Wider awareness, proper preparedness and effective mitigation strategies need better understanding of tsunamis and tsunami hazard assessment. Tsunami assessment study covers the exchange and enhancement of available earthquake and tsunami data, development of bathymetric and topographic data in sufficient resolution, selection of possible or credible tsunami scenarios, selection and application of the valid and verified numerical tools for tsunami generation, propagation, coastal amplification, inundation and visualization. From this point of view, this thesis deals with all these components of tsunami hazards assessment. The database of 38 different seismic sources is generated and applied to Eastern Mediterranean Basin by using numerical code called NAMI DANCE. Furthermore, the simulation results are compared and discussed. In the thesis, the difficulties in defining seismic source parameters, the effect of dip and rake (slip) angle on seismic generated tsunamis are evaluated. Moreover, the performance of the numerical code, the accuracy of results, the efficiency of the numerical methods in the application to Mediterranean Basin Tsunamis and the comparisons of simulations in nested domains for Bodrum, Kas and Iskenderun are given as case studies. According to the study, north-west and south-west of Turkey may have tsunami risk more than other regions. The maximum wave amplitudes, which may be expected to occur near the shore, are found more than 4 m. However, maximum positive wave amplitude observed in history is approximately 8 m. The arrival time of first wave to hit the coasts vary in a range of 15 to 60 minutes depending on the closeness of the location to the sources’ epicenter.

Assessment of tsunami resilience of ports by high resolution numerical modeling: a case study for Haydarpasa port in the sea of Marmara Aytöre, Betül; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2015) Assessment of tsunami resilience is used to determine proper mitigation strategies. Thus, it is essential to obtain modeling results in highest confidence and accuracy. Haydarpasa Port in the Sea of Marmara is selected for tsunami assessment study due to vulnerable nature of ports against marine related disasters. The region also tends to have tsunamis since it is located on the western part of the North Anatolian Fault zone where 35 tsunamis occurred in last 2000 years. The aim of this study is assessment ...
Advanced two- and three-dimensional tsunami models: benchmarking and validation Velioğlu, Deniz; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2017) Field observations provide valuable data regarding the nearshore tsunami impact, yet only in inundation areas where tsunami waves have already flooded. Therefore, tsunami modeling is essential in order to understand tsunami behavior and prepare for tsunami inundation. Analytical and numerical methods are widely applied to predict tsunami motion and inundation characteristics. On the other hand, the data obtained from field surveys and laboratory experiments are generally used for validation and performance ...
Assessment of inland tsunami parameters and their effects on morphology / Pamuk, Aykut; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2014) Recent tsunami events clearly showed the potential of massive destruction on buildings, infrastructure, coastal protection structures and also morphological changes by tsunami waves. This thesis covers investigation of tsunami motion at inundation zone considering different factors (smoothed ground without buildings, or with buildings), and related changes of inland tsunami parameters and their effects on morphology. For the applications, the simulations have been performed using different topographic condi...
Database development for tsunami information system / Özdemir, Koray Kaan; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2014) Tsunamis are believed to be one of the natural enemies of human kind and evolution as the damage it gives at the shores can be described as lethal in means of loss of lives, tangible damage to the economy and concrete living on the shore, threat to health in variety of sicknesses after drawdown of water. Since this phenomena has been lethal lately even in a country like Japan which was prepared for any fatal earthquakes and tsunamis, it is in great importance to use the technology and history in accordance ...
Tsunami hazard analysis for Güllük Bay Acar, Sena; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2015) The deterministic and probabilistic tsunami hazard analysis is one of the primary issues for disaster management and the determination mitigation strategies. Güllük bay (Turkey) located in southern Aegean Sea is selected as the study region to evaluate the effects of probable tsunami waves in the region. The critical structures in Güllük bay are aquaculture facilities, commercial port, marinas, airport and small size waterfront structures at touristic centers. The seismic and non-seismic sources are process...
