Intensifying industrial, population and agricultural activities have increased the contamination possibility on highly demanded groundwater resources. Bakırçay located at lower North Aegean region of Turkey is one of those basins which has been subjected to such activities. Therefore, aquifers located in the basin are vulnerable. The main purpose of this study is to quantify the contamination vulnerability of the groundwater resources present in the Bakırçay Basin. The DRASTIC methodology which was modified by integrating the land use map of the study area, was applied. The DRASTIC includes hydrogeological factors which control surface infiltration of waters to the aquifer: depth to groundwater (D), net recharge (R), aquifer media (A), soil media (S), topography slope (T), impact of vadose zone media (I), and hydraulic conductivity of the aquifer (C). Available hydrogeological data from various sources for the basin and the data provided from the groundwater flow model established to acquire some parameters due to missing data were utilized to generate groundwater vulnerability map using geographic information system (GIS) tools. The results of this study show that 4.9% of the study area has very high, 20.2% high, 6.2% medium, 24.5% low and the remaining 44.3% of the area has very low contamination vulnerability of the groundwater resources.

Low-energy alinite cement production by using soda waste sludge Uçal, Gültekin Ozan; Tokyay, Mustafa; Department of Civil Engineering (2016) Increased environmental awareness and the concept of sustainable development have impacts on cement industry as on many other fields. Alinite cement which was developed in the 1970s may be an alternative inorganic, low energy binding material. In this study, synthesis and optimization of the properties of alinite cement was carried out by using soda waste sludge as a raw material. Soda waste sludge was mixed with limestone, clay, and iron ore in different proportions. All mixes were burned at 1050oC or 1150...
Exploring the enablers and barriers of circular economy and blockchain adoption in the construction industry Şahin, Ufuk; Atasoy Özcan, Güzide; Department of Civil Engineering (2023-1-26) Due to the take, make, and dispose of principle, which is the result of the linear economy model, massive natural resource exploitation of the construction industry (CI) results in various undesired environmental side effects. The circular economy (CE) concept emerged to alleviate negative impacts and change linear processes with circular ones. In this context, the successful use of CE in the construction industry can significantly contribute to remarkable reductions in gas emissions, massive natural resour...
Comparison of energy consumption and carbon footprint of wastewater treatment systems through modeling Okan, Bora; Ergüder Bayramoğlu, Tuba Hande.; Department of Environmental Engineering (2019) With increasing population and developing regulations, wastewater treatment plants (WWTP) have started to become a higher energy consuming sector in order to serve higher capacities. In the design and management phases of a treatment plant, energy consumption and carbon footprint of the plant should be considered. In this regard, hypothetical and real case models are created to simulate and compare WWTP systems. In this thesis study, first, municipal WWTPs of Turkey were analyzed to determine the traditiona...
Reading Vulnerabilities through Urban Planning History: An Earthquake-Prone City, Adapazarı Case from Turkey ORHAN, Ezgi (Middle East Technical University, Faculty of Architecture, 2016) Agglomeration of urban population, inadequate institutional capacity, unplanned urbanization, dense built environment, and industrial concentration are considered as the main causes of urban vulnerabilities against encountered disturbances. Planning decisions which regulate these factors are expected to make contribution to safer urban and social contexts and resilience of cities. However, in developing countries such as Turkey where disaster management is not an integrated part of urban planning process, p...
Development of the algorithm of SOlAR TURnKEY: solar electricity software for Turkey Karaveli, Abdullah Buğrahan; Akınoğlu, Bülent Gültekin; Soytaş, Uğur; Department of Earth System Science (2018) Together with the increase in population, consumption, environmental threats, social inclusion and poverty eradication needs, natural resource corruption and price, rapid electrification of the world necessitates to meet energy demand in the most efficient, economic, environmental and social way. At this point with the sharp decrease in prices, increase in efficiency and development in technology in addition to environmental friendliness and social inclusiveness, solar electricity has gained importance when...
