This dataset is a model output, from the Grid-to-Grid hydrological model driven by observed climate data (CEH-GEAR rainfall and Oudin temperature-based potential evaporation). It provides monthly mean flow (m3/s) and soil moisture (mm water/m soil) on a 1 km grid for the period 1891 to 2015.
To aid interpretation, two additional spatial datasets are provided:
• Digitally-derived catchment areas on a 1km x 1km grid
• Estimated locations of flow gauging stations on a 1km x 1km grid and as a csv file.
The data were produced as part of MaRIUS (Managing the Risks, Impacts and Uncertainties of drought and water Scarcity), which was a UK NERC-funded research project (2014–2017) that developed a risk-based approach to drought and water scarcity (http://www.mariusdroughtproject.org/).

The flow and soil moisture estimates are output from the Grid-to-Grid hydrological model (Bell et al. 2009; doi:10.1016/j.jhydrol.2009.08.031). The meteorological inputs to the model were rainfall from CEH-GEAR (Tanguy et al. 2016; doi:10.5285/33604ea0-c238-4488-813d-0ad9ab7c51ca) and potential evaporation derived from 5km temperature data (Perry and Hollis, 2005, doi:10.1002/joc.1161) using the method of Oudin et al. (2005; https://doi.org/10.1016/j.jhydrol.2004.08.026). See Supporting Information for more details.
