Etude de protection contre les inondations par Modélisation des affluents Cas : du centre de Bordj Mira (w.Béjaïa)

Abstract

The main objective of this study is to analyze the protection measures needed for the center of Bordj Mira city, capital of Taskriout municipality, against the recurrent flooding of Ait smail and Agrioune tributaries.an approach taken to prevent flooding risks in this city it involves an in-depth analysis of flooding risks, assessment of issues and vulnerability as well as the determination of flood-prone areas; using hydraulic simulation tools such as: Ars GIS, HEC, GEO, and HEC-RAS. Subsequently, a technically and economically viable alternative is rigorously developed, consisting of a gabion channel for the Agrioune river and RIP-RAP for the Ait Smail river. This alternative is chosen from various proposals and development scenarios to enhance the city's resilience against flood risks. This proactive strategy aims to ensure the safety and sustainability of Bordj Mira, thereby making a significant contribution to the sustainable management of flood risks
