Products and datasets

The project ‘Future Flows and Groundwater Levels’ was set-up to provide datasets and products facilitating the assessment of climate change impact on a range of water-related issues across Great Britain within a nationally consistent framework. Based on the ensemble runs from the Hadley Centre regional climate model HadRM3-PPE, underpinning the UKCP09 scenarios, the following datasets and products have been generated: Future Flows Climate (FF-HadRM3-PPE): 11-member ensemble of 1-km gridded climate time series (available precipitation and potential evapotranspiration) derived for Great Britain from the HadRM3-PPE, the MetOffice Hadley Centre’s Regional Climate Model ensemble output underlying the UKCP09 products; Future Flows Hydrology (FF-HydMod-CatID): 11-member ensemble of daily river flow and monthly groundwater level time series for 282 river sites and 24 boreholes derived from Future Flows Climate using specific hydrological/groundwater level models (HydMod); 11-member ensemble of precipitation and potential evapotranspiration daily catchment average time series for 282 river sites and 24 boreholes derived from Future Flows Climate; national maps (or ‘snap shots’) of changes in river flow statistics (including mean monthly flows and low flow statistics) for most large rivers of Great Britain; regional maps (or ‘snap shots’) of changes in groundwater level and river flow statistics for one region; briefing notes for decision-makers on how to use these results. All those datasets and products are made available through dedicated web pages. Their use is restricted under a licensing condition agreement. Non-commercial use is free; commercial use might be possible conditioned to a fee to be agreed with CEH or BGS licensing team, owner of the IPR of the datasets and products. This report briefly explains the content of each dataset and product and how to access them.
