Description

Drawings showing elevation and cros-section views of the dam. Completed in 1925, the Sennar Dam was built to improve the supply of water from the Blue Nile for irrigation of cotton plantations in Sudan. The Blue Nile has its headwaters in the highlands of Ethiopia and is subject to large seasonal variations in its flow, producing the seasonal floods for which the Nile is famous.
