Investigation of the aquifer vulnerability in the Bakırçay basin, Turkey

2022-2
Atasu, Merve
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.

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...
Mining fungal effector candidates in biotrophic plant pathogens : rusts and mildews
Umu, Sinan Uğur; Akkaya, Mahinur S.; Can, Tolga; Department of Bioinformatics (2012)
Biotrophic plant pathogens lead to huge crop losses and they have great economical drawbacks on wheat and barley production. These pathogens rely on formation of haustoria and transfer of effector proteins into the host cells for generating disease. The main role of effector proteins is to disable plant defense mechanisms. Effector proteins contain N-terminal signal peptides and they have little sequence similarity between each other. It is vital to detect as many effector proteins as possible to understand...
Development of fluorescent whole-cell bacterial bioreporters for detection of inorganic arsenic and cadmium
Elçin, Evrim; Öktem, Hüseyin Avni; Department of Biotechnology (2019)
Environmental heavy metal contamination in many regions of the world is a serious problem of ecological health. Fast and constant monitoring of their levels is significant for both preventing their accumulation and taking an immediate action for removal. As an alternative approach to standard laboratory techniques, various biosensor systems for detection of heavy metals have been proposed. Bacterial biosensors hold great promise for in-field detection of heavy metals. In this study, two different whole cell...
