Dams
| Burnett Catchment Water Infrastructure Project, | ||
Map showing the location of the Burnett Catchment area within Queensland. |
Before dam construction commenced, two stretches of roadway were upgraded to improve access, 16km of the existing roadway to the dam site and 6km serving the approach to Eidsvold Weir. |

The Burnett Catchment area is an important site for wildlife. Many of the shallow vegetated bodies of water are likely to disappear when the inevitable reduction in flow occurs. |

Construction work on the dam began in November 2003 and progress to the following August suggests that it is on target for the scheduled completion date in October 2005. |
The Burnett River Dam project has met with objections on environmental grounds because it is one of the only two habitats in the world for the rare Queensland Lungfish. However, it has also received much support from a variety of sources. |

| Eastside Reservoir Project (Diamond Valley Lake), California | ||
The East Dam of the Eastside Reservoir project, also known as Diamond Valley Lake. |
Map of the Eastside Reservoir project. |
Diamond Valley Lake is the largest reservoir in Southern California and has a capacity to hold about 800,000 acre-feet of water. |
Three earth-core rock-fill dams are made from soil and rock materials obtained from borrow areas within the confines of the project. |

| Lesotho Highlands Water Project | ||
The total water consumption in Lesotho is about 2m³/s, while the total availability is about 150m³/s. |
Orange River flows about 2,000km westwards from the Drakensberg mountain region of Lesotho through South Africa. |
The topography of the region will assist with the project, which will provide revenue for Lesotho and supply the country with hydroelectric power. |
The total cost of the four-phase project is expected to be $8bn. |
LHWP will have five dams and about 200km of tunnels and water transfer works constructed between the two countries. |

| Lower Kihansi Hydropower Dam and Reservoir Project | ||
The Lower Kihansi Hydropower Project contract called for the building of an underground power station cavern which has an initial installed capacity of 180MW in three units and a potential ultimate installation of 300MW in five units. |
The Lower Kihansi hydropower project, located 450km south-west of Dar Es Salaam and 80km south of Iringa in Tanzania, includes the construction of a concrete gravity dam with a height of 25m and a length of 200m, which creates a reservoir with a storage volume of one million m3. |
|
| Nile River Barrage, Naga Hammadi | ||
The Naga Hammadi barrage was completed by the spring of 2008. |
Water levels have been raised by 4m with the completion of the new Naga Hammadi barrage. |
The new Naga Hammadi barrage is located some 3,500m downstream of the existing structure. |
The new barrage is a 320m-long concrete structure erected in a single construction pit. |
Fully operational since Spring 2008, the project is a central feature in the water infrastructure of the Nile Valley. |
The construction of the hydro power station is a significant contribution to the national energy supply and will help to protect the climate. |
The hydropower plant, equipped with four Kaplan turbines, has an installed capacity of 64MW. |

Mortar spreading and feather edge treatment applied to the concrete. The Tannur Dam was the first in the Middle East to be constructed with RCC and used a sloped layer method, never before seen outside of China. |

Sketch-diagram of the sloped layer method. This approach involves building up multiple layers, laid successively to build up one single super-layer sloped at an incline of between 1:10 and 1:20, which maximises structural integrity. |
