Project Overview<\/strong><\/div>\n

Ed\ufb01na Barrage on the Rosetta Branch<\/strong><\/h2>\n

The Ed\ufb01na Barrage is located at kilometre 210.00 on the Rosetta Branch of the Nile. It was constructed in 1948 to replace the earthen embankment that used to be built across the Rosetta Branch after each flood to prevent seawater from entering the river channel and to avoid the risks associated with constructing this embankment.<\/strong><\/p>\n

Following the construction of the High Aswan Dam, the barrage became important for managing excess water, regulating water levels, and supplying the canals branching off upstream while maintaining their required levels. These include the Mahmoudia Canal, the Eastern and Western Rashidiyya Canals, and the Bahr El-Saidi Canal.<\/strong><\/p>\n<\/div>\n
