Among the coastal districts of mega city Istanbul, Bakirkoy is one of the most critical one with the importance of air and marine transportation and presence of many other coastal facilities and structures that are prone to suffer from marine hazards. In the history, the Sea of Marmara has experienced numerous earthquake and landslide events and associated tsunamis. Therefore, tsunami risk assessment is essential for all coastal districts of Istanbul, including Bakirkoy district. In this study, a further developed methodology for tsunami human vulnerability and risk assessment Metropolitan Tsunami Human Vulnerability Assessment (MeTHuVA) is applied for Bakirkoy district of Istanbul, considering earthquake generated tsunamis. High-resolution tsunami hazard analysis is performed with the integration of coastal inundation computation with tsunami numerical tool NAMI DANCE and tsunami human vulnerability assessment with GIS-based multi-criteria decision analysis methods (MCDA). Using analytical hierarchy process method of MCDA, a hierarchical structure is established, composed of two main elements of tsunami human vulnerability: Vulnerability at Location and Evacuation Resilience. Tsunami risk assessment for Bakirkoy district is calculated by integrating result of hazard and vulnerability assessments with a risk relation that includes a parameter (n), which represents the preparedness and awareness level of the community. Tsunami simulations revealed that the maximum inundation distance is over 350 m on land and water penetrates almost 1700 m along Ayamama stream. Inundation is observed in eleven neighborhoods of Bakirkoy district. In the inundation zone, maximum flow depth is found to be over 5.7 m. The inundated area forms 4.2% of whole Bakirkoy district, and 62 buildings are located in the inundation zone. Hazard, vulnerability and risk assessment results for different neighborhoods of Bakirkoy district are presented and discussed.

Evaluation of tsunami scenarios for western Peloponnese, Greece Yalçıner, Ahmet Cevdet; Dilmen, D. I.; Aytore, B.; Ayca, A.; Insel, I.; Zaytsev, A. (2014-06-01) Tsunami hazard assessment of the eastern part of the Mediterranean Sea is the current interest of the countries having, a coastline in this region. Considering today's increasing population on the coasts and historical tsunamis, it is essential to estimate the probable tsunami risk, which might occur, to be able to mitigate the risk before the actual tsunami event happens. For this purpose, European Union funded project., SEAHELLARC is formed to develop a methodology and tools for seismic and tsunami safety...
Tsunami risk assessment using GIS-based multi criteria decision analysis at Bakirköy, İstanbul Tüfekçi, Duygu; Süzen, Mehmet Lütfi; Yalçıner, Ahmet Cevdet; Department of Geological Engineering (2016) Northern coast of the Sea of Marmara hosts many of coastal facilities. Bakırköy is one of the most critical coastal districts of İstanbul with the importance of air and marine transportation. There are many other coastal facilities and structures in Bakırköy district such as marinas, small scaled craft harbors, water front roads and business centers that are prone to suffer from the marine disasters. In the history, the Sea of Marmara has experienced numerous earthquakes and associated tsunamis. Therefore, ...
High resolution tsunami vulnerability assessment by GISbased multicriteria decision making analysis at Yenikapı İstanbul Çankaya, Zeynep Ceren; Süzen, Mehmet Lütfi; Yalçıner, Ahmet Cevdet; Department of Geological Engineering (2015) İstanbul is a mega city with its various coastal utilities located at the northern coast of the Sea of Marmara. At Yenikapı, there are critical vulnerable coastal utilities, structures and active metropolitan life. Fishery ports, commercial ports, small craft harbors, passenger terminals of intercity maritime transportation, water front commercial and/or recreational structures with residential/commercial areas and public utility areas are some examples of coastal utilization which are vulnerable against ma...
Valuation of environmental improvements in a specially protected marine area: A choice experiment approach in Gocek Bay, Turkey Can, Ozge; Alp, Emre (Elsevier BV, 2012-11-15) Although the Gocek Bay area was declared as a specially protected area by General Directorate of Natural Assets Protection, the region is threatened because of pollution resulting from increased boat tourism and lack of efficient policies. Extensive measures are being planned in order to protect the region. Coastal management requires the use of technical, social political and economic tools to create a comprehensive management strategy. For environmental investments, it is necessary that benefits and the c...
Numerical assessment of tsunami attack on a rubble mound breakwater using OpenFOAM (R) GÜLER, HASAN GÖKHAN; Baykal, Cüneyt; Arikawa, Taro; Yalçıner, Ahmet Cevdet (2018-03-01) A numerical assessment study of tsunami attack on the rubble mound breakwater of Haydarpasa Port, located at the southern entrance of the Istanbul Bosphorus Strait in the Sea of Marmara, Turkey, is carried out in this study using a Volume-Averaged Reynolds-Averaged Navier-Stokes solver, IHFOAM, developed in OpenFOAM (R) environment. The numerical model is calibrated with and validated against the data from solitary wave and tsunami overflow experiments representing tsunami attack. Furthermore, attack of a p...
