Here, we introduce an input-reduction framework for wave-dominated coastal settings. Our framework comprises 4 steps, viz. (1) the selection of the duration of the original (full) time series of wave forcing, (2) the selection of the representative wave conditions, (3) the sequencing of these conditions, and (4) the time span after which the sequence is repeated. In step (2), the chronology of the original series is retained, while that is no longer the case in steps (3) and (4). We apply the framework to two different sites (Noordwijk, Netherlands and Hasaki, Japan) with multiple nearshore sandbars but contrasting long-term offshore-directed behavior: at Noordwijk the offshore migration is gradual and not coupled to individual storms, while at Hasaki the offshore migration is more episodic, and wave chronology appears to control long-term evolution. The performance of the model with reduced wave climates is referenced to a simulation with the actual (full) wave-forcing series. We demonstrate that input reduction can dramatically affect long-term predictions, even to such an extent that the main characteristics of the offshore bar cycle are no longer reproduced. This was particularly the case at Hasaki, where all synthetic series that no longer capture the initial chronology (steps 3 and 4) lead to rather unrealistic long-term simulations. At Noordwijk, synthetic series can result in realistic behavior, provided that the time span after which the sequence is repeated is not too large; the reduction of this time span has the same positive effect on the simulation as increasing the number of selected conditions in step 2. We further demonstrate that, although storms result in the largest morphological change, conditions with low to intermediate wave energy must be retained to obtain realistic long-term sandbar behavior. Our input-reduction framework must be applied in an iterative fashion as to obtain a reduced wave climate that simulates long-term sandbar sufficiently accurately within an acceptable computation time. Given its potentially huge impact on the actual simulation, we believe it is imperative to consider input reduction as an intrinsic part of model set-up, calibration and validation.", "publicationTitle": "Coastal Engineering", "publisher": "", "place": "", "date": "July 1, 2013", "volume": "77", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "57-70", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Coastal Engineering", "DOI": "10.1016/j.coastaleng.2013.02.001", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0378383913000276", "accessDate": "2018-11-26T13:35:51Z", "PMID": "", "PMCID": "", "ISSN": "0378-3839", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Cyclic bar behavior", "type": 1 }, { "tag": "Input filtering", "type": 1 }, { "tag": "Input reduction", "type": 1 }, { "tag": "Morphodynamic modeling", "type": 1 }, { "tag": "Process based modeling", "type": 1 }, { "tag": "Unibest-TC", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2018-11-26T13:35:51Z", "dateModified": "2018-11-26T13:35:51Z" } }, { "key": "92YV267A", "version": 8619, "library": { "type": "group", "id": 21089, "name": "Barts Digital Library", "links": { "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21089/items/92YV267A", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library/items/92YV267A", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/21089/items/NDRI8V6A", "type": "application/json" } }, "meta": { "createdByUser": { "id": 284290, "username": "BGrasmeijer", "name": "Bart Grasmeijer", "links": { "alternate": { "href": "https://www.zotero.org/bgrasmeijer", "type": "text/html" } } } }, "data": { "key": "92YV267A", "version": 8619, "parentItem": "NDRI8V6A", "itemType": "attachment", "linkMode": "imported_url", "title": "Snapshot", "accessDate": "2018-11-20T09:08:23Z", "url": "https://www.mdpi.com/2077-1312/6/4/126", "note": "", "contentType": "text/html", "charset": "utf-8", "filename": "126.html", "md5": "90fc705d69340f9b1772d6a965a5ec76", "mtime": 1542704903230, "tags": [], "relations": {}, "dateAdded": "2018-11-20T09:08:23Z", "dateModified": "2018-11-20T09:08:23Z" } }, { "key": "PSDAY5NA", "version": 8620, "library": { "type": "group", "id": 21089, "name": "Barts Digital Library", "links": { "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21089/items/PSDAY5NA", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library/items/PSDAY5NA", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/21089/items/NDRI8V6A", "type": "application/json" } }, "meta": { "createdByUser": { "id": 284290, "username": "BGrasmeijer", "name": "Bart Grasmeijer", "links": { "alternate": { "href": "https://www.zotero.org/bgrasmeijer", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "PSDAY5NA", "version": 8620, "parentItem": "NDRI8V6A", "itemType": "attachment", "linkMode": "imported_url", "title": "Full Text PDF", "accessDate": "2018-11-20T09:08:19Z", "url": "https://www.mdpi.com/2077-1312/6/4/126/pdf", "note": "", "contentType": "application/pdf", "charset": "", "filename": "Donker et al. -

While our knowledge into the mechanisms behind foredune erosion have reached considerable maturity, this is not the case for foredune growth. High resolution spatio-temporal data sets of beach and foredune topography, which are needed to increase our understanding of mechanisms behind aeolian transport in coastal environments and to develop predictive dune-accretion models, are scarce. Here we aim to illustrate that repeated Mobile Laser Scanning (MLS) surveys provide an accurate and robust method to study detailed changes in dune volume on the timescales of months to years. An MLS system attached to an inertial navigation system with RTK-GPS (INS-GPS) was used to carry out 13 surveys along a 3.5-km Dutch beach over a 2.5-year period. The height observations were post-processed and averaged into 1 × 1 m Digital Elevation Models (DEMs). Comparison with airborne LiDAR and RTK-GPS data revealed that the obtained DEMs were accurate and robust up to a height of 15 m in the foredune above which dense vegetation hampers the MLS to see the sand surface. Estimates of dune volume change of the lower 13 m of the foredune have an uncertainty of about 0.25 m 3 /m. Time series of dune volume change show that at our study site the foredune accretes throughout the year at similar rates (10 m 3 /m/year), while marine erosion is obviously confined to storm surges.

This study utilizes detailed observations (immediately pre, during and post-storm topography, waves and water levels) collected over a 6-day period at the 3.6 km long Narrabeen-Collaroy beach in south-east Australia, to identify and explore drivers of the highly variable alongshore dune erosion caused by an East Coast Low storm in June 2011. Key characteristics of the immediately pre-storm subaerial morphology obtained by airborne Lidar (beach slope, dune toe elevation, dune height) varied considerably alongshore. Daily airborne Lidar surveys conducted at low tide indicated considerable temporal variability in the evolution of the subaerial beach profile. Despite considerable alongshore variability in the magnitude of modelled inshore wave heights during the storm, it was instead observed that the predominant determinant of maximum dune erosion was the pre-storm dune toe elevation. A simple dune impact model forced with local alongshore-variable inshore wave modelling was found to successfully predict up to 85% of the observed alongshore variability in dune erosion at this site, with this erosion tidally modulated over the 6 days to time periods when the waves were directly impacting the dune. Importantly, alongshore variation in wave height is shown to account for just 10% of the alongshore variability in dune erosion during this storm. These results reconfirm that knowledge of the pre-storm subaerial morphology, in particular the elevation of the dune toe with respect to time-varying water levels during a storm, is a key driver of alongshore variability in the erosion response along dune-backed sandy coastlines.", "publicationTitle": "Coastal Engineering", "publisher": "", "place": "", "date": "January 1, 2018", "volume": "131", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "31-41", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Coastal Engineering", "DOI": "10.1016/j.coastaleng.2017.10.011", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0378383916304070", "accessDate": "2018-10-05T13:51:48Z", "PMID": "", "PMCID": "", "ISSN": "0378-3839", "archive": "", "archiveLocation": "", "shortTitle": "Drivers of alongshore variable dune erosion during a storm event", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Collision regime", "type": 1 }, { "tag": "Dune erosion", "type": 1 }, { "tag": "Dune impact model", "type": 1 }, { "tag": "Narrabeen-Collaroy", "type": 1 }, { "tag": "Storm Impact Scale", "type": 1 }, { "tag": "Swash regime", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2018-10-05T13:51:48Z", "dateModified": "2018-10-05T13:51:48Z" } }, { "key": "AKTGZ9YI", "version": 8610, "library": { "type": "group", "id": 21089, "name": "Barts Digital Library", "links": { "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21089/items/AKTGZ9YI", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library/items/AKTGZ9YI", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/21089/items/SBZQAKWQ", "type": "application/json" } }, "meta": { "createdByUser": { "id": 284290, "username": "BGrasmeijer", "name": "Bart Grasmeijer", "links": { "alternate": { "href": "https://www.zotero.org/bgrasmeijer", "type": "text/html" } } } }, "data": { "key": "AKTGZ9YI", "version": 8610, "parentItem": "SBZQAKWQ", "itemType": "attachment", "linkMode": "imported_url", "title": "ScienceDirect Snapshot", "accessDate": "2018-10-05T13:48:10Z", "url": "https://www.sciencedirect.com/science/article/pii/S0378383913001579?dgcid=raven_sd_recommender_email", "note": "", "contentType": "text/html", "charset": "utf-8", "filename": "S0378383913001579.html", "md5": "a025755a2fb99510e2977e0f94446c92", "mtime": 1538747290468, "tags": [], "relations": {}, "dateAdded": "2018-10-05T13:48:10Z", "dateModified": "2018-10-05T13:48:10Z" } }, { "key": "SBZQAKWQ", "version": 8609, "library": { "type": "group", "id": 21089, "name": "Barts Digital Library", "links": { "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21089/items/SBZQAKWQ", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library/items/SBZQAKWQ", "type": "text/html" } }, "meta": { "createdByUser": { "id": 284290, "username": "BGrasmeijer", "name": "Bart Grasmeijer", "links": { "alternate": { "href": "https://www.zotero.org/bgrasmeijer", "type": "text/html" } } }, "creatorSummary": "Splinter et al.", "parsedDate": "2014-01-01", "numChildren": 1 }, "data": { "key": "SBZQAKWQ", "version": 8609, "itemType": "journalArticle", "title": "A relationship to describe the cumulative impact of storm clusters on beach erosion", "creators": [ { "creatorType": "author", "firstName": "Kristen D.", "lastName": "Splinter" }, { "creatorType": "author", "firstName": "James T.", "lastName": "Carley" }, { "creatorType": "author", "firstName": "Aliasghar", "lastName": "Golshani" }, { "creatorType": "author", "firstName": "Rodger", "lastName": "Tomlinson" } ], "abstractNote": "Estimation of erosion volumes for adequate dry beach buffer zones is commonly estimated on the basis of a single extreme event, such as the 1 in 100year storm. However, the cumulative impact of several smaller, closely spaced storms can lead to equal, if not more, dry beach loss, but this is often not quantified. Here we use a calibrated model for dune erosion, XBeach, to hindcast the cumulative erosion impact of a series of historical storms that impacted the Gold Coast, Queensland region in 1967. Over a 6-month period, four named cyclones (Dinah, Barbara, Elaine, and Glenda) and three East Coast Lows caused a cumulative erosion volume greater than the predicted 1 in 100year event. Results presented here show that XBeach was capable of reproducing the measured dry beach erosion volume to within 21% and shoreline retreat to within 10%. The storms were then run in 17 different sequences to determine if sequencing influenced final modeled erosion volumes. It is shown that storm sequencing did not significantly affect the total eroded volumes. However, individual storm volumes were influenced by the antecedent state of the beach (i.e. prior cumulative erosion). Power-law relationships between cumulative energy density (∑E) and eroded volume (∆V) as well as cumulative wave power ((∑P)) and eroded volume (∆V) both explained more than 94% of the modeled dry beach erosion for the 1967 storm sequences. When the relationship was compared with observed and modeled erosion volumes for similar beaches but different storm forcing, the inclusion of pre-storm beach swash slope (βswash) in the parameterization was found to increase the applicability of the power-law relationship over a broader range of conditions.", "publicationTitle": "Coastal Engineering", "publisher": "", "place": "", "date": "January 1, 2014", "volume": "83", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "49-55", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Coastal Engineering", "DOI": "10.1016/j.coastaleng.2013.10.001", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0378383913001579", "accessDate": "2018-10-05T13:47:36Z", "PMID": "", "PMCID": "", "ISSN": "0378-3839", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Beach erosion", "type": 1 }, { "tag": "Dune erosion", "type": 1 }, { "tag": "Extreme storms", "type": 1 }, { "tag": "Gold Coast", "type": 1 }, { "tag": "Storm clusters", "type": 1 }, { "tag": "Storm sequencing", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2018-10-05T13:47:36Z", "dateModified": "2018-10-05T13:47:36Z" } }, { "key": "5L23FED2", "version": 8608, "library": { "type": "group", "id": 21089, "name": "Barts Digital Library", "links": { "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21089/items/5L23FED2", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library/items/5L23FED2", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/21089/items/GCN2E8D4", "type": "application/json" } }, "meta": { "createdByUser": { "id": 284290, "username": "BGrasmeijer", "name": "Bart Grasmeijer", "links": { "alternate": { "href": "https://www.zotero.org/bgrasmeijer", "type": "text/html" } } } }, "data": { "key": "5L23FED2", "version": 8608, "parentItem": "GCN2E8D4", "itemType": "attachment", "linkMode": "imported_url", "title": "Snapshot", "accessDate": "2018-08-16T07:49:36Z", "url": "http://link.springer.com/article/10.1007/s10236-018-1204-2", "note": "", "contentType": "text/html", "charset": "utf-8", "filename": "s10236-018-1204-2.html", "md5": "07bf1af13c4ac2c1a3b8172bd1171892", "mtime": 1534405776731, "tags": [], "relations": {}, "dateAdded": "2018-08-16T07:49:36Z", "dateModified": "2018-08-16T07:49:37Z" } }, { "key": "63JAGMPW", "version": 8607, "library": { "type": "group", "id": 21089, "name": "Barts Digital Library", "links": { "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21089/items/63JAGMPW", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library/items/63JAGMPW", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/21089/items/GCN2E8D4", "type": "application/json" } }, "meta": { "createdByUser": { "id": 284290, "username": "BGrasmeijer", "name": "Bart Grasmeijer", "links": { "alternate": { "href": "https://www.zotero.org/bgrasmeijer", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "63JAGMPW", "version": 8607, "parentItem": "GCN2E8D4", "itemType": "attachment", "linkMode": "imported_url", "title": "Full Text PDF", "accessDate": "2018-08-16T07:49:33Z", "url": "http://link.springer.com/content/pdf/10.1007%2Fs10236-018-1204-2.pdf", "note": "", "contentType": "application/pdf", "charset": "", "filename": "Rijn et al. -

Deepening often leads to tidal amplification, salinity intrusion, and increasing sand and mud import. These effects can be modelled and studied by using detailed 3D models. Reliable simplified models for a first quick evaluation are however lacking. This paper presents a simplified model for sand transport in prismatic and converging tidal channels. The simplified model is a local model neglecting horizontal sand transport gradients. The latter can be included by coupling (as post-processing) the simplified model to a 2DH or 3D flow model. Basic sand transport processes in stratified tidal flow are studied based on the typical example of the tidal Rotterdam Waterway in The Netherlands. The objective is to gain quantitative understanding of the effects of channel deepening on tidal penetration, salinity intrusion, tidal asymmetry, residual density-driven flow, and the net tide-integrated sand transport. We firstly study the most relevant tidal parameters at the mouth and along the channel with simple linear tidal models and numerical 2DH and 3D tidal models. We then present a simplified model describing the transport of sand (TSAND) in tidal channels. The TSAND model can be used to compute the variation of the depth-integrated suspended sand transport and total sand transport (incl. bed-load transport) over the tidal cycle. The model can either be used in stand-alone mode or with computed near-bed velocities from a 3D hydrodynamic model as input data.", "publicationTitle": "Ocean Dynamics", "publisher": "", "place": "", "date": "2018/08/15", "volume": "", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "1-23", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Ocean Dynamics", "DOI": "10.1007/s10236-018-1204-2", "citationKey": "", "url": "http://link.springer.com/article/10.1007/s10236-018-1204-2", "accessDate": "2018-08-16T07:49:32Z", "PMID": "", "PMCID": "", "ISSN": "1616-7341, 1616-7228", "archive": "", "archiveLocation": "", "shortTitle": "Effect of channel deepening on tidal flow and sediment transport", "language": "en", "libraryCatalog": "link-springer-com.proxy.library.uu.nl", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2018-08-16T07:49:32Z", "dateModified": "2018-08-16T07:49:32Z" } }, { "key": "8PIXXNMH", "version": 8604, "library": { "type": "group", "id": 21089, "name": "Barts Digital Library", "links": { "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21089/items/8PIXXNMH", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library/items/8PIXXNMH", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/21089/items/73F4RMTP", "type": "application/json" } }, "meta": { "createdByUser": { "id": 284290, "username": "BGrasmeijer", "name": "Bart Grasmeijer", "links": { "alternate": { "href": "https://www.zotero.org/bgrasmeijer", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "8PIXXNMH", "version": 8604, "parentItem": "73F4RMTP", "itemType": "attachment", "linkMode": "imported_url", "title": "ScienceDirect Full Text PDF", "accessDate": "2018-08-15T11:37:37Z", "url": "https://ac.els-cdn.com/S0025322717303663/1-s2.0-S0025322717303663-main.pdf?_tid=c215f1b7-25bc-487d-9320-71dab3a2607d&acdnat=1534333232_39183270758359038a2eaf6ecdf4715f", "note": "", "contentType": "application/pdf", "charset": "", "filename": "Nowacki and Ganju - 2018 - Storm impacts on hydrodynamics and suspended-sedim.pdf", "md5": "d71169207b83f45724e424408af942a6", "mtime": 1534333057572, "tags": [], "relations": {}, "dateAdded": "2018-08-15T11:37:37Z", "dateModified": "2018-08-15T11:37:37Z" } }, { "key": "8TWI39RK", "version": 8603, "library": { "type": "group", "id": 21089, "name": "Barts Digital Library", "links": { "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21089/items/8TWI39RK", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library/items/8TWI39RK", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/21089/items/73F4RMTP", "type": "application/json" } }, "meta": { "createdByUser": { "id": 284290, "username": "BGrasmeijer", "name": "Bart Grasmeijer", "links": { "alternate": { "href": "https://www.zotero.org/bgrasmeijer", "type": "text/html" } } } }, "data": { "key": "8TWI39RK", "version": 8603, "parentItem": "73F4RMTP", "itemType": "attachment", "linkMode": "imported_url", "title": "ScienceDirect Snapshot", "accessDate": "2018-08-15T11:37:36Z", "url": "https://www.sciencedirect.com/science/article/pii/S0025322717303663?via%3Dihub", "note": "", "contentType": "text/html", "charset": "utf-8", "filename": "S0025322717303663.html", "md5": "fce562b6c5aa2bee60bb1bffb4b98ebb", "mtime": 1534333056805, "tags": [], "relations": {}, "dateAdded": "2018-08-15T11:37:36Z", "dateModified": "2018-08-15T11:37:36Z" } }, { "key": "73F4RMTP", "version": 8602, "library": { "type": "group", "id": 21089, "name": "Barts Digital Library", "links": { "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21089/items/73F4RMTP", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library/items/73F4RMTP", "type": "text/html" } }, "meta": { "createdByUser": { "id": 284290, "username": "BGrasmeijer", "name": "Bart Grasmeijer", "links": { "alternate": { "href": "https://www.zotero.org/bgrasmeijer", "type": "text/html" } } }, "creatorSummary": "Nowacki and Ganju", "parsedDate": "2018-10-01", "numChildren": 2 }, "data": { "key": "73F4RMTP", "version": 8602, "itemType": "journalArticle", "title": "Storm impacts on hydrodynamics and suspended-sediment fluxes in a microtidal back-barrier estuary", "creators": [ { "creatorType": "author", "firstName": "D.

To that end, flow velocity, wave characteristics, and suspended-sediment concentration (SSC) were measured for 11 months at eight locations in Chincoteague Bay, MD/VA, USA, a shallow back-barrier estuary. Daily breezes and episodic storms generated sediment-resuspending waves and modified the flow velocity at all sites, which occupied channel, shoal, and sheltered-bay environments with different bed-sediment characteristics. Despite comparable SSC during calm periods, SSC at the channel locations was considerably greater than at the shoal sites during windy periods because of relatively more erodible bed sediment in the channels. Sediment fluxes were strongly wind modulated: within the bay's main channel, depth-integrated unit-width sediment flux increased nonlinearly with increasing wind speed. When averaged over all sites, about 35% of the flux occurred during windy periods (wind speed greater than 6 m s−1), which represented just 15% of the deployment time. At channel sites, the net water and sediment fluxes were opposite to the direction of the wind forcing, while at shoal sites, the fluxes generally were aligned with the wind, implying complex channel–shoal dynamics. Yearly sediment fluxes exceed previous estimates of sediment delivery to the entirety of Chincoteague Bay. These observations illustrate the dynamic sedimentary processes occurring within microtidal back-barrier lagoons and highlight the importance of storm events in the hydrodynamics and overall sediment budgets of these systems.", "publicationTitle": "Marine Geology", "publisher": "", "place": "", "date": "October 1, 2018", "volume": "404", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "1-14", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Marine Geology", "DOI": "10.1016/j.margeo.2018.06.016", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0025322717303663", "accessDate": "2018-08-15T11:37:32Z", "PMID": "", "PMCID": "", "ISSN": "0025-3227", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2018-08-15T11:37:33Z", "dateModified": "2018-08-15T11:37:33Z" } }, { "key": "PSZ3TZ8R", "version": 8600, "library": { "type": "group", "id": 21089, "name": "Barts Digital Library", "links": { "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21089/items/PSZ3TZ8R", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/barts_digital_library/items/PSZ3TZ8R", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/21089/items/Y473F6J9", "type": "application/json" } }, "meta": { "createdByUser": { "id": 284290, "username": "BGrasmeijer", "name": "Bart Grasmeijer", "links": { "alternate": { "href": "https://www.zotero.org/bgrasmeijer", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "PSZ3TZ8R", "version": 8600, "parentItem": "Y473F6J9", "itemType": "attachment", "linkMode": "imported_url", "title": "ScienceDirect Full Text PDF", "accessDate": "2018-08-15T11:35:42Z", "url": "https://ac.els-cdn.com/S0025322718300343/1-s2.0-S0025322718300343-main.pdf?_tid=46b5e322-25d2-4213-8ec5-b7e46660f448&acdnat=1534333116_1b6f5e73518c1bc2302b0e769bc10abc", "note": "", "contentType": "application/pdf", "charset": "", "filename": "Athanasiou et al. -

To increase the number of sandbar observations available from bathymetric surveys, this study proposes and evaluates a method to manually extract the sandbar location using freely available satellite imagery for the case study of Anmok beach in South Korea. Validation of the satellite extracted sandbar locations against 9 in-situ measurements shows good agreement with errors well within the pixel resolution of the satellite imagery (i.e. 30 m for Landsat missions). The applicability of the method is constrained to locations where (1) the cross-shore crescentic length scales are larger than the image resolution, (2) frequent wave breaking and clouds are absent and (3) the water clarity is sufficient to enable the manual extraction of the sandbar crest line. Using the additional sandbar observations from the satellite imagery significantly increases the temporal extent and resolution of the dataset for Anmok beach. This allows the study of sandbar characteristics, dynamics and impacts of human interventions to an extent that would not have been possible without the satellite imagery. Within the study period 1990–2017 it is found that the sandbar maintains a persistent crescentic pattern that is only altered during prolonged and very intense storm conditions. The cumulative alongshore migration of the sandbars is investigated and found to be in the order of hundreds of meters over the 27 years study period. Comparing the sandbar characteristics prior and after the construction of Gangneung port shows that both the amplitudes and wavelengths of the sandbar crescents near the port have decreased after its construction.", "publicationTitle": "Marine Geology", "publisher": "", "place": "", "date": "November 1, 2018", "volume": "405", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "1-11", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Marine Geology", "DOI": "10.1016/j.margeo.2018.07.013", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0025322718300343", "accessDate": "2018-08-15T11:35:36Z", "PMID": "", "PMCID": "", "ISSN": "0025-3227", "archive": "", "archiveLocation": "", "shortTitle": "Analysing decadal-scale crescentic bar dynamics using satellite imagery", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Anmok beach", "type": 1 }, { "tag": "Crescentic sandbars", "type": 1 }, { "tag": "Human interventions", "type": 1 }, { "tag": "Sandbar dynamics", "type": 1 }, { "tag": "Satellite imagery", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2018-08-15T11:35:36Z", "dateModified": "2018-08-15T11:35:36Z" } } ]
