Africa - HydroBasin - vectorized polygon layers of hydrographic basins

Major hydrological basin boundaries across Africa delineated from hydrologically corrected elevation data derived from HydroSHEDS and Hydro1K datasets. Each polygon represents a drainage basin defined by its watershed boundary, with attributes for basin name, area, and sub-basin coding. Use this layer for transboundary water governance, river basin management, flood risk assessment, water resource planning, and catchment-level environmental analysis across Africa. No additional information provided.

This dataset represents the Level 5 delineation of the Shabelle River Basin in Ethiopia, as defined by the HydroBASINS framework. The Level 5 (L5) subdivision provides a mid-scale segmentation of the Shabelle Basin, capturing key hydrological structures while maintaining computational efficiency.

Rivers, streams and drainage network of Ethiopia showing the extent and hierarchy of surface water features. Use this layer for watershed analysis, flood modelling, irrigation planning, water resource mapping, and environmental impact assessment.

This dataset divides the African continent in major hydrological basins and their sub-basins according to its hydrological characteristics. It was obtained by delineating drainage basin boundaries from hydrologically corrected elevation data (WWF HydroSHEDS and Hydro1K). The dataset consists of the following information:- numerical code and name of the major basin (MAJ_BAS and MAJ_NAME); - area of the major basin in square km (MAJ_AREA); - numerical code and name of the sub-basin (SUB_BAS and SUB_NAME); - area of the sub-basin in square km (SUB_AREA); - numerical code of the sub-basin towards which the sub-basin flows (TO_SUBBAS) (the codes -888 and -999 have been assigned respectively to internal sub-basins and to sub-basins draining into the sea) **Data publication:** 2021-12-15 **Supplemental Information:** This dataset is developed as part of a GIS-based information system on water resources for the African continent. It has been published in the framework of the AQUASTAT - programme of the Land and Water Division of the Food and Agriculture Organization of the United Nations. **Contact points:** Metadata Contact: [AQUASTAT](mailto:aquastat@fao.org) Resource Contact: [Jippe Hoogeveen](mailto:jippe.hoogeveen@fao.org) **Data lineage:** The linework of the map was obtained by delineating drainage basin boundaries from hydrologically corrected elevation data with a resolution of 15 arc-seconds.The elevation dataset was part of a mapping product, HydroSHEDS, developed by the Conservation Science Program of World Wildlife Fund. Original input data had been obtained during NASA's Shuttle Radar Topography Mission (SRTM).
