This is a specialist dataset which informs on work commenced around the coast ranging from coastal flood modelling, scheme design, strategic planning and flood risk assessments. \r\n\r\nThe dataset contains the following layer components: \r\n- Extreme Sea Level Values: Extreme sea levels for a range of return periods \r\n- Extreme Sea Level Confidence Level: Confidence intervals providing allowances for uncertainty \r\n- Estuary Boundaries: Inland estuarine boundaries of the extreme sea levels \r\n- Surge Shape Locations: Reference to surge shape appropriate for each Class A gauge site and where to apply it \r\n- Tide Gauge Locations: Location of gauging stations",
