Geography of Sudan
Overview of the geography of Sudan

Sudan is located in Northeast Africa. It is bordered by Egypt to the north, the Red Sea to the northeast, Eritrea and Ethiopia to the east, South Sudan to the south, the Central African Republic to the southwest, Chad to the west and Libya to the northwest. Covering 1,857,392 km2 (717,143 sq mi), it is the third largest country in Africa, after Algeria and the Democratic Republic of the Congo. It was the largest country on the continent until South Sudan split off from it in 2011.
Geographical regions
Northern Sudan – lying between the Egyptian border and Sennar – has two distinct parts, the desert and the Nile Valley. To the east of the Nile is the Nubian Desert and to the west, the Libyan Desert. Both are stony, with sandy dunes drifting over the landscape. There is virtually no rainfall in these deserts. Water in the Libyan desert is limited to a few small watering holes, such as Bir an Natrun, where the water table reaches the surface to form wells that provide water for nomads, caravans, and administrative patrols, although insufficient to support an oasis and inadequate to provide for a settled population. The Nubian Desert has no oases.
Begin with the source’s own compact description: “Geography of Sudan” is overview of the geography of Sudan. The dossier treats that line as a proposition to test through Geography, Sudan and Overview, not as a finished interpretation.
Why this record matters
The phrase “overview of the geography of Sudan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q777664. Authority coordinates are 15.000, 30.000. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2011.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
