• Coastal Flood Boundaries - additional help and further information
• Where can I access the Coastal Flood Boundaries data and guidance documents?
• How is sea level rise accounted for in the CFB?
• I am concerned about the large differences in values in some locations and the effects on my project.
• Levels have fallen in my area of interest since the previous CFB update. How can this be when sea levels are known to be rising?
• What has changed in CFB 2018?
• I’ve been given MHWS and HAT predicted tide levels by another source. They don’t match up to those in the CFB. Which should I use?
• How are levels within ‘Inland Extensions’ or ‘estuaries’ derived?
• How should I use CFB levels in estuaries and tidal rivers?
• What are the key outputs of CFB 2018?
• What has been done to update the CFB in 2018?
• Why are regular updates, and therefore likely change in the estimates, necessary?
• How often is the CFB dataset updated?
• How can I generate my base tide curves?
• Are waves included in the CFB?
• What information is included in the extreme sea levels shapefiles?
• What is the accuracy of the CFB extreme sea levels?
• What is the vertical datum of the CFB levels?
• What is the base year for CFB levels?
• Which extreme sea level probabilities are included and what is meant by Annual Exceedance Probability?
• How does the CFB inform us about flood risk around the UK coast?
• Who should use this data?
• What are the Coastal Flood Boundaries?
