Location of BeachX. Inset wave rose shows the location and distribution of offshore waves from ERA5. b The detailed map of BeachX (Curl Curl Beach, New South Wales, Australia). The color gradient at the seaside indicates bathymetry. Yellow lines represent transects. Red dots show the location of nearshore waves.

Six example sites around Oʻahu with forecasted vegetation line positions for the month of July, under 0.3–1.2 m (1 ft (black)—4 ft (yellow)) of SLR. Locations are labeled by number and common beach name, and oriented with North pointing upwards in every photo except for Kūʻau. Inset of Oʻahu has labels of approximate locations of the example sites.

Map of study area: China Camp State Park and the adjacent shallows of San Pablo Bay. Black and gray bathymetry lines indicate the location of mean higher high water (MHHW) and mean lower low water (MLLW), respectively. Elevations in meters of those tidal datums are referenced to the North American Vertical Datum of 1988

Map of the North American West Coast, the monitored coastline is shown in light yellow. Dashed boxes delineate the different subregions of the study area. Pie charts show the regional distribution of advancing/retreating waterline trends during 2000–2022 derived from the dataset presented in this study.
