Protection du localité Ain Ferradja contre les inondations (w. Tissemsilt)

Abstract

The purpose of this study is to protect the town of Ain Ferradja, Tissamssilt against floods caused by the wadi Mellah located in the middle of the village. The study started by the determination of climatic characteristics of the basin, the latter 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 field, we identified anomalies and assess vulnerability and determination of various hydraulic and geometric parameters of flow. According to the results of this diagnosis 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 the project implementation costs.
