The Bosphorus is oceanographically very complicated two-layer stratified strait where denser water from the Marmara Sea flows towards North under the lighter water which is frequently flowing from the Black Sea towards South. The water level difference between both ends of the Bosphorus varies seasonally within the range of -0.2 and 0.6 m. The seasonal variability depends mainly on the water level changes in the adjacent basins related to the hydrological cycle, short-term changes in the atmospheric pressure and the wind characteristics. These variations together with the depth and alignment of the cross section along the strait dominate the spatial and temporal variations and sometimes sharp changes in the flow pattern in three dimensions. Although these hydrodynamic conditions are critical for all marine and hydraulic works along the Bosphorus, there was riot continuous long-term measurement for a sufficient time span in the strait for detailed evaluation of the current climate. An extensive site surveying work including current, wind, pressure and water level measurements was carried out between September 2004 and January 2006 in relation to the design and construction requirements of the Bosphorus Tube Crossing Project. In this study, the characteristics of stratified flow in the Bosphorus Strait and their relation to local and regional, short- and long-term changes in the meteorological parameters are studied by using the measurement data and the results are discussed comparatively.

Application of a three-dimensional numerical model to the idealized conditions of the bosphorus strait. Sözer, Adil; Özsoy, Emin; Department of Marine Sciences (2002) The Bosphorus Strait is a narrow and shallow channel between the Sea of Marmara and the Black Sea which plays an important role in the Turkish Straits System connecting the Black Sea and the Mediterranean Sea. The exchange flow through the Bosphorus Strait is principally determined by geometry and stratification, and exhibits a complex nonlinear response to forcing by the net water budget, pressure and wind setup effects in adjacent basins. This study aims for a better understanding of the behaviour of the ...
Observed basin-wide propagation of Mediterranean water in the Black Sea Falina, Anastasia; Sarafanov, Artem; Özsoy, Emin; Turunçoğlu, Ufuk Utku (2017-04-01) Mediterranean water entering the Black Sea through the Bosphorus Strait forms middepth intrusions that contribute to the salt, heat, and volume balances of the sea, ventilate its water column at intermediate depths and restrain the upward flux of hydrogen sulfide from deeper layers. Despite the importance for the Black Sea environment, the circulation of Mediterranean-origin water in the basin is fundamentally underexplored. Here we use hydrographic data collected from ships and Argo profiling floats to ide...
Non-hydrostatic Modeling of Exchange Flows Across Complex Geometries Ilicak, Mehmet; Oezgoekmen, Tamay M.; Oezsoy, Emin; Fischer, Paul F. (2009-01-01) Flows between ocean and marginal sea basins are often connected by narrow channels and shallow sills. In this study, we address the effect of lateral and vertical geometric constrictions on mixing and hydraulic control. We conduct a set of numerical experiments of the lock-exchange problem in the presence of lateral and vertical contractions. Large eddy simulations (LES) are carried out using the high-order non-hydrostatic spectral element model Nek5000. A spanwise-averaged 2D non-hydrostatic model, denoted...
Modelling long term morphological changes with XBeach case study of Kizilirmak River mouth Baykal, Cüneyt; Güler, Işıkhan; Özyurt, Gülizar; Söğüt, Erdinç; Güler, Hasan Gökhan; Doğan, Gözde Güney (2015-04-17) 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 construction of flow regulatory structures in the following years. This drastic decrease in the amount of sediment carried by the river resulted in a severe shoreline retre...
The distribution of man-made and naturally produced halocarbons in a double layer flow strait system Fogelqvist, E; Tanhua, T; Basturk, O; Salihoglu, I (1996-08-01) The Bosphorus Strait, which connects the Black Sea and Mediterranean Sea via the Marmara Sea, is characterised by two distinct water masses. The upper layer consists of low density Black Sea water (sigma-t 10-11) flowing southward, and it is underlain by high density water (sigma-t > 28) of Mediterranean origin flowing northward. The sharp density gradient between the two layers is due to the difference in salinities. Here we report measurements on a suite of low molecular weight halocarbons together with b...
