123683096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Globally, many coastal barriers are experiencing climatically altered environmental forcing coupled with increasing anthropogenic pressures. This paper undertakes high resolution shoreline change analysis to reveal how Blakeney Point, a mixed sandy-gravel barrier located on the UK’s East Coast, has evolved over centennial, decadal and event timescales. We seek to establish the implications of barrier evolution, under contrasting management regimes, for present erosion and flooding hazards. Interrogating a series of alternative shoreline proxies reveals a series of interdependent behaviors. Over the 130-year period of study, Blakeney Point is shown to be rolling landward at a mean rate of 0.60 m a-1. Assuming continued landward retreat over the coming decades, future flood-generating storm events will encounter more landward shoreline positions than today. Superimposed on this trend, we observe the presence of alongshore migrating erosional hotspots which give rise to unpredictable morphologies at any given location on the spit. Finally, we find that instances of barrier setback are driven by individual storm events, which makes barrier retreat both highly variable and discontinuous in time and space. This is illustrated by the presence of overwash, particularly along stretches of the barrier that have experienced a recent shift in management regime towards a non-interventionist approach.","PeriodicalId":254775,"journal":{"name":"Coastal Sediments 2019","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127542445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
