Protection de la ville de Bordj Menaiel contre les inondations (w. Boumerdes)

Abstract

The purpose of this study is to protect the town of Bordj Menaiel Boumerdes against floods caused by river flooding Menaiel and Besbes located in the east and west of the city respectively. The study started by the determination of climatic characteristics and and those of the basin, which are essential for a hydrological study, which aims to predict the rainfall of the project. Then we proceeded to the transformation of net rain to flow to determine the central flood flow. The diagnosis of the terrain, and simulating hydraulic operation to the natural state of watersheds, we identified anomalies and assess vulnerability and determination of various hydraulic and geometric parameters of flow. According to the manual of this diagnostic we propose technical and economical solutions in order to retain the best and most adequate. Finally the variant adopted is discussed in detail with the determination of cost and period of project implementation
