GeoCoast Premium provides a range of geological and geomorphological properties that influence coastal vulnerability. They are provided as attributed 50 m grid cells around the coastline of Great Britain. The data has been developed from BGS databases and datasets, regional expertise and additional analytics to compile the essential baseline geo-information necessary to feed into coastal vulnerability analyses and assessments for resilience and adaptation. GeoCoast Premium consists of: • coast grid dataset -Foreshore (type; properties; spatial area) -backshore (type; properties; spatial area) -coastal erosion susceptibility overview (vertical cliff layers; properties) -cliff profiling (slope angle; distance; cliff height) -potential inundation zones under climate change scenarios (future sea level rise forecast for 2050, 2080 and 2100) -coastal subsidence potential (satellite measurements and lithology type) • groundwater flooding and coastal flood dataset (combined hazards indicating exacerbated impact) • coastal erosion susceptibility dataset (a full lithology by lithology detailed attributes) The BGS GeoCoast dataset is a Geographic Information System (GIS)-based analysis for indicating multi-hazards and interdependencies within the coastal zone of Great Britain (not including Orkney and Shetland). GeoCoast represents the natural geological coastline (around the mainland of Great Britain) as if no coastal defences or made ground are present. This will be of particular value in areas where coastal defences are no longer maintained. GeoCoast will offer anyone with assets, or an interest in the coastline around Great Britain, access to easy-to-use datasets linked to geohazard data. This will allow users to interpret potential interdependencies in terms of erosion, flooding, habitat and other vulnerabilities.
