WINFAP-FEH Files Version History

Back to WINFAP-FEH Files

The first full version of the WINFAP-FEH data files (version 1.1) were released on 1 August 2005 under the HiFlows-UK Project. The HiFlows-UK dataset superseded the FEH Flood Peak Dataset provided with Volume 3 of the Flood Estimation Handbook (Institute of Hydrology, 1999). Since 2004 a number of subsequent updates to the data files have been released. A more detailed history of the national peak flow dataset can be found below.

For the most recent list of major changes (e.g. to flow data and station suitability) users should refer to the release note for Version 4.
