摘要

Innovative technology has recently been used for heightening the Ruti dam, located in a semi-arid region of Zimbabwe. The additional storage capacity will be used to irrigate an extra 350 ha of communal farmlands. This paper emphasizes the role played by the project to improve the livelihood and to reduce poverty by ensuring a regular source of income to local communities from greater irrigation. Zimbabwe's Ministry of Rural Resources and Water Development (MRRWD) signed, on 30 December 1998, a contract with Hydroplus for the supply and installation of the fusegate system, with Safege being retained for engineering design and supervision of the works. The design was initiated in September 1999, and site works started in May 2000. The project was commissioned in February 2001. The very large (693 m) spillway required the installation of 256 fusegates, 1.5 m high by 2.7 m wide, in a labyrinth crested configuration. A noteworthy feature was the use of buttresses to strengthen the masonry saddle spillway. At Ruti, the fusegate system allowed for increasing the full supply level by 1.6 m without any restriction in the discharge capacity of the spillway. The storage capacity has been increased by 25.7 x 10~6m~3 (a 20 per cent increase in the pre-existing storage).
