RUFIJI , a large See also:river of See also:German See also:East See also:Africa, entering the See also:sea by a considerable See also:delta, between 70 45' and 8° 13' S. Its upper See also:basin, which extends from N. to S. through over 300 m., is drained by three See also:main branches, which unite to See also:form the See also:lower Rufiji. Of the three upper branches, the two See also:southern, the Luvegu and the Ulanga, though shorter than the See also:northern-most (the Ruaha), carry a greater See also:volume of See also:water, as they come from a more See also:rainy region, and by their junction in 8° 35' S., 370 25' E., the Rufiji proper may be said to be formed. The Luvegu rises 10° 50' S., 35° 50' E., and flows N.E. in a wooded valley, generally narrow, and bordered by a broken See also:country in See also:great See also:part uninhabited and covered with thin See also:forest. In' its lower course it is a large stream—too to 150 yds. wide. The Ulanga is formed by a number of streams descending from the See also:outer escarpment of the high See also:plateau which runs N.E. from the See also:head of See also:Lake See also:Nyasa and in Uhehe becomes broken up ,in ranges of mountains. The most important head-stream, the Ruhudye, rises in about 9° 30' S., 34° 40' E. As a whole, the Ulanga valley is broad, level and swampy, the river See also:running in a very winding course and sending off many diverging arms. It is navigable throughout the greater part of its course, having even in the dry See also:season a See also:general See also:depth of 3 to 12 ft., with a width of 40 to 120 yds. In See also:April and May nearly all the streams overflow their See also:banks and See also:cover a great part of the See also:plain. Just below the junction of the Luvegu and Ulanga, the Rufiji flows through a narrow pass by the Shuguli falls, and continues N.E. in a fairly straight course to the junction of the' Ruaha, in 7° 55' S., 37° 52' E. The most remote branches of the Ruaha rise N. of Lake Nyasa in the See also:Livingstone mountains. The See also:united stream makes a wide sweep to the N. of the Uhehe mountains,' from which it receives various tributaries, finally flowing S.E. and E. to the ,Rufiji. A little below the junction the Rufiji is broken by the Pangani falls, but is thence navigable by small steamers to its delta. In this part of its course the river receives no large tributaries but sends out divergent channels. The country on either See also:side is a generally level plain, inundated, on the See also:south, in the rains, and the river varies in width from too to 400 yds., with an See also:average current of 3 M. an See also:hour. The main mouth of the river is that known as Simba Uranga, the See also:bar of which can be crossed by ocean vessels at high water, but all the branches are very shallow as the See also:apex of the delta is approached. Much of the delta is suited for See also:rice-growing. Additional information and CommentsThere are no comments yet for this article.
