The BGS coastal vulnerability dataset combines multi-hazards within the coastal zone of England and Wales. It represents the natural geological coastline (around the mainland of England and Wales only) 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 This will be of particular value in areas where coastal defences are no longer maintained.

The dataset currently contains the following layers:

  • backshore: erosion susceptibility of the cliff
  • foreshore: presence of beaches, tidal flats, salt marshes and wave-cut platforms
  • clifftop height: sampled at 50 m intervals
  • inundation: coastal, fluvial and groundwater flooding

The coastal vulnerability dataset has been developed with a number of stakeholders that have an interest in the coast. It can be used alongside existing shoreline management plans and can be used to interpret potential interdependencies in terms of erosion, flooding, habitat and other vulnerabilities.
