The Sudans
The Sudans (sometimes also known as the two Sudans ) is a region in the Africa comprising the countries of Sudan and South Sudan.
Sudan is situated in northern Africa, with a 853 km (530 mi) coastline bordering the Red Sea. With an area of 2,505,810 km2 (967,499 sq mi), it is the second largest country on the continent (a status it lost to Algeria when South Sudan became independent on 9 July 2011) and the ninth largest in the world. The Sudans lie mostly between latitudes 3° and 22°N (the Wadi Halfa Salient and disputed Hala'ib triangle are north of 22°), and longitudes 21° and 39°E.
The terrain is generally flat plains, broken by several mountain ranges; in the west the Jebel Marra is the highest range; in the south is the highest mountain, Mount Kinyeti Imatong (3,187 m or 10,456 ft), near the border with Uganda; in the east are the Red Sea Hills.
The Blue and White Nile rivers meet in Khartoum to form the River Nile, which flows northwards through Egypt to the Mediterranean Sea. The Blue Nile's course through the Sudans is nearly 800 km (497 mi) long and is joined by the Dinder and Rahad Rivers between Sennar and Khartoum. The White Nile within the Sudans has no significant tributaries.
