The Limpopo River () rises in South Africa and flows generally eastward through Mozambique to the Indian Ocean. The term Limpopo is derived from Rivombo (Livombo/Lebombo), a group of Tsonga settlers led by Hosi Rivombo who settled in the mountainous vicinity and named the area after their leader. The river has been called the Vhembe by local Venda communities of the area where now that name has been adopted by the South African government as its District Municipality in the north, a name that was also suggested in 2002 as a possible title for the province but was voted against. The river is approximately 1,750 km (1,090 mi) long, with a drainage basin of 415,000 km2 (160,000 mi2) in size. The mean discharge measured over a year is 170 m3/s (6,000 cu ft/s) to 313 m3/s (11,100 cu ft/s) at its mouth. The Limpopo is the second largest African river that drains to the Indian Ocean, after the Zambezi River. The first European to sight the river was Vasco da Gama, who anchored off its mouth in 1498 and named it Rio do Espírito Santo (lit. 'River of the Holy Spirit'). Its lower course was explored by St Vincent Whitshed Erskine in 1868–69, and Captain J F Elton travelled down its middle course in 1870. The drainage area of Limpopo River has decreased over geological time. Up to Late Pliocene or Pleistocene times, the upper course of the Zambezi River drained into the Limpopo River. The change of the drainage divide is the result of epeirogenic movement that uplifted the surface north of present-day Limpopo River, diverting waters into Zambezi River.
