This intervention involved the construction of a new 33 km long high-speed railway line, running through a wide level plateau 550 meters above sea level. The line features12 viaducts (total length of 5.4 km) and the Bel Abbès-Sidi Lahcène link that serves as an interchange hub between the new (NLGV Oued Tlelat/Tlemcen) and existing lines.
The hydraulic works designed for this project were developed to resolve potential interferences between the new rail line and the superfi cial hydraulic network, and to defi ne railway platform drainage systems and hydraulic protection works for this important infrastructure. Crossings such as viaducts and bridges feature routing channels and trenches below the structures, with the exception of channels handling larger fl ow rates (Oued Tlelat, Makkerra, Isser). Interferences with hydraulic networks were resolved using 2x2 m underground concrete conduits.
