USE OF MACHINE LEARNING ALGORITHMS AND IN SITU DATA FOR ESTIMATING PARTICULATE ORGANIC CARBON FROM THE MEDITERRANEAN SEA

Fellous Samir, 
2022-08-22

Résumé: Water quality indicators, including biological, chemical, and physical properties, are usually determined by collecting data from the field and analyzing them in the laboratory. Although these in situ measurements are costly and time-consuming, they offer high accuracy. This study focuses on the estimation of particulate organic carbon (POC) as a water quality parameter using a combination of machine learning algorithms and hyperspectral in situ data. A data-driven approach that does not need any domain knowledge was used. We were interested in POC generated by bacteria, phytoplankton, zooplankton, detritus, and sediments in the Mediterranean Sea from the period of 15 May to 10 June 2017. Therefore, the objective of this study was to use five regression frameworks from machine learning algorithms, to estimate POC with hyperspectral in situ data and evaluate their performance. Based on the coefficient of determination R2 the best-performing modes were nearest neighbors (KNN), Gradient boosting (GB) and random forest (RF) with an R2 in the range of 72.33 to 74.7%. These machine learning models can be used to investigate more water quality parameters, as they reveal a great potential of this approach.

Résumé: Given the importance of water in human life, most communities have developed specific systems to exploit water resources in various aspects of life. From region to region, settlement to settlement, a set of determinant factors have contributed to these systems' creation and development. In this research, we have tried to highlight the particularities of the traditional water management system in the case of the village of Menades. We also tried to identify the transformations (technical, economic and social, etc.) and the development process that have influenced this system over the last forty years to become what it is today. By addressing these aspects, we attempted to identify the current difficulties of water management in the village and their possible solutions. The methodological tools used were observation, interviews, Google Earth Pro software, and microbiological analysis of the water. The results of the research indicate that the system has evolved as a result of a number of exogenous and endogenous factors. This evolution presents some positive aspects, but also a number of challenges and problems to which the various stakeholders need to work together to find appropriate solutions.

DRINKING WATER PROBLEMS IN RURAL AREAS: REVIEW OF POINT-OF-USE METHODS TO IMPROVE WATER QUALITY AND PUBLIC HEALTH

Ihsan Taufiq,  Derosya Vioni, 
2024-04-28

Résumé: Waterborne pathogens from poor sanitation are the main cause of drinking water problems facing humanity in the 21st century, leading to infections and diarrhea. This results in over half a million deaths annually, with most of them occurring in developing countries such as Indonesia. Due to the lack of access to centralized water treatment facilities, point-of-use (POU) systems have been suggested as an important solution for water treatment in developing communities. These systems are user-friendly, low-cost, low-maintenance, and do not depend on the power grid. Importantly, they treat and reduce the number of pathogens in the water supply, and many POU systems have been implemented and used by communities on a household scale. However, the POU system has limitations that hinder its implementation in Indonesia. To examine and evaluate the technology implemented in POU systems, this review focuses on systems that can serve households or communities. The advantages, disadvantages, and limitations of technology that have existed in the last decade are explained. By taking the case of Indonesia, it is hoped that this review can provide an evaluation and illustration of its application in similar developing countries. Another affordable technological solution suggested that could benefit people relying on unsafe water sources

EVALUATING THE EFFECTIVENESS OF THE EXISTING FLOOD RISK PROTECTION MEASURES ALONG WADI DEFFA IN EL-BAYADH CITY

بن سعيد مصباح, 
2024-04-24

Résumé: The main cause of flooding in Algeria often arises from water overflowing from the wadis into nearby urban areas. This situation can become even more critical in the arid regions of Algeria, where a prolonged lack of rainfall has been noticeable in recent decades. This has led to decreased flow in these wadis and, consequently, an increase in human activities encroaching upon the dry areas near the wadis. As a result, this has given rise to exceptionally severe catastrophic events. This paper focuses on El Bayadh city, which is among several cities in the region that have experienced multiple destructive floods, including events in 1991, 1993, 1997, 2004, 2008, 2011, and 2023. However, the most catastrophic flood in El Bayadh city occurred on October 1st, 2011, resulting in the tragic loss of 13 lives and significant material damage. This particular event was numerically reproduced, including hydrological and hydraulic modeling, and subsequently calibrated using observed data. The aim was to assess the performance and capacity of the channel and protective structures in safeguarding the city's nearest buildings. It was demonstrated that the occurrence on October 1, 2011, with a peak discharge of 425 m3/s, greatly exceeded the channel's capacity, which can only handle a peak discharge of 180 m3/s.

Résumé: The main objective of this study was to investigate the mechanism of mеthyl violеt 10B dyе adsorption onto dry sprigs of Spearmint, determine the most suitable kinetic and isothermal models for the adsorption process, and estimate the maximum adsorption capacity for the dye. Experimental results revealed that the optimal adsorption conditions were achieved with an adsorbent mass of 0.01 grams, a pH of 5, and an equilibrium time of 30 minutes. The adsorption capacity of the mеthyl violеt 10B dyе increased with higher initial dye concentrations but decreased as the temperature increased. The pseudo-second-order kinetic model provided the best fit to the experimental data. The Temkin isotherm model demonstrated the best fit, and the maximum adsorption capacity for monolayer adsorption was determined to be 84.83 mg/g. The thermodynamic parameters confirmed that the adsorption process was spontaneous (ΔG°<0), exothermic (ΔH°<0), and exhibited low randomness (ΔS°<0). The adsorbent exhibited promising results, including high mеthyl violеt 10B dyе removal efficiency, low economic cost, and environmental friendliness. These findings suggest that the adsorbent has the potential to serve as a viable alternative for sustainable wastewater treatment

Résumé: Scouring is considered as a major contributor to bridge failure in across the world. The expansion of the scour hole can lead to instability of the bridge structure. Consequently, scour depth prediction is considered a common river engineering practice to take necessary controlling measures. Accordingly, this study investigated the impact of perforated collars of different shapes on scouring around bridge piers. It was found that the scour further decreased as the collar shape was changed from the triangular to the rectangular one. By installing triangular, circular, square, and rectangular perforated collars with the same hole diameter (d/D) of 0.1, maximum scour depth respectively decreased by 35.2, 37.4, 38.4, and 50.9% in comparison with the collar-less bridge pier. Installation of the triangular, circular, square, and rectangular perforated collars with a hole diameter (d/D) of 0.15 reduced scouring respectively by 27.7, 31.6, 33.4, and 45.8% compared to the collar-less pier. Scouring respectively decreased by 16.6, 22.3, 24.7, and 27.6% compared to the collar-less pier by installing the triangular, circular, square, and rectangular perforated collars with a constant hole diameter (d/D) of 0.2. Scouring increased by 29.7% on average at all velocities as the diameter of the collar hole (d/D) increased from 0.1 to 0.2. Furthermore, scouring increased with increasing velocity. Scouring was found to increase by 94.7% on average with a rise from 0.54 to 0.95 of the flow intensity (V/Vc).

Résumé: Nitrogen compounds, including nitrates, are threatening the quality of water in the Continental Terminal aquifer in the Abidjan district. Consumption of nitrate-rich water (over 50 mg/l) can have harmful effects on human health. This study was prompted by the observation that nitrate levels were high in the water from certain boreholes in the Adjamé Nord catchment area, with the aim of reducing nitrate levels in drinking water. To achieve this objective, the water from a borehole was filtered on a weakly basic anionic resin pilot plant to reduce the nitrate content in the drinking water. The variation in the flow rate of raw water passing through the resins was studied to see the effect of the flow rate on nitrate removal. Three flow rates were tested, taking into account the treatment capacity of the pilot plant (200 l/h ; 300 l/h and 800 l/h). The results of the elimination tests show that the resin is effective in denitrating the water. The duration of the cycle varies according to the flow rate (78h for 200l/h ; 46h for 300l/h and 14h for 800l/h). The results of the elimination tests show that the resin is effective in denitrating the water. The duration of the cycle varies according to the flow rate (78h for 200l/h ; 46h for 300l/h and 14h for 800l/h). At the start of each cycle, the raw water nitrate removal rate reaches 95% and decreases over time. Whatever the flow rate of the raw water used, nitrate removal was satisfactory (95.68% for the 200l/h cycle, 90.81% for the 300l/h cycle and 91.08% for the 800l/h cycle).

EXPERIMENTAL ANALYSIS AND PARAMETRIC INVESTIGATION OF WATER ELECTROLYSIS PROCESS FOR HYDROGEN GAS PRODUCTION

Ambaliya Sanjay,  Dhiman Vijay,  Mistry Manish, 
2024-04-28

Résumé: Vehicles and small-scale power generation systems rely on petroleum-based fuels, known as hydrocarbons (HC). When these hydrocarbons burn, they release gases such as CO2, CO, HC, and NOx, which can have adverse effects on both the environment and human health. Hydrogen gas, generated through water electrolysis, offers a promising alternative to hydrocarbon-derived fuels. This article delves into an experimental investigation focused on H2 gas production using water electrolysis. The primary objective is to explore the influence of alkaline electrolytic cell operating parameters on hydrogen gas production, cell efficiency, and power consumption. Stainless steel SS316 serves as the electrode material, while potassium hydroxide (KOH) acts as the aqueous electrolyte solution. Operating parameters such as electrolyte concentration (m), electrolyte temperature (°C), and distance between electrodes (mm) are carefully chosen to analyse their impact on reducing power usage. The Taguchi approach, facilitated by MINITAB software, is employed for experiment design selection, with the Signal-to-Noise (S/N) ratio guiding the determination of the optimal operating parameters. Through ANOVA (analysis of variance), the individual contribution of each operating parameter to power utilization is assessed. A regression equation is formulated to predict hydrogen production rate, cell efficiency, and power consumption. Experimental data is compared with predicted values to validate the regression equation's accuracy.

KINETIC AND ISOTHERM STUDY OF METHYLENE BLUE ADSORPTION ON ORANGE PEEL ACTIVATED CARBON

هندة خليلي,  Achour Samia,  Konan Gervais Kouame,  Guellal Messaoud, 
2024-04-28

Résumé: The aim of this work is to use activated carbon derived from orange peel to remove methylene blue from water. The adsorption of this dye was carried out in batch mode and the analysis of the methylene blue solution samples was carried out on a Shimadzu UV-visible spectrometer. The mass of carbon, the initial concentration of the dye solution, as well as kinetic models, isotherm models and thermodynamic studies were studied. Analysis of the adsorption data showed that the optimum dose of activated carbon was 300 mg/L for an 90.84 % adsorption rate. The concentrations used to study the influence of concentration proved to be too low to achieve saturation of the adsorbent. Modelling of the kinetics showed that the methylene blue adsorption kinetics followed the pseudo-first-order kinetic model. Isotherm modelling revealed that methylene blue adsorption follows the Freundlich-Langmuir model. The values of the thermodynamic parameters show a spontaneous and exothermic phenomenon.

Résumé: Quetta is an important urban center and capital of the Balochistan province of Pakistan. Due to its arid climate and absence of reliable surface water resources, the city heavily relies on groundwater, where rainfall is the prominent source of recharge. As per the past studies, due to increased population and unregulated extraction, groundwater level in Quetta is declining at a rate of 1.5-5 m/year, which calls for a detailed assessment of its recharge regime for a sustainable resource protection. Therefore, the monthly and annual groundwater recharge in Quetta from rainfall was computed in this research using the water balance approach for the period 1990-2023. The analysis showed a significant reliance of groundwater recharge on the climate patterns, with the highest monthly recharge in January (21.6 mm) due to high rainfall and low ET, while lowest recharge was found in July (3.31 mm) due to low rainfall and high ET losses, with the mean annual total recharge as 108.6 mm. Further, the Recharge to Precipitation ratio estimated from the daily water balance showed that 15% of annual rainfall contributes to groundwater recharge in Quetta. By evaluating the daily water balance, the study comprehensively explained the monthly and annual groundwater recharge regime, along with the rainfall and ET patterns in Quetta. The outcomes of this research would essentially serve to formulate an effective policy and strategy to optimize the groundwater extraction in Quetta without encroaching the aquifer’s safe yield and to sustainably manage the available groundwater resources for the coming years.
