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 of tsunami resilience of Haydarpasa Port with high resolution models according to most effective submarine earthquake as well as to discuss possible effects of increasing data (actual) and model (numerical) resolution to high level and including existing structures specifically as elevation data. Various numerical computations are performed with tsunami simulation and visualization code NAMI DANCE for this purpose. The breakwaters are very important for the resilience of Haydarpasa Port. Main requirement to enhance its resilience is to strengthen the breakwaters. Thus, less amplification inside the port and less inundation of port environs can be obtained and port operations can be continued. Otherwise, such a tsunami will negatively affect this urbanized area by considering economic and social aspects. The highest model and data resolution lead to most accurate results in tsunami modeling studies. However, resolution of available data is more effective on calculated results in comparison with model resolution. Thus, it is possible to determine a proper model resolution according to needs providing that data resolution is sufficient.

Assessment of seismic hazard in the Erzincan (Turkey) region: construction of local velocity models and evaluation of potential ground motions Askan Gündoğan, Ayşegül; Karim Zadeh Naghshineh, Shaghayegh; Sisman, Fatma Nurten; Erkmen, Cenk (2015-01-01) The fundamental step in estimation of seismic damage and losses in urban areas is identification of regional potential seismic hazard. The accuracy of seismic analyses depends on the reliability of the local input parameters used in the corresponding hazard and loss models. This paper presents detailed seismic hazard analyses for an earthquake-prone region using locally derived source and site parameters. Main components of this study are construction of local seismic velocity models, probabilistic and dete...
Database development for tsunami warning system in mediterranean basin by tsunami modeling Onat, Yaprak; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2011) 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 a...
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...
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 ...
Prediction of potential seismic damage using classification and regression trees: a case study on earthquake damage databases from Turkey Yerlikaya-Ozkurt, Fatma; Askan Gündoğan, Ayşegül (Springer Science and Business Media LLC, 2020-09-01) Seismic damage estimation is an important key ingredient of seismic loss modeling, risk mitigation and disaster management. It is a problem involving inherent uncertainties and complexities. Thus, it is important to employ robust approaches which will handle the problem accurately. In this study, classification and regression tree approach is applied on damage data sets collected from reinforced concrete frame buildings after major previous earthquakes in Turkey. Four damage states ranging from None to Seve...
