The Rovuma (other spellings Ruvuma , Rowuma ) is an approximately 760 km long river in East Africa . In its middle and lower reaches, the Rovuma forms the border between Tanzania and Mozambique over a length of around 650 kilometers .

geography

The Rovuma rises east of Lake Malawi (Njassasee) in Tanzania near Songea at 10 ° 45 ′ 0 ″ S, 35 ° 40 ′ 0 ″ E and flows between the Tanzanian coastal town of Mtwara and Cape Delgado at 10 ° 28 ′ 28 ″ S, 40 ° 26 ′ 13 ″ E in the Indian Ocean .

The most important tributaries on the Tanzanian side are Muhuwesi and Lumesule and Lucheringo and Lugenda in Mozambique. The unified bridge at Negomane , which opened in May 2010, is the only possible crossing for vehicles along the river.

The catchment area of ​​the Ruvuma has, depending on the source, a size of 152,200 km² to 155,500 km, of which approximately 105,500 km² are located on Tanzanian territory.

history

The crossing of the Rovuma on November 25, 1917 is a military-historical event of the First World War in East Africa . As a result, the commander-in-chief of the German Schutztruppe for German East Africa , Paul von Lettow-Vorbeck , escaped premature surrender and continued to fight partly on opposing territory until the end of the First World War.

After the end of German East Africa , the mouth of the Rovuma formed the border between the British Mandate Tanganyika and Portuguese East Africa . Before that, a small area south of the estuary, the so-called Kionga triangle , belonged to German East Africa.
