Future Flows Hydrology (FF-HydMod-PPE) is an 11-member ensemble projections of river flow and groundwater levels time series for 283 catchments and 24 boreholes in Great Britain. It is derived from Future Flows Climate, an 11-member 1-km bias-corrected and downscaled climate projection products based on the SRES A1B emission scenario. River Flows data are at a daily time step: Groundwater Levels data are at a monthly time step. Future Flows Hydrology span from 1951 to 2098. The development of Future Flows Hydrology was made during the partnership project 'Future Flows and Groundwater Levels' funded by the Environment Agency for England and Wales, Defra, UK Water Research Industry, NERC (Centre for Ecology & Hydrology and British Geological Survey) and Wallingford HydroSolutions.

An 11-member ensemble of daily river flow and monthly groundwater levels for 283 river catchments and 24 boreholes across Great Britain simulated in March 2012. Future Flows Hydrology time series are generated using conceptual hydrological models driven by Future Flows Climate and span the period 1951-2098. Each ensemble set contains 11 members all equally likely that together accounts for climate variability, climate modelling uncertainty and climate forcing under the SRES A1B emissions scenario. As Future Flows Hydrology datasets are driven by forcing from climate model outputs they do not replicate the historical weather but are possible realisations of river flow and groundwater levels time series. Despite the use of bias-corrected Future Flows Climate as input and local hydrological models Future Flows Hydrology dataset might still contain hydrological and climate modelling errors and cannot be compared directly with gauged values.
