The Roseires Dam (Arabic: خزان الروصيرص) is a dam on the Blue Nile at Ad Damazin, just upstream of the town of Er Roseires, in Sudan. It consists of a concrete buttress dam 1 km wide with a maximum height of 68 m, and an earth dam on either side. The earth dam on the eastern bank is 4 km long, and that on the western bank is 8.5 km long. The reservoir has a surface area of about 290 km2.
The dam was completed in 1966, initially for irrigation purposes. A power generation plant, with a maximum capacity of 280 megawatts, was added in 1971.[2][3]
Extension Project
The original maximum height of the dam was 68 m, which increased to 78 m in 2013 and the dam is now 25 km long. The dam contains five 3 m x 5 m low level sluice gates designed to pass floods and sluice sediment. The dam contains a gated ogre spillway with a discharge capacity of 694 m3/s. In addition, the dam was designed with five low level outlets with a discharge capacity of 5,208 m3/s to pass floods and sluice sediment through the reservoir.[4] The extension allowed the reservoir's design capacity to be increased from 3 km3 to 7.4 km3, thereby increasing the flood-control value of the dam.
