This file is a shapefile with polygons defining hydrological watersheds (subbasins) with an average size of 215 km2 and the hydrological links (direction of flow) between them. The subbasins were automatically derived using the WHIST tool to delineate watersheds using the hydrologically corrected DEMs Hydrosheds (and Hydro1K north of 60 degrees). Some manual adjustments were made. The data has been quality checked against published values of catchment areas for European gauging stations. Original data source was HydroSHEDS Hydro1k and WHIST was used for repurposing. The shapefile contains polygons with the following attributes: SUBID (unique ID of the subbasin), HAROID (ID of main river catchment, DOWN (ID of the downstream SUBID) , AREA (Area of subbasin in m2)
