Low-lying geographies are quite attractive and preferable for the populations in terms of settlement, agriculture and tourism. Based on the recent findings of archaeological research, it can obviously be seen that people has generally settled and developed civilizations on low-lying areas. As one of the impacts of global climate change, accelerated sea level rise mainly due to thermal expansion of surface waters has become a growing threat especially for low-lying areas worldwide. Among the most profound impacts of sea level rise, coastal erosion, inundation of lands, flooding of coastal areas due to increased storm surges and salt water intrusion to fresh water resources (Ozyurt, 2010) come into prominence in the long term. Fethiye as an attractive touristic destination in Turkey is exposed to many hazards like tsunamis and earthquakes throughout the history (Minoura et al. 2000). Topographical characteristics of this ancient town of Turkey, brings its importance into forefront in terms of the need for its coastal vulnerability assessment within the CVI (Coastal Vulnerability Index to Sea Level Rise) Model and FCVAM (Fuzzy Coastal Vulnerability Assessment Model) (Ozyurt, 2010). The main objective of this thesis is to determine the vulnerability of Fethiye in order to be a guide for decision makers in taking measure and preparing adaptation plans for its sustainability in the long term scale. Within the scope of this thesis, the vulnerability assessment studies with both fuzzy logic and parameter based basic version are conducted and compared. The preliminary model result gives the coastal vulnerability level as high-moderate, but the fuzzy coastal vulnerability assessment model obtains vulnerability level within the moderate range. In light of the results of both model studies, inundation, coastal erosion and flooding due to storm surge rank in vulnerability priority as the most salient coastal impacts of sea level rise. This study aims to give an idea for authorities and decision makers on the optimal resource allocation and adaptation plans in the sense of coastal zone management practices.

Statistical and spatial approaches to marina master plan for Turkey Karancı, Ayşe; Ergin, Ayşen; Güler, Işıkhan; Department of Civil Engineering (2011) Turkey, with its climate, protected bays, cultural and environmental resources is an ideal place for yacht tourism. Subsequently, yacht tourism is increasing consistently. Yacht tourism can cause unmitigated development and environmental concerns when aiming to achieve tourist satisfaction. As the demand for yacht tourism intensifies, sustainable development strategies are needed to maximize natural, cultural and economic benefits. Integration of forecasts to the strategic planning is necessary for sustaina...
A case study on the stability of berm type coastal defense structures Fışkın, Gökçe; Ergin, Ayşen; Department of Civil Engineering (2004) Coastal defense structures have primary importance from obtainabilty of resources and benefits served by the coastal regions point of view. However, the construction of coastal defense structures demand a high amount of investment. Therefore, in order to reduce the risk of collapse of these structures, model studies should be carried during the design process. In this study, model investigations were carried out on Eastern Black Sea Highway Project regarding the serviceability and damage thus stability para...
Evaluation of effects of thermal tourism on local economy : the case of Thermal District of Yalova Piri, Taner; Kayasü, Serap; Department of City and Regional Planning (2012) Tourism and local economic development are closely linked. Tourism can have a constructive effect on local economy and may help balance some of the inequalities between different parts of a country. Thus, in many regions in the world, the tourism sector is accepted as one of the greatest sources of economic growth and job creation. In line with economic contribution of the sector, tourism policy has become an instrument for territorial development and for enhancing an area’s opportunities. It appears that t...
CLASSIFICATION OF SENSITIVE AND LESS SENSITIVE AREAS ALONG THE AEGEAN COASTAL AREAS OF TURKEY Avaz, Gulsen; KÜÇÜKSEZGİN, FİLİZ; Tuğrul, Süleyman; Tan, Ibrahim; Günay, Aslı; Kuzyaka, Ersan; Ozkan, Melek (2018-01-01) In the last few decades, due to an enormous increase in urbanization, industrialization and tourism activities, the risk of eutrophication has been gradually gaining more significance, especially for the closed and semi-closed bays in Turkey.
Valuation of environmental improvements in a specially protected marine area: A choice experiment approach in Gocek Bay, Turkey Can, Ozge; Alp, Emre (Elsevier BV, 2012-11-15) Although the Gocek Bay area was declared as a specially protected area by General Directorate of Natural Assets Protection, the region is threatened because of pollution resulting from increased boat tourism and lack of efficient policies. Extensive measures are being planned in order to protect the region. Coastal management requires the use of technical, social political and economic tools to create a comprehensive management strategy. For environmental investments, it is necessary that benefits and the c...
