Answer:
Ethiopia is endowed with a substantial amount of water resources. The surface water resource potential is impressive, but little developed. The country possesses 12 major river basins, which form four major drainage systems: -The Nile basin (including Abbay or Blue Nile, Baro-Akobo, Setit-Tekeze/Atbara and Mereb) covers 33 per cent of the country and drains the northern and central parts westwards; -The Rift Valley (including Awash, Denakil, Omo-Gibe and Central Lakes) covers 28 per cent of the country; -The Shebelli-Juba basin (including Wabi-Shebelle and Genale-Dawa) covers 33 per cent of the country and drains the southeastern mountains towards Somalia and the Indian Ocean; -The North-East Coast (including the Ogaden and Gulf of Aden basins) covers 6 per cent of the country.
