Topography
Sudan topography is generally a broad
plain, with mountains in the northeast near the Red
Sea coast, and mountains near the
southeastern
borders.
The Nile is the dominant
geographical feature of
Sudan as around 70% of the area of the country is
situated
with the Nile River catchment. The Blue
Nile and the White Nile originating, respectively,
in the Ethiopian highlands and the Equatorial lakes,
join in Khartoum to form the Nile River which flows
to Egypt.
The Nile has several tributaries and extensive
swamps in the south. River Nile is the longest River
in the world, of 6671 km long
(from its remotest
headstream in Burundi to the Mediterranean Sea). It
is shared by
ten countries but about 60% of its
length lies within Sudan.
