This datapackage contains the outputs from WP5 experiment 1.0 for the wflow_sbm hydrological model (van Verseveld et al., 2022; https://www.deltares.nl/en/software-and-data/products/wflow), which was developed at Deltares, for the test period 1990 - 2021 for the 4DHydro benchmark regions Rhine and Po. The model is forced with the EMO-1 meteorological forcing (https://data.jrc.ec.europa.eu/dataset/0bd84be4-cec8-4180-97a6-8b3adaac4d26), using the Hargreaves method to determine the potential evaporation (a required variable for wflow_sbm). The output consists of the model variables discharge, soil moisture, evapotranspiration and total water storage for these regions at three different model resolutions: 30 arcsecond (approximately 1 km), 2 arcminutes (approximately 4 km) and 4 arcminutes (approximately 8 km). See https://opensciencedata.4dhydro.eu/ for a STAC catalog with links to outputs from other models. Outputs are formatted according to the 4dHydro working package 2 storage protocol (Droppers & Rakovec et al., 2024).
