Water Atlas of the Main Nile Sub-Basin

The One System Inventory (OSI) Water Atlases are prepared for the four main sub-basins of the Eastern Nile: Abay-Blue Nile, Baro-Akobo-Sobat-White Nile, Tekeze-Atbara-Setit, and Main Nile. The Atlases are essentially provided with maps, charts and general information/brief descriptions about the sub-basins land, climate, hydrology, infrastructure and utilities, and few environmental issues. The sub-basin maps included are location, administrative, population density, elevation, shaded relief, terrain/landscape classification, surficial geology, dominant soils, rainfall, temperature, evaporation, humidity, sub-catchment drainage network, runoff, vegetation cover, landuse/landcover, isoerodent/sediment yield and malaria-prone areas. Whereas schematics of indicative water balance are presented for the main rivers of the EN sub-basins, maps showing existing and potential irrigation and hydropower projects are not incorporated.
