Mongalla

Geography

Mongalla lies about by road northeast of Juba on the road to Bor in the north, but nearer as the crow flies. Mongalla is situated on the east bank of the White Nile in Central Equatoria state at an altitude of . Rainfall is relatively low between November and February, then increasing with two peaks in June and August. Annual precipitation is about . Winds are northerly in the dry season and southerly in the rainy season. Based on observations taken between April 1903 and December 1905, the mean temperature was , with mean maximum and mean minimum . Mean relative humidity was 74%. The river flowing past Mongalla combines seasonal torrential runoff in the rainy season with the more constant discharge from Lake Victoria, influenced by evaporation and by the damping and storage effects of Lake Albert, Lake Edward and Lake Kyoga. The Sudd, a vast area of swampland, stretches downriver from Mongalla to near the point where the Sobat River joins the White Nile just upstream from Malakal. Due to evaporation, only half the water that enters the Sudd at Mongalla emerges from the northern end of the swamps. The much smaller Badigeru Swamp lies about to the east, separated from Mongalla by a region of open grassland. The belt along the Nile about 10 km wide and 146 km long from Mongalla to Bor is inhabited by the Mundari and Dinka peoples.
