Turkish coastlines have been exposed to devastating tsunamis in the past. Today, Turkey has densely populated shorelines with substantial touristic activities and critical infrastructures along its shorelines. Tsunami propagation database and tsunami forecast models for the coastal communities are the two major components of the tsunami forecasting methodology which is developed by the United States National Oceanic and Atmospheric Administration Center for Tsunami Research (NCTR) at the Pacifi c Marine Environmental Laboratory, Seattle, Washington. Tsunami forecast models take input from the propagation database and estimate coastal fl ooding through three nested grids in real-time. This approach expedites substantially the time required for tsunami forecast for the target shorelines. Thus, following the NCTR's approach, a tsunami propagation database has been previously developed in the Aegean Sea and the Eastern Mediterranean to help capacity building in both long-term (such as inundation mapping) and short-term (real-time) tsunami forecasting capabilities in the region. Here, modeling grids are developed for the town of Fethiye, Muğla, Turkey using publicly available bathymetric and topographic data. Then, forecast model has been developed for Fethiye using the Community Modeling Interface for Tsunamis (ComMIT), which is an interface to the validated and verifi ed tsunami numerical model of the Method of Splitting Tsunami (MOST) and the propagation database. The Fethiye forecast model has been tested extensively, and it shows stability. However, results of the forecast model need to be compared with the model results based on high resolution bathymetric and topographic data. This would be the only way to verify the accuracy of the model which is developed here.

Pedestrian Tsunami Evacuation Time Maps for Southern Coast of Bodrum Peninsula, Turkey Çelikbaş, Büşra; Tüfekçi Enginar, Duygu; Doğan, Gözde Güney; Süzen, Mehmet Lütfi; Kolat, Çağıl; Yalçıner, Ahmet Cevdet; Necmioğlu, Öcal; Annunziato, Alessandro; Santını, Marzıa; Bali, Siret (2020-05-06) Turkey suffered from devastating earthquakes and faced with a considerable number of tsunamis in its past. Although, tsunamis occurred in Turkey are not catastrophic as the ones in Pacific Ocean, they may still cause substantial damage in highly populated and/or touristic coastal areas. On July 21, 2017 at 22.31 UTC, a strong earthquake in the Gulf of Gokova (Mediterranean Sea) with a magnitude (Mw) of 6.6 (KOERI) was recorded. The earthquake caused a tsunami that affected the southern coast of Bodrum, Turk...
Risk Assessment and Design of Prevention Structures for Enhanced Tsunami Disaster Resilience (RAPSODI)/Euro-Japan Collaboration Harbitz, C. B.; Nakamura, Y.; Arikawa, T.; Baykal, Cüneyt; Dogan, G. G.; Frauenfelder, R.; Glimsdal, S.; GÜLER, HASAN GÖKHAN; Issler, D.; Kaiser, G.; Kanoğlu, Utku; KISACIK, DOĞAN; Kortenhaus, A.; Lovholt, F.; Maruyama, Y.; Sassa, S.; Sharghivand, N.; Strusinska-Correia, A.; Özyurt Tarakcıoğlu, Gülizar; Yalçıner, Ahmet Cevdet (2016-12-01) The 2011 Tohoku event showed the massive destruction potential of tsunamis. The Euro-Japan "Risk assessment and design of prevention structures for enhanced tsunami disaster resilience (RAPSODI)" project aimed at using data from the event to evaluate tsunami mitigation strategies and to validate a framework for a quantitative tsunami mortality risk analysis. Coastal structures and mitigation strategies against tsunamis in Europe and Japan are compared. Failure mechanisms of coastal protection structures exp...
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, ...
Flood forecasting and analysis within the Ulus Basin, Turkey, using geographic information systems Usul, Nurunnisa; Turan, Burak (Springer Science and Business Media LLC, 2006-10-01) Floods have been the most severe natural disasters in the West Black Sea Region of Turkey for many years; therefore Ulus Basin is selected as a study area for a thorough hydrologic flood analysis. The lack of embankments around the Ulus River and careless changes to the riverbed made by villagers, resulted in major flood events in the basin, causing significant damage in the area. In this study, the hydrodynamic characteristics of the basin and the riverbed are determined by calibrating the hydraulic module...
Rainfall triggered landslides in unsaturated soils a numerical sensitivity analysis for rainfall threshold Ahmadiadli, Mohammad; Huvaj Sarıhan, Nejan; Toker, Nabi Kartal (2012-04-27) Catastrophic precipitation-induced landslides have frequently hit villages, towns and roads in Black Sea Region in northern Turkey, causing extensive damage and many fatalities. Due to global climatic changes, the intensity and frequency of extreme rainfall events are expected to increase. In addition, due to limited available land on level ground, urbanization continue to increase on sloping ground which increases the exposure and elements at risk. Most available methods for predicting rainfall-induced slo...
