South African soil, land cover and weather generator file databases for SWAT

This study provides multiple geo-spatial datasets at a national scale for use as baseline input to run ArcSWAT (graphical user interface for SWAT in ArcGIS) or QSWAT (graphical user interface for SWAT+ in QGIS) in South Africa. The input datasets include the following:
• SWAT catchment outline data (tertiary and quaternary);
• Land cover maps at 20-30 m resolution including South African National Land Cover (2014; 2018; 2020) linked to SWAT land cover codes;
• A soil map with SWAT attribute data derived from pedotransfer functions of the Land Type Database of South Africa useable at a scale of 1:250,000;
• Weather statistics (WGN) files for 12 weather stations obtained from the Agricultural Research Council in South Africa.
