Shashe River
The Shashe River (or Shashi River) is a major left-bank tributary of the Limpopo River in Zimbabwe. It rises northwest of Francistown, Botswana and flows into the Limpopo River where Botswana, Zimbabwe and South Africa meet. The confluence is at the site of the Greater Mapungubwe Transfrontier Conservation Area.
Hydrology
The Shashe River is a highly ephemeral river, with flow generally restricted to a few days of the year. The river contributes 12.2% of the mean annual runoff of the Limpopo Basin.
Major tributaries of the Shashe River include the Simukwe, Shashani, Thuli, Tati and Ramokgwebana rivers. The lower Shashe is a sand filled channel, with extensive alluvial aquifers in the river channel and below the alluvial plains. These supply water for a number of irrigation schemes including Sibasa and Shashi.
More than two million years ago, the Upper Zambezi River used to flow south through what is now the Makgadikgadi Pan (presently a vast seasonal wetland) to the Shashe River and thence the Limpopo River.
