River, South Africa.
Rising as the Crocodile (Krokodil) River in the Witwatersrand, South Africa, it flows northeast along the border of South Africa and southeast across Mozambique to empty into the Indian Ocean. Along its middle course it divides South Africa from Botswana and Zimbabwe. It is 1,100 mi (1,800 km) long but is navigable only 130 mi (208 km) from the coast. The first European to visit it was Vasco da Gama , who named its mouth the Espíritu Santo River in 1498.
