Etude d'un aménagement de protection contre les inondations cas : de la ville de Sougueur (w. Tiaret)

Abstract

The wadi of Sougueur is the main tributary crossing the town of Sougueur, city of Tiaret. In addition, it contains several other tributaries ranging from medium to large. These rivers are a source of flooding caused by the annual heavy rains that characterize the region. The objective of our study is to estimate the flood water level for each river by adopting the SCS-CN method by the HEC-HMS program, to study natural watercourses reaction, to produce the floodplain map by the using the following softwares: HEC-RAS, Hec GEO-RAS, ArcGIS in order to study the variants proposed on the technical-economy scale for each section and to choose the most appropriate solutions, technically, economically and aesthetically. Finally, a stability study is carried out for the variants selected by the GeoStudio program and the cost and time required to complete this project are determined.
