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 met

Useful for
- Use cases llm-inferred
- Future river flow projections for flood risk assessment and climate change allowances on river catchments · Water resources and drought assessment using projected river flows and groundwater levels · Groundwater recharge and borehole level projections for groundwater risk assessment · Climate change scenario inputs for drainage and water supply strategy studies

Limitations
- Constraints docs-verified
- Simplified 360-day year (twelve 30-day months), not the Gregorian calendar · Model projections rather than observations; 12-member ensemble · Bias-corrected from 12 km UKCP18 Regional projections · Scripted downloads require a personal access token
