Abstract/Additional Information

In 1998, the Eikenhof dam in South Africa was heightened by 2 m, increasing the storage capacity by 19 per cent to 29×106 m3. The project combined a fixed reinforced concrete labyrinth on the service spillway with straight-crested reinforced concrete Hydroplus fusegates on the auxiliary spillway sill, allowing the designers to improve the overall safety levels for the dam, while leaving the embankment crest level unchanged. Storage was increased by approximately 4.5×106 m3, for a total project cost of US$250 000.
