- How should I use Coastal Flood Boundaries levels in estuaries and tidal rivers?
- I am concerned about the large differences in values in some locations and the effects on my project
- I’ve been given mean high water springs (MHWS) and highest astronomical tide (HAT) predicted Tide Levels by another source. They don’t match up to those in the Coastal Flood Boundaries. Which should I use?
- Levels have fallen in my area of interest since the previous Coastal Flood Boundaries update. How can this be when sea levels are known to be rising?

What are the key outputs of Coastal Flood Boundaries 2018?
Created: 03 October 2019 Updated: 03 October 2019
The following were updated or added to the dataset in 2018:
ESLs of annual exceedance probability ranging from 1-year to 10,000-year return period
highest astronomical tide and mean high water spring tide conditions for some locations
ESLs for the full study area coastline at a spacing of about 2km along the open coast or less in estuaries and harbours (enabling rapid selection of appropriate levels without any need for further interpolation)
advice on generating appropriate total storm tide curves for use with the extreme sea levels
extension of the dataset in several key estuaries
The following were not updated in 2018:
extreme swell wave conditions were supplied for CFB 2011 but were not updated for CFB 2018
