Ethiopia's rivers carry a high silt content, due to heavy erosion which is accelerated by deforestation and inappropriate agricultural practices on steep mountain slopes. The reservoir of one of Ethiopia's oldest large dams, the Awash dam commissioned in 1966, is close to reaching the end of its useful life due to siltation.
Once completed, the hydroelectric dam will be the second-largest dam in Ethiopia after the Grand Ethiopian Renaissance Dam (GERD) generate up to 6,460 Giga watt-hours (GWh) of electricity, while counterbalancing approximately one million tonnes (Mt) of CO 2 annually. [1] [6] It has 201 meters height and 1012 meters length. On 28 September 2023 ...
In 1989, with the help of Soviet engineers, the Melka Wakena dam was built on the upper reaches of the Shebelle River in the Bale Mountains. Producing 153 megawatts, this dam is Ethiopia’s largest hydroelectric generator. [12] The recent history of the Shabelle is marked by frequent destructive flash floods.
This is a list of streams and rivers in Ethiopia, arranged geographically by drainage basin. There is an alphabetic list at the end of this article.
It will thus increase the useful lifetime of dams in Sudan – such as the Roseires Dam, the Sennar Dam and the Merowe Dam – and of the Aswan High Dam in Egypt. The beneficial and harmful effects of flood control would affect the Sudanese portion of the Blue Nile, just as it would affect the Ethiopian part of the Blue Nile valley downstream ...
The river is not navigable and it has no notable tributaries, but the River basin contains a sizable number of ~97 small rivers and streams in three sub-basins. The average annual discharge at its mouth amounts to 11 m 3 /s, with peak discharges reaching ~40 m 3 /s in spring and autumn, while in summer and winter the discharge can drop to 2-3 m ...
The dam was Ethiopia's largest public works project. [2] The dam helped to reduce power shortages as Ethiopia's power demand increases. At the time of its completion, the 188 metres (617 ft) Tekezé Dam was Africa's largest double-curvature arch dam. [3] The resulting reservoir is 105 km 2 large and it has a capacity of 9.3 billion m 3 of water ...
The dam is 1,700 m (5,600 ft) long and 40 m (130 ft) tall. Construction on the dam began in 1988 but work was halted in 1994. In 1995 construction restarted with a new construction firm. The power station was commissioned in 2004. [2] Water from the dam is diverted through a 9.2 km (5.7 mi) long tunnel to an underground power station downstream.
