Etude de faisabilite d'un barrage en terre Ouled Taoui (w. Aïn Témouchent)

Abstract

This thesis focuses on the detailed assessment of an earth dam project, beginning with an in-depth analysis of the study area. A rigorous hydrological study was conducted to understand local hydrological conditions. The central part of the study involved using Plaxis software for numerical modeling of the dam's behavior under various loads, applying the Mohr-Coulomb model and the cohesion reduction method to calculate the safety factor. The analysis covered static and dynamic scenarios before dam filling, as well as the effects of rising groundwater levels up to optimal filling. Simultaneously, an innovative analysis of satellite images was undertaken, utilizing machine learning techniques with Python to assess potential impacts of climate change on the nearby river. This approach detected and quantified potential variations in watercourses, providing crucial insights for future water resource management and adaptation to environmental changes. By integrating these various geotechnical, hydrological, and satellite imaging analyses, this study provides a robust foundation for sustainable dam design and management, addressing current and future challenges related to climate and environmental changes.
