Low Flows 2000
Low Flows 2000 is a decision support tool designed to estimate river flows at ungauged sites and to aid the development of catchment and regional water resources. It is the standard software system used by the Environment Agency and the Scottish Environment Protection Agency for providing estimates of river flows, as represented by annual and monthly flow duration statistics, for any river reach in the UK. The software and underpinning science have been widely published in the scientific literature.
The CEH Low Flows 2000 system is now licensed to Wallingford HydroSolutions (WHS) for distribution and further development. WHS was set up in 2004 to maximise the transfer of CEH water research to the user community.
