Sub-basins of South Sudan

This dataset of sub-basins comes from the USGS HydroSHEDS layers and identifies the following eighteen sub-basins: Akoba, Bahr al arab, Buhayrat abyad, Gelha, Khawr biban, Khawr tunbak, Khawr_marchar, Kidepo, Kwahr as sidrah, Kwahr m’ boloko, Lake turkana, Lotagipi swamp, Sopo, Sue, White nile 3, White nile 4, White nile 5 and White nile 6. The HydroSHEDS are hydrological data and maps based on SHuttle Elevation Derivatives at multiple Scales of the US Geological Survey. The USGS HydroSHEDS layer is based on high-resolution elevation data obtained during a Space Shuttle flight of NASA’s Shuttle Radar Topography Mission (SRTM). Around twenty-three sub-basins fall in the South Sudan area, including five sub-basins of which only a small portion is comprised. They are part of two main hydrological basins: the biggest part of the study area belongs to the Nile basin, while the eastern part of the area belongs to the Rift Valley basin. The delineation of the hydrological basins can be considered as the starting point in the analysis of the hydrological cycle to study surface water resources systems.
