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.Article Citation - WoS: 6Citation - Scopus: 8The Potential, Utilization and Development of Geothermal Energy in Türkiye(Maden Tetkik ve Arama Genel Mudurlugu-mta, 2023) Sener, Mehmet Furkan; Uzelli, Taygun; Akkus, Ibrahim; Mertoglu, Orhan; Baba, AlperGeothermal energy is a natural resource that can be utilized directly or by converting to other types of energy. Considering the diversity of the geological structure of Turkiye, the geothermal systems have developed depending on young tectonic and volcanic active rock. Western and Central Anatolia are especially rich in geothermal resources. The geothermal well with the hottest well-bottom temperature was drilled in Central Anatolia, and the well-bottom temperature was measured as 341 degrees C at a depth of 3845 meters. In 2022, Turkiye's electricity generation capacity and the total installed direct heat use reached 1663 MWe and 5113 MWt, respectively. Considering Anatolia's Curie depth and heat flux, the probable thickness of the batholith can be regarded as 10 km. For example, the total granitoid area of Western Anatolia is 4221 km2 and at least 2% of this granitoid can provide approximately 8x107 MWh of electricity by Enhanced Deep Geothermal Systems (EDGS). When all granites in Turkiye are considered, it is expected that the future capacity of Turkiye will be much higher with drilling research and development studies and the discovery of new fields. This capacity will exceed 100.000 MWt levels in the medium term, especially with the addition of EDGSs.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.Review Citation - WoS: 14Citation - Scopus: 25Sustainability of Water, Sanitation, and Hygiene: From Prehistoric Times To the Present Times and the Future(MDPI, 2023) Angelakis, Andreas N.; Capodaglio, Andrea G.; Passchier, Cees W.; Valipour, Mohammad; Krasilnikoff, Jens; Tzanakakis, Vasileios A.; Suermelihindi, Guel; Baba, AlperContaminated water and poor sanitation are associated with disease transmission. Absent, inadequate, or improperly managed water resources and sanitation systems expose individuals to preventable health risks. Billions of people lack access to these basic services today and will remain in this condition for decades to come. As we are usually thinking and talking about water, sanitation and hygiene services have changed. Looking back at the history of water, sanitation, and hygiene can help us understand the challenges and opportunities of these issues and draw lessons to achieve sustainable development in the future. Throughout history, civilizations have successfully experimented with treating water and using it for drinking, sanitation, and agriculture. For example, the Minoan civilizations originally focused on water treatment and cleaning to improve the aesthetic properties of drinking water. During prehistoric times, Minoan and Indus Valley civilizations, dating back to about 2000 BC, were the first to focus on the treatment of water supplies. From the early Minoan period, they relied on rainwater collection. During historic times, Hippocrates was the first to invent and used a water filter in the form of a cloth bag, at about 400 BC, known today as the Hippocrates Sleeve. The Romans perfected existing water technologies on a larger scale and initiated their spread throughout the Empire. Hygiene in ancient Rome was promoted by the famous public baths and toilets, which were supplied with water through widely branched aqueducts that had a high standard of cleanliness for the time and were regularly maintained.Review Citation - WoS: 25Citation - Scopus: 35Evolution of Floods: From Ancient Times To the Present Times (ca 7600 Bc To the Present) and the Future(MDPI, 2023) Angelakis, Andreas N.; Capodaglio, Andrea G.; Valipour, Mohammad; Krasilnikoff, Jens; Ahmed, Abdelkader T.; Mandi, Laila; Tzanakakis, Vasileios A.; Kumar, Rohitashw; Min, Zhang; Han, Mooyoung; Bashiru, Turay; Derkas, Nicholas; Baba, Alper; Bilgiç, EsraFloods are one of the most dangerous natural disasters, causing great destruction, damage, and even fatalities worldwide. Flooding is the phenomenon of a sudden increase or even slow increase in the volume of water in a river or stream bed as the result of several possible factors: heavy or very long precipitation, melting snowpack, strong winds over the water, unusually high tides, tsunamis, or the failure of dams, gages, detention basins, or other structures that hold back water. To gain a better understanding of flooding, it is necessary to examine evidence, search for ancient wisdom, and compare flood-management practices in different regions in a chronological perspective. This study reviews flood events caused by rising sea levels and erratic weather from ancient times to the present. In addition, this review contemplates concerns about future flood challenges and possible countermeasures. Thus, it presents a catalogue of past examples in order to present a point of departure for the study of ancient floods and to learn lessons for preparation for future flood incidents including heavy rainfalls, particularly in urbanized areas. The study results show that ancient societies developed multifaceted technologies to cope with floods and many of them are still usable now and may even represent solutions and measures to counter the changing and increasingly more erratic weather of the present.
