Dealing with Sub-pixel Landscape Elements in Distributed Rainfall-Runoff Modelling in Agricultural Catchments

The <strong>Input_Data.zip</strong> file contains the processed data used as input data for the research paper "<strong>Dealing with Sub-pixel Landscape Elements in Distributed Rainfall-Runoff Modelling in Agricultural Catchments</strong>". The <strong>Digital Elevation Models (DEMs)</strong> are adapted from the 5 m resolution "DEM DHMV II" (available from https://download.vlaanderen.be/Producten/Detail/938). The scaling factors used to calculate per-pixel values of upscaled hydro-physical parameters are derived from the digital elevation model. The raster files representing the <strong>Manning's roughness coefficient</strong> in the watershed for 2006, 2007, 2013, 2016 and 2019 are based on landcover datasets created by combining the Flemish agricultural parcel dataset for each year (available from https://www.vlaanderen.be/datavindplaats/catalogus/landbouwgebruikspercelen-lv-2021) with the road network dataset (available from https://www.vlaanderen.be/digitaal-vlaanderen/onze-oplossingen/basiskaart-vlaanderen-grb) and digitised polygons of forested areas based on areal images (https://www.vlaanderen.be/datavindplaats/catalogus/orthofotomozaiek-grootschalig-winteropnamen-kleur-2013-2015-vlaanderen). The <strong>vegetated landscape element (vLE) configurations</strong> were created based on agricultural parcel boundaries (available from https://www.vlaanderen.be/datavindplaats/catalogus/landbouwgebruikspercelen-lv-2021) and rasterising them. <strong>Rainfall intensity measurements</strong> were extracted from waterinfo.be for the station with name "Niel-bij-St.-Truiden_P", number "01P09_012", and coordinates (LAT/LON) "50.7378581908062/5.14225742349451". <strong>Discharge measurements </strong>were extracted from waterinfo.be for the discharge station with name "Gingelom/Heulegracht" and number "LS09_15F". The <strong>scripts.zip</strong> file contains the scripts used to process the data. The Output.zip file contains the output files created by the scripts while making use of the Python-based Landlab model environment (https://landlab.github.io/#/) This research was funded by Fonds Wetenschappelijk Onderzoek (FWO), grant number 1SB6821N.
