What is the FEH?

The Flood Estimation Handbook (FEH) offers guidance on rainfall and river flood frequency estimation in the UK. Flood frequency estimates are required for the planning and assessment of flood defences, and the design of other structures such as bridges, culverts, and reservoir spillways.

  • Flood risk analysis
  • New development planning
  • Rarity assessment of notable rainfalls or floods
