Coastal Design Sea Levels - Coastal Flood Boundary Surge Shapes (2018)
This metadata record is for AfA product AfA 010. Coastal Flood Boundary Surge Shapes is part of Coastal Design/Extreme Sea Levels, a GIS dataset and supporting information providing design / extreme sea level and typical surge information around the coastline of the UK, including England, Wales, Scotland, Northern Ireland, Isle of Man and Jersey. The information is relevant under present day (year 2018) conditions and does not account for future changes due to climate change, such as sea level r

Useful for
- Use cases llm-inferred
- Coastal flood modelling: surge shape extents to build design time series water level boundary conditions · Flood risk assessment: coastal design water levels for sites on the UK coast · Coastal scheme design: surge profile inputs for design water levels · Strategic planning: screening coastal surge extents at a regional scale
- Audience llm-inferred
- flood modellers · flood risk consultants · coastal engineers · civils engineers · strategic planners · GIS analysts
Limitations
- Constraints llm-inferred
- Relevant to present-day (2018) conditions only; does not account for climate change or sea level rise · Specialist dataset: surge profile data sits in a separate Excel spreadsheet · Update frequency is irregular · Publisher is Environment Agency but the licence/access constraint names Copyright Associated British Ports 2010-2014; confirm reuse terms before use · Shows surge profile extents, not flood extents or depths by itself
