See also:JUBA, or JUB , a See also:river of See also:East See also:Africa, exceeding r000 m. in length, rising on the S.E. border of the Abyssinian See also:highlands and flowing S. across the Galla and Somali countries to the See also:sea. It is formed by the junction of three streams, all having their source in the See also:mountain range N.E. of See also:Lake See also:Rudolf which is thewater-parting between the See also:Nile See also:basin and the See also:rivers flowing to the See also:Indian Ocean.
Of the three headstreams, the See also:Web, the Ganale and the Daua, the Ganale (or Ganana) is the central river and the true upper course of the Juba. It has two See also:chief branches, the See also:Black and the See also:Great Ganale. The last-named, the most remote source of the river, rises in 7° 3o' N., 38° E. at an See also:altitude of about 7500 ft., the See also:crest of the mountains reaching another 2500 ft. In its upper course it flows over a rocky See also:bed with a See also:swift current and many rapids. The See also:banks are clothed with dense See also:jungle and the hills beyond with See also:thorn-See also:bush. See also:Lower down the river has formed a narrow valley, 1500 to 2000 ft. below the See also:general level of the See also:country. Leaving the higher mountains in about 50 15' N., 40° E., the Ganale enters a large slightly undulating grass See also:plain which extends See also:south of the valley of the Daua and occupies all the country eastward to the junction of the two rivers. In this plain the Ganale makes a semicircular sweep northward before resuming its general S.-E. course. East of 42° E. in 4° 12' N. it is joined by the Web on the See also:left or eastern See also:bank, and about Io m. lower down the Daua enters on the right bank.
The Web rises in the mountain See also:chain a little S. and E. of the See also:sources of the Ganale, and some 40 m. from its source passes, first, through a See also:canon 500 ft. deep, and then through a See also:series of remarkable underground caves hollowed out of a See also:quartz mountain and, with their See also:arches and See also: The Daua (or Dawa) is formed by the mountain torrents which have their rise S. and W. of the Ganale and is of similar See also:character to that river. It has few feeders and none of any See also:size. The descent to the open country is somewhat abrupt. In its See also:middle course the Daua has cut a deep narrow valley through the plain ; lower down it bends N.E. to its junction with the Ganale. The river is not deep and can be forded in many places; the banks are fringed with thick bush and dom-palms. At the junction of the Ganale and the Web the river is swift-flowing and 85 yards across; just below the Daua confluence it is 200 yds. wide, the altitude here—3oo m. in a See also:direct See also:line from the source of the Ganale—being only 590 ft. Below the Daua the river, now known as the Juba, receives no tributary of importance. It first flows in a valley bounded, especially towards the See also:west, by the escarpments of a high See also:plateau, and containing the towns of Lugh (in 3° 50' N., the centre of active See also:trade), Bardera, 387 in. above the mouth, and Saranli—the last two on opposite sides of the stream, in 2 ° 20' N., a See also:crossing-See also:place for caravans. Beyond 1 ° 45' N. the country becomes more level and the course of the river very tortuous. On the west a series of small lakes and backwaters receives See also:water from the Juba during the rains. Just south of the See also:equator channels from the See also:long, branching Lake Deshekwama or See also:Hardinge, fed by the Lakdera river, enter from the west, and in o° 15' S. the Juba enters the sea across a dangerous See also:bar, which has only one See also:fathom of water at high See also:tide. From its mouth to 20 M. above Bardera, where at 2° 35' N. rapids occur, the Juba is navigable by shallow-See also:draught steamers, having a general See also:depth of from 4 to 12 ft., though shallower in places. Just above its mouth it is a See also:fine stream 250 yds. wide, with a current of 21 knots. Below the mountainous region of the headstreams the Juba and its tributaries flow through a country generally arid away from the banks of the streams. The See also:soil is sandy, covered either with thorn-scrub or See also:rank grass, which in the See also:rainy See also:season affords herbage for the herds of See also:cattle, See also:sheep and camels owned by the Boran See also:Gallas and the Somali who inhabit the See also:district. But by the banks of the lower river the character of the country changes. In this district, known as Gosha, are considerable tracts of See also:forest, and the level of See also:flood water is higher than much of the surrounding See also:land. This See also:low-lying fertile See also:belt stretches along the river for about 300 m., but . is not more than a mile or two wide. In the river valley See also:maize, See also:rice, See also:cotton and other crops are cultivated. From Gobwen, a trading See also:settlement about 3 m. above the mouth of the Juba, a road runs S.W. to the seaport of Kismayu, to in. distant. The lower Juba was ascended in 1865 in a steamer by See also:Baron Karl von der Decken, who was murdered by Somali at Bardera, but the river See also:system remained otherwise almost unknown until after 1890. In 1891 a survey of its lower course was executed by See also:Captain F. G. Dundas of the See also:British See also:navy, while in 1892–1893 its headstreams were explored by the See also:Italian See also:officers, Captains See also:Vittorio, Bottego and Grixoni, the former of whom disproved the supposed connexion of the Omo (see RUDOLF, LAKE) with the Juba system. It has since been further explored by See also:Prince Eugenio Ruspoli, by Bottego's second expedition (1895), by See also:Donaldson See also: Additional information and CommentsThere are no comments yet for this article.
