Ülkemizde İlkadım/Samsun yöresinde bulunan Kurupelit Yat Limanı’nın dalgakıran yapısı inşaatı sonrasında kıyı boyunca belirgin ölçüde kıyı erozyonu gözlemlenmiştir. Ayrıca, dalgakıran yapısının çevresinde ise birikmeler gözlemlenmiştir. Kıyı şeridinde meydana gelen değişikliklerin ilerleyen dönemlerde de benzer şekilde devam edeceği öngörülerek lim...

This paper presents experimental results on the cross-shore distribution of non-buoyant microplastic particles under irregular waves propagating, shoaling and breaking on live sediment sloping beds. Eighteen microplastic particle groups having various shapes, densities, and sizes are tested. The experiments consider two initial bottom configuration...
Article
In the present study, the motion of a single and the motion and collision of two spheres on a horizontal area under solitary wave attack are investigated, constituting a unique and integrated dataset. Sixteen experimental cases are considered on four experimental configurations changing the number of spheres, the porosity of the bottom, water level...
Article
(English below) Gel-git, mevsimsel değişiklikler, dalga kabarması/alçalması, fırtına kabarması ve küresel ısınmaya bağlı su seviyesi değişimleri sonucunda ortalama su seviyesinde gözlenen değişimler, taş dolgu kıyı koruma yapılarının tasarımlarının ve performanslarının değerlendirilmesi ile doğrudan ilgilidir. Bu tip yapılar için en kritik su seviy...

The July 20, 2017 Bodrum–Kos Earthquake caused tsunami wave motions and damage in the south of Bodrum Peninsula, Turkey, and on Kos Island, Greece. Immediately after the earthquake, we conducted several post-tsunami field surveys including interviews in coastal zones impacted by the tsunami, i.e., the coastlines of Bodrum Peninsula, Karaada Islet a...

A magnitude (Mw) 6.6 earthquake occurred on July 20, 2017 (22:31 UTC) in between Bodrum, Turkey and Kos Island, Greece. Field surveys are conducted in the region (Yalciner et al., 2017) including southern and northern coastlines of Bodrum peninsula, Karaada, Akyaka town and Kos Island. A tide gauge located in Bodrum main port recorded the tsunami....

In this study, performances of interFoam solver of OpenFOAM and CADMAS-SURF computational tools with several turbulence modelling approaches on the numerical modelling of long wave motion and its interaction with a vertical wall based on the physical model experiments presented by Arikawa (2015) are investigated and compared. IHFOAM is used as wave...

In this study, physical and numerical test are carried out focusing on the motion of two solid spheres under solitary wave attack. The numerical model CADMAS-SURF/3D-2F-DEM coupling a multiphase flow solver solving Reynolds Averaged Navier-Stokes Equations based on a porous body model and a discrete element method solver for Newton’s equations of m...

11 Mart 2011 tarihinde gerçekleşen 9.1 şiddetindeki depremin yarattığı tsunami, Japonya’nın doğu kıyısı boyunca çok sayıda can kaybına ve ciddi hasara yol açmıştır. 2011 Tsunamisi’nin ardından Japonya’da yapılan planlama ve yeniden yapım çalışmaları alınması gereken önlemlere önemli bir örnek teşkil etmektedir. Bu çalışmada afetin beş yıl ardından...
Article
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® environment. The numerical mode...

20 Temmuz 2017'de, Türkiye saati ile 01.31’de Gökova Körfezi'nde meydana gelen şiddetli deprem Bodrum Yarımadası’nın güneyindeki bazı küçük koylarda güçlü dalga hareketlerine ve hasarlara neden olmuştur. Deprem ve dalga hareketleri Yunanistan’ın Kos Ada’sında da hissedilmiştir; Kos limanında yoğun bir su baskını ile liman altyapısı ve bazı tekneler...

A strong earthquake (Mw=6.6) of normal faulting striking about E-W occurred on July 20, 2017 (22:31 UTC) in between Bodrum town (Turkey) and Kos island (Greece). The earthquake caused a tsunami which affected the coast of Bodrum peninsula and the northeast coast of Kos island. Two post-event tsunami field surveys were performed. The first one was h...
Article
Tsunamis are high-impact, long-lasting disasters, which in most cases allow for only a few minutes of warning before impact. The amount of energy behind huge tsunami waves can cause severe destruction when it hits land and consequently causes massive loss of human life. The impact of tsunami can be considered in social, environmental, and economic...

The 2011 Tōhoku 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...

Wind speed data is a key input for many meteorological and engineering applications. Many institutions provide wind speed data with temporal resolutions ranging from one hour to twenty four hours. Higher temporal resolution is generally required for some applications such as reliable wave hindcasting studies. One solution to generate wind data at h...

Ports are one of the most vulnerable coastal utilities in case of marine natural hazards such as tsunamis and need to be protected against their devastating effects. Thus, studying the effects of tsunamis on protective structures such as breakwaters is critical. The Sea of Marmara is a part of an active earthquake zone that has generated tsunamis i...

The Bafra alluvial plain, where the Kızılırmak River discharges into the Black Sea, is one of the most critical examples of severe coastal erosion problems in Turkey. The amount of sediment carried by the Kızılırmak River has decreased from approximately 23 million ton per year to 0.46 million tons/year starting from 1960s as a result of constructi...

An example study showed that there may be 70% difference in armour stone weight when Van der Meer (1988) and Van Gent et al. (2004) formulas are applied as recommended by “The Rock Manual: The use of rock in hydraulic engineering” (2007) with specific design constraints. In this paper, questions arise in the application of these formulas and their...
Conference Paper
For the stability of rubble mound coastal defense structures, Hudson (1959) developed a formula based on model tests with regular waves. Later, a formula by Van der Meer (1988) is given for relatively deep water conditions at the toe of the structure with an application to moderate shallow water based on model tests with irregular waves. Van Gent e...
