Sobat River basin
The Sobat River is a river of the Greater Upper Nile region in northeastern South Sudan , Africa . It is the most southerly of the great eastern tributaries of the White Nile , before the confluence with the Blue Nile .
Geography
The Sobat River is formed by the confluence of the west-flowing Baro River and the north-flowing Pibor River , on the border with Ethiopia . The river enters the White Nile at Doleib Hill , near the city of Malakal in Upper Nile State .
When in flood the Sobat River produces an enormous discharge carrying a white sediment, which gives the White Nile its name.[ 1]
Hydrology
The Sobat and its tributaries drain a watershed approximately 225,000 km2 (87,000 sq mi) in size. The river's mean annual discharge is 412 m³/s (14,550 ft³/s).[ 2]
