Limpopo River Australopithecus fossils from 3.5 million years ago. St Vincent Whitshed Erskine, later Surveyor General for South Africa, traveled to the mouth of the river in 1868-69. A Zambezi shark ("Carcharhinus leucas") was caught hundreds of kilometres upriver at the confluence of the Limpopo and Luvuvhu Rivers in July 1950. Zambezi sharks tolerate fresh water and can travel far up the Limpopo. In 2013, approximately 15,000 Nile crocodiles were released into the river from flood gates at the nearby Rakwena Crocodile Farm. Limpopo River The Limpopo River rises in South Africa, and flows generally eastwards to the Indian Ocean in Mozambique.
Subsurface flow where infiltration occurred, under the force of gravity or gravity induced pressures. Groundwater tends to move slowly, and is replenished slowly, so it can remain in aquifers for thousands of years. Mainly, water flows through the ground which leads to the ocean where the cycle begins again. Flow within the soil body may take place under unsaturated conditions, but faster subsurface flow is associated with localized soil saturation.* Subsurface flow Subsurface flow, in hydrology, is the flow of water beneath earth's surface as part of the water cycle. In the water cycle, when precipitation falls on the earth's land, some
