Welcome to the National River Flow Archive

The National River Flow Archive (NRFA) is the UK’s focal point for river flow data.

The NRFA collates, quality controls, and archives hydrometric data from gauging station networks across the UK including the extensive networks operated by the Environment Agency (England), Natural Resources Wales, the Scottish Environment Protection Agency and the Rivers Agency (Northern Ireland).

UK Hydrological Summary for April 2015 published - 15 May 2015

For most of the UK, April 2015 was a largely dry and sunny month, the sunniest on record from 1929 and warmer than average. With much of southern Britain receiving little appreciable rainfall, soil moisture deficits increased markedly above the late April average. River flows and groundwater recessions were mostly sustained through the month although a majority of index catchments and boreholes remained within the normal range.

Climate change and water in the UK past changes and future prospects was published in special issue of Progress in Physical Geography. The paper reviews the impact of anthropogenic climate change on water in the UK and looks at projections of future change. The special issue also features the paper “Climate-driven changes in the UK river flows: A review of the evidence”, authored by Jamie Hannaford of the NRFA. The paper assess the evidence for climate change influences on UK river flow, including floods and droughts.

Integrated Hydrological Units of the United Kingdom dataset released - 18 February 2015

A new freely available dataset of spatial reference units for hydrological purposes, called "Integrated Integrated Hydrological Unit MapHydrological Units of the United Kingdom" has been released. The dataset will aid hydrological analysis and water management in the UK by providing a consistent, nationwide framework for segregating river catchments into component parts. It also serves as a reference list of major river names and, by indicating which units are connected, it can be used to trace the flow of rivers across the country.
