Etude du comportement de l'évacuateur de crue du barrage de Barek : utilisation d'une approche déterministe pour l'estimation

Abstract

The need for the determination of discharge on ungauged sites to 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 aims to use a deterministic approach to determine the design discharge of the spillway of the BAREK dam on Zerouala Wadi (Blida Wilaya). To do this, it was necessary to define all the parameters, geomorphologic and climatic of the basin and dams watershed, followed by a geotechnical and hydrological study of the dam site. This has identified the discharge design. Two variants of the spillway were studied at the end the cheapest variant was chosen.
