Göcek – Fethiye Bay is a unique marine area in Turkey; however, increasing human activities and related pollution affect decrease in the water quality. The water quality can be reserved if there is sufficient amount of water exchange between bays and the offshore region. The coastal morphology and wind driven currents and tidal motion are other important factors facilitate circulation and improve the quality marine environment. Therefore, all factors forcing water exchange should be investigated and the adverse effects (mainly from human activities) should be evaluated by proper methods. This study is specifically concerned with three - dimensional numerical circulation modeling of Göcek and Fethiye Bays. Bathymetric, oceanographic and meteorological site surveys are conducted before setting up the numerical model, MIKE 3 Flow Model Hydrodynamic Module. Monthly and seasonally met – ocean variations on the site was studied by using database available from Turkish State Meteorological Service. The circulation model within the boundaries was set up by applying at least two main directions of current and wind for twelve months with total twenty-four different scenarios. On the basis of the results of this study, the water exchange capacity of Göcek and Fethiye Bays, and investigations on improvements of water exchange and related environmental parameters are performed. Future recommendations for the management perspective on increasing the water quality will be developed.

Evaluation of the best management practices to control agricultural diffuse pollution in lake mogan watershed with swat model Özcan, Zeynep; Alp, Emre; Kentel Erdoğan, Elçin; Department of Environmental Engineering (2016) Lake Mogan which is located in Gölbaşı County, Ankara, Turkey is one of the most important wetlands of Turkey and it was declared as Special Environmental Protection Region in 1990. Total area of semi-arid Lake Mogan watershed is 970 km2 and dry farming is practiced approximately in 40% of the basin. Therefore, agricultural diffuse source pollution is a serious concern in the watershed. In the context of this thesis, the effects of implementation of different agricultural best management practices on sedime...
Maastrichtian-Thanetian planktonic foraminiferal biostratigraphy and remarks on the K-Pg boundary in the southern Kocaeli Peninsula (NW Turkey) Sarigul, Volkan; Hakyemez, Aynur; Tuysuz, Okan; Can Genc, Sengul; Yılmaz, İsmail Ömer; Özcan, Ercan (2017-01-01) The Kocaeli Peninsula (NW Turkey) provides one of the best exposed deep marine Upper Cretaceous-Palaeocene sections in north-western Anatolia. The biostratigraphic framework from three sections, namely Belen, Bulduk, and Toylar, in the southern part of the Kocaeli Peninsula is established by means of planktonic foraminifera. A very rich planktonic foraminiferal assemblage analysed both in thin sections and washed residues records a biozonation ranging from the Contusotruncana contusa (CF6) Zone (Maastrichti...
Quality Assessment of the Armourstones for Some Black Sea Rubble Mound Breakwaters, Turkey Ozden, U. A.; Topal, Tamer (2007-01-01) The Black Sea coastline is a hazardous region in Turkey, especially in winter, due to the dominant wave action. Therefore, rubble mound breakwaters used as ship shelters are vital structures, especially for the fishermen. Construction of the breakwater requires good quality, durable armourstones. Due to the nature of the rubble mound breakwaters, armourstones of various sizes and types are used in the construction of these structures. The deterioration of these armourstones with time may result in the failu...
Quality assessment of armourstone for a rubble mound breakwater (Sinop, Turkey) Topal, Tamer (Springer Science and Business Media LLC, 2004-10-01) Helaldi is a fishing town in the central Black Sea region where construction of a rubble mound breakwater is being planned. The construction of the breakwater requires good quality durable armourstone. Several laboratory tests are performed for the quality assessment of the two potential armourstone, namely, limestone and sandstone. The quality evaluation of the stones is done on the basis of CIRIA/CUR criteria, saturation coefficient, wet-to-dry strength ratio, and the rock durability index. The quality ev...
A review of plastic pollution in aquatic ecosystems of Turkey Çevik, Cem ; Kıdeyş, Ahmet Erkan; Tavşanoğlu, Ülkü Nihan ; Kankılıç, Gökben Başaran ; Gündoğdu, Sedat (2021-12-01) Turkey is one of the major plastic pollution sources in the Mediterranean and the Black Sea. This review summarizes present information, data, and legislation on plastic pollution in Turkish aquatic ecosystems. According to results derived from reviewed studies, both macro- and microplastic pollutions were documented in Turkish aquatic ecosystems. Most of the studies on plastic pollution in Turkish waters were performed in the marine environment while only four were conducted in freshwater environments. Spa...
