Article Assessment of the Repeatability of Column Experiments Results on the Example of a Conservative Tracer(Sciendo, 2025) Pietrzak, Damian; Kania, Jaroslaw; Kmiecik, Ewa; Baba, AlperMost studies on the behavior of pollutants in the groundwater environment are carried out in laboratories, and the results are then implemented at local and regional levels using model simulations or analytical solutions. Column experiments are used to determine the transport characteristics of inorganic and organic chemicals in the soil and water environment. Although column experiments have been conducted regularly for many years, there is currently no established standard protocol for setting up and conducting them to ensure consistent results. The repeatability of column experiments was evaluated for soils, which differ primarily in the silt and clay content, using a conservative tracer susceptible only to advection and dispersion processes to reduce the number of variables affecting the results of the study which arise in a case of using reactive contaminants. The column experiments performed according to the adopted methodology are characterized by high repeatability of the obtained test results for the transport parameters, regardless of the type of injection or the chosen column length (only a small-scale effect is visible). Based on the results, it can be noticed that for the same soil the values of the pore-water velocity for different types of injections and column lengths are very similar. The percentage difference between the values of pore-water velocity obtained for both tested soils does not exceed 5% and for individual pairs of parallel column experiments it does not exceed 3%.Article Decision-Support Approaches for Sustainable Water Resource Management in Northwest Algeria(Polish Society of Ecological Engineering – PTIE, 2025) Meskine, Ahmed; Cherif, El Amine; Zerouali, Bilel; Ouadja, Abid; Santos, Celso Augusto Guimaraes; Bailek, Nadjem; Baba, AlperThis study investigates water resource management in the Wilaya of Mostaganem, northwest Algeria, using the water evaluation and planning (WEAP) decision support tool in combination with the analytic hierarchy process (AHP). As water scarcity becomes increasingly critical due to population growth, agricultural demands, and climate variability, effective management strategies are essential. This research employs WEAP to simulate various water demand and supply scenarios, assessing the impacts of irrigation efficiency, industrial development, and climate conditions on water availability. Under the ASI scenario, unsatisfied water demand may reach 4.3 hm3 per year by 2027. However, improving irrigation efficiency could reduce this by up to 50% compared to the reference scenario. Seasonal variations reveal deficits reaching 3.2 hm3 per month during the summer months of July through October. Additionally, the study highlights that a significant increase in water demand, exceeding 80 hm3 by 2060, can be mitigated through improved water supply initiatives, such as constructing new dams. The integration of AHP enables the prioritization of management strategies based on stakeholder preferences, demonstrating that adapting to climate change can stabilize demand below 50 million cubic meters. This integrated approach provides valuable insights for policymakers and stakeholders in developing sustainable water resource strategies that address the challenges faced by the Mostaganem region.Book Part Application of Nanofiltration for Reclamation and Reuse of Wastewater and Spent Geothermal Fluid(CRC Press, 2023) Jarma, Yakubu A.; Cihanoğlu, Aydın; Güler, Enver; Tomaszewska, Barbara; Kasztelewicz, Aleksandra; Baba, Alper; Kabay, NalanAfter the extraction of energy from the geothermal fluid, the consumed geothermal water can be considered as a potential water resource for agricultural and industrial purposes. The used geothermal water can also be used as a source of drinking water, which could reduce the pressure on the current clean water resources. On the other hand, geothermal fluids brought to the surface need to be treated in the most economical way before discharge into the surface environment or aquifer. Several processes have shown promising results for the treatment of geothermal water. Membrane processes such as nanofiltration (NF) and reverse osmosis (RO) can be considered as a technology for obtaining good quality irrigation water from geothermal water. This chapter summarizes the application of NF for the recovery and reuse of wastewater and spent geothermal water. © 2024 selection and editorial matter, Abdul Wahab Mohammad, Teow Yeit Haan and Nidal Hidal; individual chapters, the contributors.Conference Object Citation - Scopus: 5High Arsenic Levels in Water Resources Resulting From Alteration Zones: a Case Study From Biga Peninsula, Turkey(Taylor and Francis Ltd., 2010) Baba, Alper[No abstract available]Book Part Citation - WoS: 7Citation - Scopus: 7Application of Geophysical Methods in Gulbahce Geothermal Site, Urla-Izmir, Western Anatolia(Taylor & Francis, 2014) Pamukçu, Oya; Gönenç, Tolga; Sındırgı, Petek; Baba, AlperThe western Anatolian region is considered to be one of the most tectonically active, rapidly deforming, and extending areas in the world (Bozkurt 2001; Dewey and Sengor 1979; Jackson and McKenzie 1984; S¸engör et al. 1985; Seyitog˘lu and Scott 1992) (Fig. 14.1). The region is rich with geothermal potential. Systematic geothermal exploration of the region began in 1960s. Medium-and high-temperature fields in and around Izmir city (Fig. 14.1) have been identified. There are a number of district heating systems, greenhouses, and spa complexes commercially utilizing geothermal energy in the region.
