Application d'un modèle " pluie-débit" dans le dimensionnement d'un évacuateur de crue : cas du barrage de Boukerdane (w. Tipaza)

Abstract

The need for the determination of discharge on ungauged sites corresponds always to the operational concerns: in many design dams projects, it does not have a hydrometric station and recording discharge to assess flood project. The design of dams becomes subject of uncertainties related to approximation methods. The present work aime to determine the spillway size of the dam already exists. The aim is to verify the ability of the spillway Boukerdan to evacuate the design discharge without disturbing the downstream housing and human activities. To do this, it was necessary to define all the methods applicable in the context of an ungauged basin and rehabilitate a more appropriate approach for our watershed. This allowed us to identify the discharge design and propose the most appropriate variant of the spillway in our dam.
