Hydrology
FEH Updates
This week saw the release of the new Flood Estimation Handbook (FEH) 2025 methodology, data and guidance.
All new hydrological analyses undertaken from now on should make use of this new methodology; any projects that are currently in progress fall within a transition timeframe, which differs between regulators. We’ll be speaking to our clients to ensure that they understand how this could impact their projects. Full details are available on the UK Centre for Ecology and Hydrology website here.
