Hydrological projections for the UK, based on UK Climate Projections 2018 (UKCP18) data, from the Enhanced Future Flows and Groundwater (eFLaG) project
Enhanced Future Flows and Groundwater (eFLaG) is an 12-member ensemble projection of river flow, groundwater level, and groundwater recharge time series for 200 catchments, 54 boreholes and 558 groundwater bodies in Great Britain and Northern Ireland. It is derived from the UKCP18 dataset, specifically the 'Regional' 12km projections, to which a bias correction is applied. River flows, groundwater level and groundwater recharge data are at a daily time step.
To be consistent with the driving meteorological dataset, eFLaG data use a simplified 360-day year, consisting of twelve 30-day months. eFLaG data span from 1981 to 2080.
The development of eFLaG was made during the partnership project funded by the Met Office-led component of the Strategic Priorities Fund Climate Resilience programme under contract P107493 (CR19_4 UK Climate Resilience).

Provenance & quality
Meteorological data is from the UKCP18 dataset, specifically the ‘Regional’ 12km projections. Observed river flow and groundwater level data are provided by the NRFA (National River Flow Archive) and NGLA (National Groundwater Level Archive) respectively. Meteorological and observed data is then modelled through a number of systems including AquiMod, ZOODRM, G2G, PDM, GR4J.
