This was examined using a 2D XBeach short wave-averaged (surfbeat, XB-SB) and a wave-resolving (non-hydrostatic, XB-NH) model of Roi-Namur Island on Kwajalein Atoll in the Republic of Marshall Islands. Results show that explicitly modelling the sea-swell component (using XB-NH) provides a better approximation of the observed runup than XB-SB (which only models the time-variation of the sea-swell wave height), despite good model performance of both models on reef flat water levels and wave heights. However, both models under-predict runup peaks. The difference between XB-SB and XB-NH increases for more extreme wave events and higher sea levels, as XB-NH resolves individual waves and therefore captures SS-wave motions in runup. However, for even larger forcing conditions with offshore wave heights of 6 m, the island is flooded in both XB-SB and XB-NH computations, regardless of the sea-swell wave energy contribution. In such cases, XB-SB would be adequate to model flooding depths and extents on the island while requiring 4-5 times less computational effort.\nThese input files accompany the modeling for following publication: Quataert, E., Storlazzi, C., van Dongeren, A., and McCall, R., 2020, The importance of explicitly modeling sea-swell waves for runup on reef-lined coasts: Coastal Engineering, https://doi.org/10.1016/j.coastaleng.2020.103704", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9XUI9Y1", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.5e59692ee4b01d50924c5370.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5e59692ee4b01d50924c5370", "keyword": ["CMHRP", "Coastal and Marine Hazards and Resources Program", "Kwajalein Atoll", "PCMSC", "Pacific Coastal and Marine Science Center", "Republic of the Marshall Islands", "Roi-Namur", "U.S. Geological Survey", "USGS", "USGS:5e59692ee4b01d50924c5370", "coastal processes", "coral reefs", "flooding", "geoscientificInformation", "hazards", "numerical modeling", "oceans", "reef", "water column features", "water level", "waves"], "modified": "2021-10-13T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "167.461, 9.388, 167.490, 9.406", "theme": ["geospatial"], "title": "Model parameter input files to compare wave-averaged versus wave-resolving XBeach coastal flooding models for coral reef-lined coasts"}
