Sobat River
The Sobat River is a river in northeastern South Sudan, Africa, that is part of the Greater Upper Nile region. It is the most southerly of the White Nile's great eastern tributaries before it joins the Blue Nile (White Nile and Blue Nile are two main tributaries of Nile River- a major north-flowing river in northeastern Africa and Africa's longest river)
On the border with Ethiopia, the Sobat River is formed by the confluence of the west-flowing Baro River and the north-flowing Pibor River. The river enters the White Nile near Malakal in Upper Nile State at Doleib Hill.
When the Sobat River floods, it produces a massive discharge of white sediment, giving rise to the name "White Nile."
The Sobat and its tributaries drain an area of about 225,000 km2 (87,000 sq mi). The average annual discharge of the river is 412 m³/s (14,550 ft³/s).
Length: 354 km (220 mi)
