CS-NOW: Gridded future projections of natural and artificially influenced river flows (1980 to 2080)
Abstract
The Grid-to-Grid (G2G) river flow model projections comprise an ensemble of natural and artificially influenced (AI) estimates of daily mean river flows (m3s-1). These flow projections are for a historical and future period spanning 1st December 1980 to 30th November 2080 and reflect scenarios of change in both climate and artificial (anthropogenic) influences (abstractions and discharges).
The historical and future projections are available in two formats:
(i) 1 km × 1 km gridded daily mean river flows (m3s-1) for two spatial regions: Natural river flows across Great Britain, and Artificially influenced river flows across England
(ii) Time series of daily flows for 626 catchments across England
The climate projections consist of an ensemble of bias-corrected UKCP18 Regional Climate Model (RCM) output. A further 4 hydrological connectivity datasets provide flow directions, upstream areas and coastal/gauged locations. Further details are provided in a linked Data Document.
Three future scenarios of artificial influences are considered:
(a) Sustainability (SUS),
(b) Business as usual (BAU) and
(c) Economic Growth (EG).
The dataset is an output from the CS-NOW project (Climate services for a Net Zero resilient world - GOV.UK (www.gov.uk)), commissioned by the UK Department for Energy Security and Net Zero (DESNZ). Publication of these data is also supported by the Natural Environment Research Council award number NE/X019063/1 as part of the Hydro-JULES programme delivering National Capability.

| Data lineage: |
This dataset comprise an ensemble of natural and artificially influenced (AI) estimates of daily mean river flows (m3s-1). These flow projections are for a historical and future period spanning 1st December 1980 to 30th November 2080 and reflect scenarios of change in both climate and artificial (anthropogenic) influences (abstractions and discharges). Data were produced by the project team before archival at EDS-CEDA |
| Data Quality: |
Time series of daily mean river flows (m3s-1) are provided in csv format for 626 English gauging stations, and gridded flows are provided in NetCDF format for the period 1st December 1980 to 30th November 2080. The netcdf format data have been checked for CF convention compliance.
Gridded flow estimates are provided for 2 spatial domains:
(i) The gridded data for the NATURAL flows are provided for Great Britain: this is a 601 km × 980 km spatial domain on the British National Grid from lower left corner (55000, 0) to top right (656000, 980000) metres.
(ii) The gridded data for the AI impacted flows are provided for England: this is a smaller 601 km × 660 km spatial domain on the British National Grid from lower left corner (55000, 0) to top right (656000, 660000) metres.
Values for each 1 km × 1 km grid box refer to the river which best represents the 1 km cell.

Process overview
| Title | Grid-to-Grid Model |
| Abstract | The Grid-to-Grid (G2G) is a national-scale grid-based hydrological model which typically operates on a 1km x 1km grid at a 15-minute time-step (Bell et al. 2009). It was originally configured to cover Great Britain (GB) and output natural river flows, but was more recently extended to cover Northern Ireland (NI), and to take account of anthropogenic influences (abstractions and discharges) where available (Rameshwaran et al. 2022). |
