Ruvuma River Flowing Along Tanzania-Mozambique Border10.5S 39.9E
Ruvuma River, formerly also known as the Rovuma River, is a river in East Africa, forming during the greater part of its course the border between Tanzania and Mozambique (in Mozambique known as Rio Rovuma).
It is 800 kilometres (497 mi) long, with a drainage basin 155,500 square kilometres (60,000 sq mi) in size. Its mean annual discharge is 475 m³/s (16,774 cfs) at its mouth.
The lower Ruvuma, which is often half a mile wide but generally shallow, flows through a swampy valley flanked by plateau escarpments containing several small backwaters of the river.
