Kariba is in danger of suffering a catastrophic structural failure if repairs are not conducted, and emergency international funding has been secured to repair it. The Kariba Dam is one of Africa’s engineering wonders; 128m tall and 680m long, spanning the Zambezi River on the border between Zambia and Zimbabwe. Erosion in the plunge pool below the dam now threatens the foundations, endangering 3.5 million people downstream.

Construction was started in 1956, financed by the largest World Bank loan ever. The Kariba Dam has a double-arch wall - curved both vertically and horizontally. The arch dam was constructed between 1956 and 1959 and supplies water to two underground hydropower plants located on the north bank in Zambia and on the south bank in Zimbabwe. The spillway consists of six gates through which ZRA releases water into the plunge pool to manage the reservoir water levels.Latest news headlines from Zimbabwe SituationZRA will provide $19,2 million while the African Development Bank and the European Union are expected to inject $75 million and $100 million respectively into the project.

The procurement is expected to be completed in time for the works contract to be awarded by the last quarter of 2018,” said Munyaradzi Munodawafa, the chief executive officer of ZRA.The dam, which has a height of 128 metres, was designed by French engineer and inventor Andre Coyne and was built between 1956 and 1958 by an Italian consortium, Impresit Group.The spillway rehabilitation, which is jointly funded by the World Bank, African Development Bank and the Swedish government, entails the refurbishment of the upstream stop-beam guides and replacement of secondary concrete and the design, fabrication and installation of an emergency gate and a new gantry as additional safety precautions. This is how the people of Zambia and Zimbabwe are struggling to adapt to reports of a possible collapse of the Kariba Dam.The largest tidal power plant in the world will be built in the Larantuka Straits.
