One of the serious and growing potential problems in most large urban areas is the shortage of land for waste disposal. Although there are some efforts to reduce and recover the waste, disposal in landfills is still the most common method for waste destination. An inappropriate landfill site may have negative environmental, economic and ecological impacts. Therefore, it should be selected carefully by considering both regulations and constraints on other sources. In this study, candidate sites for an appropriate landfill area in the vicinity of Ankara are determined by using the integration of Geographic Information Systems and Multicriteria Decision Analysis. For this purpose, sixteen input map layers including topography, settlements (urban centers and villages), roads (Highway E90 and village roads), railways, airport, wetlands, infrastructures (pipelines and power lines), slope, geology, land use, floodplains, aquifers and surface water are prepared and two different MCDA methods (Simple Additive Weighting and Analytic Hierarchy Process) are implemented in GIS environment. Comparison of the maps produced by these two different methods shows that both methods yield conformable results. Field checks also confirm that the candidate sites agree well with the selected criteria.

Landfill site selection by using geographic information systems Şener, Başak; Süzen, Mehmet Lütfi; Doyuran, Vedat (Springer Science and Business Media LLC, 2005-11-22) One of the serious and growing potential problems in most large urban areas is the shortage of land for waste disposal. Although there are some efforts to reduce and recover the waste, disposal in landfills is still the most common method for waste destination. An inappropriate landfill site may have negative environmental, economic and ecological impacts.

GIS based assessment of excavation difficulty by TBM-EPB along Mecidiye - Tandoğan segment of the Tandoğan - Keçiören metro tunnel Özbaş, Bengi; Doyuran, Vedat; Department of Geological Engineering (2007) Tunnel structures are important investments especially for urban areas. Keçiören - Tandoğan metro alignment is one of those investments executed by Ankara Metropolitan Municipality. The purpose of this research is to evaluate Tunnel Boring Machine (Earth Pressure Balance type) (TBM-EPB) performance within different lithological units encountered along Tandoğan -Mecidiye segment of the Keçiören - Tandoğan metro tunnel. The evaluation is based on the data obtained from traditional site investigation methods, ...
Optimal storage of freshwater in saline aquifers Küstü, M. Deniz; Yazıcıgil, Hasan; Department of Geological Engineering (2005) Storage of freshwater in saline aquifers has a strategic importance in water deficit countries. The freshwater stored in these aquifers may be the only source of water available during times of crisis. Coupled simulation and optimization type groundwater management models have been developed that will achieve the optimal control of the storage of freshwater in a stagnant manner for constant density and variable density flows in hypothetical single- and multi-layered saline aquifers. The study is carried out...
Stabilization of Expansive Soils by Using Aggregate Waste, Rock Powder and Lime Yeşilbaş, Gülşah; Çokça, Erdal; Department of Civil Engineering (2004) Expansive soils are a worldwide problem that poses several challenges for civil engineers. Such soils swell when given an access to water and shrink when they dry out. The most common and economical method for stabilizing these soils is using admixtures that prevent volume changes. In this study the effect of using rock powder and aggregate waste with lime in reducing the swelling potential is examined. The expansive soil used in this study is prepared in the laboratory by mixturing kaolinite and bentonite....
Landfill site selection and landfill liner design for Ankara, Turkey Yal, Gozde Pinar; Akgün, Haluk (Springer Science and Business Media LLC, 2013-11-01) Considering the high population growth rate of Ankara, it is inevitable that landfill(s) will be required in the area in the near future to sustain the sanitary waste disposal needs of the city. The main scope of this study is to select alternative landfill sites for Ankara based on the growing trends of Ankara toward the northwest, particularly toward the Sincan municipality, and to eventually select the best alternative through utilizing multi-criteria decision making. Landfill site selection was carried ...
