Hydrological basins of South Sudan
This dataset divides the South Sudan according to its hydrological characteristics: major hydrological basins and their sub-basins It identifies eighteen sub-basins as follows: Akoba, Bahr al arab, Buhayrat abyad, Gelha, Khawr biban, Khawr tunbak, Khawr_marchar, Kidepo, Kwahr as sidrah, Kwahr mâ boloko, Lake turkana, Lotagipi swamp, Sopo, Sue, White nile 3, White nile 4, White nile 5 and White nile 6.
The dataset provides information on: numerical code and name of the major basin (MAJ_BAS and MAJ_NAME); - area of the major basin in square km (MAJ_AREA); and numerical code and name of the sub-basin (SUB_BAS and SUB_NAME).
The dataset comes from the HydroSHEDS (Hydrological data and maps based on SHuttle Elevation Derivatives at multiple Scales) of the US Geological Survey. The USGS HydroSHEDS is based on high-resolution elevation data obtained during a Space Shuttle flight of NASAâs 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.

- Statement
- The majority of 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). Areas north of the SRTM extent, 60 degrees N, were obtained by merging with the HYDRO1k basin layer.
