Grid-to-Grid model simulations of daily anthropogenically influenced river flows for England and natural flows for Great Britain, 1961-2021.

dcterms:description "The datasets provide Grid-to-Grid (G2G) hydrological model estimates of daily mean river flow (m3s-1) on a 1 km x 1 km grid. The river flows provided here are generated using the G2G model for Great Britain driven by observation-based meteorological data. They provide spatially consistent simulations of natural and anthropogenically influenced daily mean river flows. The natural flows are for the period 1st January 1961 to 31st December 2021, the observed-anthropogenically influenced flows are for 1st January 1999 to 31st December 2014 and the mean-anthropogenically influenced flows are for 1st January 1961 to 31st December 2021. The G2G hydrological model spatial river flow simulations are available as follows: (a) Natural river flows across the whole of Great Britain, excluding Orkney and Shetland islands (b) Anthropogenically influenced river flows across the whole of England" ;
dcterms:provenance [
a dcterms:ProvenanceStatement ;
rdfs:label "The Grid-to-Grid model (G2G) is a grid-based, spatially distributed hydrological model which has recently been enhanced to take account of recorded monthly abstractions and annual discharges. While in practice, hydrological modelling has been undertaken for mainland Britain, model estimates for anthropogenically influenced catchments are only available for English catchments, albeit with a modest overlap of the Welsh border. This is because, to date, abstraction and discharge data are only available for England."
