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 potential tsunami near Haydarpasa Port is simulated to investigate effects of a more realistic tsunami that cannot be generated in a wave flume with the present state of the art technology. Discussions on practical engineering applications of this type of numerical modeling studies are given focusing on pressure distributions around the crown-wall of the rubble mound breakwater, and the forces acting on the single stone located behind the crown-wall at the rear side of the breakwater. Numerical modeling of stability/failure mechanism of the overall cross-section is studied throughout the paper.

Historical tsunami in the Makran Subduction Zone off the southern coasts of Iran and Pakistan and results of numerical modeling Heidarzadeh, Mohammad; Pirooz, Moharram D.; Zaker, Nasser H.; Yalçıner, Ahmet Cevdet; Mokhtari, Mohammad; Esmaeily, Asad (2008-06-01) Tsunami hazard in the Makran Subduction Zone (MSZ), off the southern coasts of Iran and Pakistan, was studied by numerical modeling of historical tsunami in this region. Although the MSZ triggered the second deadliest tsunami in the Indian Ocean, among those known, the tsunami hazard in this region has yet to be analyzed in detail. This paper reports the results of a risk analysis using five scenario events based on the historic records, and identifies a seismic gap area in western Makran off the southern c...
Comparison of tsunami risk assessment based on seismic and landslide generated tsunamis for the Marmara Coast of Istanbul Tüfekçi Enginar, Duygu; Süzen, Mehmet Lütfi; Kolat, Çağıl; Yalçıner, Ahmet Cevdet (2019-04-07) A high resolution tsunami vulnerability and risk assessment have been performed for the Marmara coast of the megacity of Istanbul by using the MeTHuVA (METU Metropolitan Tsunami Human Vulnerability Assessment) Method (Tufekci et al., 2018) considering seismic and non-seismic (submarine landslide) tsunami sources in the sea of Marmara. The 28 September 2018, Mw7.5 strike-slip Sulawesi, Indonesia earthquake triggered an unexpected tsunami and caused damage and loss of lives in Palu Bay. The observed tsunami h...
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...
Preliminary estimation of the tsunami hazards associated with the Makran subduction zone at the northwestern Indian Ocean Heidarzadeh, Mohammad; Pirooz, Moharram D.; Zaker, Nasser H.; Yalçıner, Ahmet Cevdet (2009-02-01) We present a preliminary estimation of tsunami hazard associated with the Makran subduction zone (MSZ) at the northwestern Indian Ocean. Makran is one of the two main tsunamigenic zones in the Indian Ocean, which has produced some tsunamis in the past. Northwestern Indian Ocean remains one of the least studied regions in the world in terms of tsunami hazard assessment. Hence, a scenario-based method is employed to provide an estimation of tsunami hazard in this region for the first time. The numerical model...
NUMERICAL MODELLING OF SOLITARY WAVE EXPERIMENTS ON RUBBLE MOUND BREAKWATERS Güler, Hasan Gökhan; Arikawa, Taro; Baykal, Cüneyt; Yalçıner, Ahmet Cevdet (null; 2016-04-16) Performance of a rubble mound breakwater protecting Haydarpasa Port, Turkey, has been tested under tsunami attack by physical model tests conducted at Port and Airport Research Institute (Guler et al, 2015). It is aimed to understand dynamic force of the tsunami by conducting solitary wave tests (Arikawa, 2015). In this study, the main objective is to perform numerical modelling of solitary wave tests in order to verify accuracy of the CFD model IHFOAM, developed in OpenFOAM environment (Higuera et al, 2013...
