Auteur(s): Layadi, Racha Résumé: Through this modest study, the phenomena of corrosion and scaling in metal pipes buried in the ground have been explained, leading to significant performance losses and sometimes acute technical issues. The study extends beyond a simple theoretical analysis, as it also includes a real-life case study involving the application of cathodic protection on the AEP Ain Azel pipeline to ensure its proper functioning. 2024-01-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/982 Titre: Etude de la qualité physico-chimique des eaux alimentant la ville de Mascara à partir du barrage de Bouhanifia (w.Mascara) Auteur(s): Merine, Fatima Zohra Résumé: The dissertation addresses an issue related to water quality preventing infections caused by water, underscoring the objective of a study on the physic-chemical and bacteriological characteristics of the waters from the Bouhanifia dam, crucial for the water supply of the city of Mascara. To achieve this, analyses were conducted using standard methods over a three- month period, from August to October 2023. The analyses focused on various parameters, including chemical composition, pollution parameters and physical properties. The conclusions drawn from these analyzes indicate that the quality of the treated water complies with Algerian and WHO standards. To conclude this work, we have formulated recommendations aimed at improving the quality of this water. 2024-01-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/980 Titre: Elaboration d’une base de données SIG pour la gestion du réseau d’alimentation en eau potable des POS 15 et 16 de la commune de Berrouaghia (w. Médea). Auteur(s): Messaoudi, Yousra koutr el nada Résumé: This work is part of the problematic of designing a GIS database for the management of drinking water distribution networks. The objective is to create a GIS model using the ArcGIS computer tool to assist the manager in the continuous maintenance of the network and to understand the presented network well. In this context, the area of "POS 15 and 16" in the municipality of Berrouaghia, wilaya of Medea, has been selected as the field of application for this study. The methodology followed for the development of this platform is based on the design of a hydraulic model in a GIS platform. In fact, the created model (database) of the drinking water supply network contains all the necessary data and information in ArcGIS that allow us to develop this model, which can be considered as a decision-making tool in the management of drinking water distribution networks. 2024-01-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/979 Titre: Le processus de la modélisation des débits liquides par le modèle SWAT Auteur(s): Djerboua, Besma Résumé: The modeling of liquid flows focuses primarily on the function of the hydrological cycle at various spatial and temporal scales of a hydrographic basin. The objective of this project is to define the behavioral law of the Macta hydrographic basin regarding hydrological response, using a conceptual model such as SWAT (Soil and Water Assessment Tool). In this part of the research, a literature review of similar studies has been conducted. The input and output variables have been collected and processed. The procedure for integrating these data into the ARCSWAT software, as well as the various simulation steps, has been explained. 2024-01-01T00:00:00Z
