Item Analyse fréquentielle et modélisation statistique des crues cas du bassin versant « Isser Sekkak »(2026) Belhadef Chahrazed; Bouazza Chaimaa; Bentahar KheiraFloods are one of the most significant hydrological phenomena due to their impacts on populations, infrastructure, and the environment. The knowledge of extreme flows is essential for the design of hydraulic structures and the management of flood risk. In this context, this work focuses on the frequency analysis and statistical modeling of floods in the Isser Sikkak watershed based on the available hydrometric data. The study consisted of analyzing a series of daily maximum rainfall to evaluate its statistical characteristics and quality. Several probability distributions were fitted to the observed data, including the Gumbel distribution and the log-normal distribution. The quality of the fit was evaluated using the AIC and BIC criteria as well as the Chi-squared and Kolmogorov-Smirnov statistical tests, using the Hyfran Plus and Hydrognomon software. The results obtained allowed for the identification of the most appropriate probability law to represent the behavior of the rainfall in the studied basin. Subsequently, the analysis of short- duration precipitation allowed for the construction of the IDF curves. The interpretation of the results shows that the Sokolovsky method is the most appropriate for estimating the maximum flows of the Oued Isser sikkak basin corresponding to different return periods, such as 10, 20, 50, and 100 years. These estimates provide essential information for the design of hydraulic structures and the assessment of flood risk. Finally, this study highlights the value of frequency analysis as a decision-making tool in the field of hydrology. The results obtained could be utilized in future work on hydraulic modeling and flood zone mapping.Item Etude expérimentale et optimisation des performances du procédé d’osmose Inverse pour le dessalement d’eau de mer(2026) Chelhaoui abdelmoudjib.; Azza mohamed; NEHARI ABDERRAHMANEThe growing demand for freshwater, combined with climate change and the depletion of conventional water resources, has made seawater desalination an essential solution for ensuring water security. Among the available desalination technologies, reverse osmosis (RO) has emerged as the most efficient and widely adopted process due to its high salt rejection, relatively low energy consumption, and economic feasibility. The présent study focuses on the experimental evaluation of a reverse osmosis desalination system using a laboratory-scale pilot unit. A comprehensive bibliographic review was first conducted to present the principles of seawater desalination, the different desalination technologies, membrane characteristics, operating parameters, membrane fouling mechanisms, recent technological developments, and the status of desalination in Algeria, with particular emphasis on the Béni Saf desalination plant. The expérimental investigation aimed to asses the influence of transmembrane pressure and operating time on the performance of the reverse osmosis process. The system performance was evaluated through permeate production and membrane behavior under different operating conditions. The obtained results showed that increasing the operating pressure improves permeate flux and desalination efficiency, while prolonged operation may reduce membrane performance because of fouling and concentration polarization. This work highlights the importance of optimizing operating conditions to improve the efficiency, productivity, and sustainability of reverse osmosis desalination systems. The findings contribute to a better understanding of membrane-based desalination processes and provide useful guidance for improving the performance of seawater desalination technologies.Item dimensionnement d'un réseau anti incendie au Niveau DU SIÈGE LQS ORAN (SONATRACH)(2026) Belgour Nerjesse; Rahmani Asmaa Chahrazed; Nehari Abderrahmane; Ababou HabibFire protection networks are essential components of building and industrial facility safety.

The diagnosis of the existing network, managed by the Algérienne des Eaux (ADE), revealed an aging infrastructure (70% degraded PVC pipes) with an alarming physical water loss rate of approximately 20%. The main objective of this work is to design a high-performance network capable of satisfying long-term water demands up to the 2054 horizon. The methodology first involved demographic forecasting using the geometric growth model, predicting a population of 13,400 inhabitants by 2054, which corresponds to a peak hourly demand of 60.04 L/s. Subsequently, EPANET software was used to simulate and model the hydraulic behavior of the projected network, which consists of 10,916.12 meters of HDPE (PN16) pipelines. The steady-state simulation results validated the network's conformity, showing regulatory node pressures (ranging from 21.31 to 58.36 mH2O) and controlled flow velocities (between 0.30 and 2.00 m/s), thus preventing water stagnation and excessive head losses. Finally, the economic study estimated the total cost of the modernization works (earthworks, pipes, valves, manholes, and household connections) at 56,937,364.93 DZD (including taxes). This project delivers a sustainable technical and economic solution to optimize water resource management and secure the water supply for the population of Belarbi.Item Analyse des répercussions des crues sur le regime de fonctionnement et l'efficacité du procédé de dessalement au niveau de la station BWC(2026) Ammar Amina; Aouabdi Chifa; NEHARI AbdelhadiThis study examines the impact of flooding on the operation of the seawater desalination plant (BWC) by monitoring the effects of heavy flows from Wadi El-Hallouf on the quality of the water supplied to the plant.

It then explores techniques for collecting topographic, geological, climatic, and hydrological data, with a focus on the role of Geographic Information Systems (GIS). Furthermore, the research investigates digital modeling tools such as MODFLOW and GMS, as well as 3D visualization techniques, through the analysis of interpolation methods, layer representation, and interactive modeling. Ultimately, the work proposes a comprehensive scientific methodology for accurately representing aquifer layers, with the objective of supporting decision- making in the management of groundwater resources.Item Investigation of Factors Influencing NOx Emissions in Gas Turbine Generators of a Natural Gas Liquefaction Facility(2025) ELMEZOUAR, Abdel Rafik; ABDALLAH BERRABEH, Ben ali; DR.CHOUAT NadjatThis thesis presents an experimental investigation into the factors influencing nitrogen oxide (NOx) emissions from Frame 6 gas turbines equipped with Dry Low NOx (DLN) systems within a natural gas liquefaction complex. These pollutants represent a major challenge for the energy industry, as their emissions can exceed regulatory limits even with advanced control technologies in place. The study combines a theoretical review of NOx formation mechanisms with a rigorous experimental campaign, utilizing in-situ gas analysis, fuel gas chromatography, and real-time operational data collection. The results demonstrate that fuel gas density and composition, particularly the levels of nitrogen and ethane, have a more decisive influence on NOx production than the fuel's overall calorific value. These findings underscore the need for a systemic, multi-parameter approach to emissions control and open pathways for developing advanced predictive models to optimize the environmental performance of industrial gas turbines.Item Analyse expérimentale et optimisation des systèmes de dessalement solaire pour une production durable d’eau(2025) GHORZI, Redouane; Dr. MILOUD ABID OussamaWater has become a critical global challenge, closely tied to human development, while the search for sustainable sources grows increasingly urgent.
