The National River Flow Archive (NRFA) has released an update of the WINFAP-FEH data files for use in flood estimation.
It includes a revised annual maxima (AMAX) and peaks over threshold (POT) time-series data at gauging stations across England, Wales and Northern Ireland up to September 2014 (bit.ly/1ZJh22h).
The NRFA’s peak flow data service provides flood data from 959 river flow gauging stations around the UK.
The updated files include data from five new stations in the West Midlands, Wessex and north-west England regions. The database is calculated to provide net economic benefits of almost £5.4 million per year in terms of costs saved by environmental consultants and regulators.
