There are two major river systems in South Africa – the Orange (including its main tributary, the Vaal River) which flows westward into the Atlantic Ocean and forms part of South Africa’s border with Namibia, and the Limpopo, which flows eastward into Mozambique toward the Indian Ocean and forms part of South Africa’s border with Botswana and Zimbabwe. Besides these, there are many smaller rivers in the southern part of the country that flow southward into either the Indian or Atlantic Ocean.
