    Combination of geophysical and hydrochemical methods for a downstream environmental characterization of El Hadjar Steel industry
    (NATIONAL HIGHER SCHOOL OF TECHNOLOGY AND ENGINEERING - ANNABA, 2024) BELKRAOUANE Nesma Amina; HABES DRICI Sameh (Encadrant)
    The application of geophysical prospecting techniques offers an opportunity to establish a fairly precise diagnosis of the state of the situation downstream of El Hadjar steel industry. The study is conducted by the use of electrical and magnetic prospecting methods as well as the characterization of the physical and chemical properties of rocks and waters in the region. Magnetic prospecting allowed us to determine the magnetic susceptibility of the rock samples and to confirm the presence of trace metal elements in the study area. Physico-chemical analyses of the water in the steel industry's drain channel were carried out in situ to determine the possible pollution generated by this metallurgical industry. The results show significant variations in the properties of the rocks, as well as a real contamination of the water by discharges from the steel industry, subsequently affecting Wadi Meboudja, Wadi Seybouse and finally reaching the Mediterranean Sea. This study highlights the importance of geophysical and hydrochemical techniques for effective environmental management and for minimizing the negative impacts of industrial activities on the environment.

    Proposal for a rehabilitation plan in the context of sustainable development and environmental protection. Case of the quarry of Bentonite of M’Zila
    (NATIONAL HIGHER SCHOOL OF TECHNOLOGY AND ENGINEERING - ANNABA, 2024) BELKRAOUANE Nesma Amina; HABES DRICI Sameh (Encadrant)
    This work focuses on the environmental impacts generated by the extraction of bentonite in the M'Zila region, Mostaganem, with a focus on sustainable rehabilitation measures. Bentonite is a special kind of clay with special characteristics; it is used in many types of industries but its extraction could be ecologically perturbing. The present study evaluates the mining site, analyzes the environmental impacts, and proposes sustainable management strategies for minimizing negative effects. A restoration plan that ensures a focus on revegetation and site rehabilitation to ensure economic gains with reduced environmental impact is proposed. The thesis aims to demonstrate an informed case on how responsible practices in exploitation and restoration can be done so that environmental effects which are fronts within the mining industry might reduce.
