The Jebel Aulia Dam ( Arabic خزان جبل أولياء, DMG Ḫazzān Ǧabal Auliyāʾ ) is a dam in the White Nile near the city of Jebel Aulia around 40 km above Khartoum in Sudan . It was built between 1933 and 1937 in order to compensate for the periods of low water flow in the Blue Nile with the dammed water . From 2002 to 2005 it was retrofitted to generate electricity with an installed capacity of 30.4 MW.
description
The total of 4,395 m long Jebel-Aulia-Damm consists of a 1630 m long gravity dam with a straight floor plan, which is connected by a 2765 m long earth embankment in the flat area in front of the left bank.
A two-lane road leads over the top of the dam, which narrows in the area of the dam so that there is still enough space for a vehicle and a pedestrian.
In the main fairway there is a lock with a chamber of 67 m × 17 m and a bascule bridge . A fish ladder is built in next to it.
The dam can dam the Nile into a reservoir with a length of around 50 km, a depth of 12 to 13 m and a volume of 3,500 million m³. The discharge is regulated through 50 gates in the dam. The reservoir and its periodically controlled discharge balance the water flow of the Nile during the low water period of the Blue Nile on the one hand, and on the other hand, the damming increases the evaporation loss of the White Nile.
Between 2002 and 2005, the dam was upgraded to generate electricity. For this purpose, 40 of the 50 gates were equipped with groups of two turbines and generators, which, if necessary , can be lifted out of the water by a movable gantry crane running on the top of the wall to allow unhindered drainage. These 80 units have an installed capacity of 30.4 MW.
history
The Jebel Aulia Dam was proposed even before the construction of the old Aswan Dam (built 1898–1902), both as a supply for canal irrigation in Egypt and, to a limited extent, as flood protection.
