Developing a geotechnical microzonation model for Yenişehir (Bursa) settlement area

Kolat, Çağıl
The purpose of this study is to develop a geotechnical microzonation model regarding the suitability of the residential areas in Yenişehir (Bursa, Turkey), which is a currently developing settlement area in a seismically active region. For this purpose, soil properties and dynamic soil behaviors of the study area were assessed. Soil classification, soil amplification, natural soil predominant period, resonance phenomena and liquefaction potential of the study area were evaluated using borehole data and microtremor measurements. The raw data obtained from the previous studies carried out at Yenişehir were used for these assessments. The liquefaction potential for the study area was evaluated both in two-dimensional planimetric and three-dimensional volumetric assessments. Two geotechnical microzonation maps were produced for the study area according to the surface damage due to liquefaction (according to two different methods), soil amplification and distance to streams maps; by using Geographical Information Systems (GIS) based Multi-Criteria Decision Analysis. The weight values were assigned to the layers using Analytical Hierarchical Process method by pairwise comparisons. Evaluating geotechnical microzonation maps produced, the safest areas were found on the northern sites of the study area. The most critical areas were found to be in the middle and the southeast parts of the study area.


Modeling and development of a groundwater management plan for Ulubey aquifer system, Uşak-Turkey
Ünsal Erdemli, Burcu; Yazıcıgil, Hasan; Department of Geological Engineering (2008)
The purpose of this study is the characterization and modeling of Ulubey aquifer system which serves as an important water supply for Uşak province located in inner parts of the Aegean Region in Turkey. In recent years, growing population, accelarating industrial activities and on the contrary decreasing rainfall and contamination of the surface water resources made groundwater indispensable to meet domestic, agricultural and industrial water demands of Uşak province. All these facts necessitate the develop...
Artificial recharge of groundwater in Küçük Menderes River Basin, Turkey
Peksezer, Ayşe; Yazıcıgil, Hasan; Department of Geological Engineering (2010)
Küçük Menderes River Basin located in western Turkey has been facing continuous groundwater level decreases for the past 30 years. In dry periods, irrigation demand is completely met by pumping from groundwater system, which reduces water levels significantly. This provides enough storage to be recharged in wet seasons when streams are running. However, increased runoff in wet season are not utilized neither for irrigation nor for recharge and lost to the Aegean Sea without being infiltrated. Hence, surface...
Landfill site selection and landfill liner design for Ankara
Yal, Gözde Pınar; Akgün, Haluk; Department of Geological Engineering (2010)
The main scope of this thesis is to select alternative landfill sites for Ankara based on the growing trends of Ankara towards the Sincan and Gölbaşı municipalities and to eventually select the best alternative. Landfill site selection was carried out utilizing Geographic Information System (GIS) and Multi-Criteria-Decision-Analysis (MCDA). A number of criteria were gathered in a GIS environment. Each criterion was assigned a weight value by applying the Pairwise Comparison Method (PCM). “The Technique for ...
Post-paleocene deformation in Kalecik region, East of Ankara, Turkey
Kasımoğlu, Pınar; Rojay, Fuat Bora; Department of Geological Engineering (2010)
In order to understand the tectonic evolution of the Kalecik region (Ankara, Turkey), a structural field study was performed in a selected area located in the east of Kalecik, where mostly imbricated thrust sheets of the Cretaceous Ophiolitic melange crop out. In the study area, the Cretaceous Ophiolitic melange, Cretaceous radiolaria-bearing sequences and the Paleocene units are all intruded by sub-vertical dykes. The attitudes of planar structures (dykes, beds and faults) and the kinematic data measured o...
Morphological analyses in Hattusha (Boğazkale-Turkey)
Dündar, Pınar; Toprak, Vedat; Department of Geological Engineering (2009)
The purpose of this study is to investigate the morphological properties of the ancient city Hattusha and its surroundings. To achieve this, the analyses are conducted on the digital topographical maps at 1/25000 and 1/1000 scales. Results of the analyses reveal that Hattusha is located over a north facing surface with slope values of 6 to 15 degrees within an elevation range of 1000 to 1250 m. All main building complexes are confined to a narrow slope interval of 2 to 15 degrees. Five regions are detected ...
