    What are the Coastal Flood Boundaries?


    Successful management of coastal flood risk and coastal protection work requires the best available information on extreme sea-levels (ESLs) and other important drivers of coastal flood and erosion risk. The Coastal Flood Boundary Conditions for UK Mainland and Islands (CFB), first published in 2011, supports this work with a robust and consistently derived evidence base. The CFB dataset includes:

    • a continuous and spatially consistent set of ESLs around the coasts of England, Wales, Scotland, Northern Ireland, Isle of Man and Jersey
    • a means of generating appropriate total storm tide curves for use with the extreme sea levels
    • best practice guidance on how to use these new datasets

    This 2018 CFB update was carried out for the UK Coastal Flood Forecasting partnership, which includes the Environment Agency, Scottish Environment Protection Agency, Natural Resources Wales and the Department for Infrastructure Northern Ireland. The work was conducted by a project team including JBA Consulting, Professor Jonathan Tawn of Lancaster University and the National Oceanography Centre. The project also included extensive consultation with UK practitioners and subject matter experts.
