The British Geological Survey (BGS) is developing a Coastal Vulnerability Index (CVI). This is a Geographic Information System (GIS)-based analysis for indicating multi-hazards and interdependencies within the coastal zone of England and Wales. Version 1 was released in August 2017.The mainland of England and Wales is surrounded by over 12 000 km of coastline. It is a very diverse coastline both in terms of geology and geomorphology, ranging from the high chalk cliffs of Sussex to the low-lying expanses of The Wash and Morecambe Bay. The winter storms of 2013-14 starkly demonstrated the vulnerability of the coastline of Wales and England to erosion and overtopping by waves and storm surges, but when responding to media enquiries it became clear that a national picture of the sections of coastline susceptible to erosion, based on geology, didn’t exist. The Coastal Vulnerability Index has been created to fill this knowledge gap.
The CVI will offer anyone with assets or an interest in the coastline around England and Wales access to easy-to use datasets linked to geohazard data. This will allow users to interpret potential interdependencies in terms of erosion, flooding (inundation), habitat and other vulnerabilities.Back to all speakers
