Description: Anticipated positions of Mean High Water Springs per decade, based on a High Emissions Scenario sea level rise projection (RCP8.5, 95th percentile) and 'do nothing' coastal management approach. Shoreline retreat is limited by underlying physical susceptibility model (the UPSM of Fitton et al., 2017) and up to 25m of erosion is premitted at known artificial coastal defences. Further explanation available within Technical Summary WS2, via www.DynamicCoast.com/reports.
Name: Transects for High Emissions Pathway Sea Level Rise
Display Field: SubCell
Type: Feature Layer
Geometry Type: esriGeometryPolyline
Description: Transects spaced at 10m intervals along wave-dominated erodable shorelines as defined by Dynamic Coast. The transects display key information which inform coastal change calculations (incl. date and source of tide lines, anticipated relative sea level rise) alongside key results (incl. erosion amount and rate per decade). Further explanation available within Technical Summary WS2, via www.DynamicCoast.com/reports.
Description: Mean High Water Springs tide line extracted from high resolution Digital Elevation Models, typically derived from airborne LiDAR datasets. Date of survey varies spatially, query line for source information. Data sourced from https://remotesensingdata.gov.scot/ and partner data (NatureScot, Historic Environment Scotland etc).
Description: Mean High Water Spring, digitised from OS National Grid 1:10,560/1:10,000 sheets. Epoch 1956 to 1995. Extent: Soft or Erodible shorelines. This data was digitised as part of the National Coastal Change Assessment, see www.dynamiccoast.com for more info. Updated as part of the second phase of Dynamic Coast research (2021).
Description: High Water Mark of Ordinary Spring Tide. Digitised from the OS 2nd Edition. Scale 6 inch map (1:10,560) county series. Epoch 1890 to 1959. The 'soft' or erodible shoreline has been mapped, not the whole coastline. For more information see www.dynamiccoast.com Updated as part of the second phase of Dynamic Coast research (2021).
Name: FutureCoast Erosion Polygons (2050) for High Emissions Scenario SLR
Display Field: Layer
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: Anticipated erosional areas, between the current 2020 and anticipated 2050 Mean High Water Spring tide lines, based on a High Emissions Scenario sea level rise projection (RCP8.5, 95 percentile) and 'do nothing' coastal management approach. Shoreline retreat is limited by underlying physical susceptibility model (the UPSM of Fitton et al., 2017) and up to 25m of erosion is premitted at known artificial coastal defences. Dataset includes Erosion Area (areas seawards of the 2050 projected position of Mean High Water Springs), Erosion Influence (a 10m landward buffer of the projected position of 2050 MHWS) and Erosion Vicinity (a further 50m landward buffer on Erosion Influence). This data contains the intersect values for society's assets (lengths of roads (km), areas of designates sites (ha)).

Display Field: Layer
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: Anticipated erosional areas, between the 2020 and anticipated 2100 Mean High Water Spring tide lines, based on a High Emissions Scenario sea level rise projection (RCP8.5, 95 percentile) and 'do nothing' coastal management approach. Shoreline retreat is limited by underlying physical susceptibility model (the UPSM of Fitton et al., 2017) and up to 25m of erosion is premitted at known artificial coastal defences. Dataset includes Erosion Area (areas seawards of the 2050 projected position of Mean High Water Springs), Erosion Influence (a 10m landward buffer of the projected position of 2050 MHWS) and Erosion Vicinity (a further 50m landward buffer on Erosion Influence). This data contains the intersect values for society's assets (lengths of roads (km), areas of designates sites (ha)).

Description: Artificial sea front defences were digitised around the coast of Scotland, for use in informing on pre-existing coastal protection and in limiting the amount of erosion predicted as part of the Dynamic Coast FutureCoast shorelines.
