Etude des variantes de l'evacuateur de crues du barrage de Azib Timizar (w. Bejaia)

Abstract

The objectif of this work is to study different variants of the spillway adequates to allow the floods passage through the AzibTimizar dam on the Flidoun River (Béjaia), by controlling the maximum level reached by the dam and to assure the safety of the properties and people living in the downstream. The work aims to define all the parameters, geomorphologic and climatic of the Flidoun watershed, followed by a hydrological study of the dam site. This study has identified the discharge of design. Three variants of the spillway were studied at the end, and the most adequate variant was chosen. Finally a civil engineering study of the seleted variant was made.
