Master Thesis How To Adapt To Climate Change? an Analysis of Ecosystem Vulnerability in İzmir (türkiye)(01. Izmir Institute of Technology, 2023) Salata, Stefano; Salata, Stefano; Gerçek Kurt, Deniz; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThe purpose of the thesis research is to determine how susceptible the ecosystems in the city of İzmir are to the effects of climate change and provide relevant data to policymakers so that they could develop more efficient climate change adaptation measures. İzmir city is facing challenges in addressing the vulnerabilities triggered by climate change. The biophysical components that contributed to ecosystem vulnerability in the city include the urban heat island effect, urban pluvial floods, and coastal floods. These components were evaluated using a stringent approach that utilized the most recent findings from scientific research and various technological instruments. The analysis results were provided to portray the parts of the city that were most susceptible to the effects of climate change, and the results were further evaluated to better comprehend the processes that contributed to intensifying the consequences of climate change for the vulnerable regions. A thorough investigation and in-depth inspections were carried out using representative tiles from the city, and the results showed that existence of tree and green areas, imperviousness density, Footprint Ratio, Floor Surface Index, and road ratio were the most contributing factors of climate change vulnerability. Following the process of analysis, a systematic of planning and planning parameters were developed that embraced nature-based solutions and a performance-based planning approach for enabling the adaptation of settlements to climate change. The findings contributed significantly to the expanding body of knowledge on how to adapt to the effects of climate change and provided suggestions for efficient measures to mitigate the related risks in İzmir.Master Thesis Investigation of Coastal Flood Problem in İzmir Bay(Izmir Institute of Technology, 2022) Özbahçeci, Bergüzar; Özbahçeci, Bergüzar; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyIzmir, with its long coastline, is one of Turkey's leading tourism and trade cities. The coastal flood is an important problem in İzmir Bay. The literature review shows that there is no study that covers all the elements of the problem such as wind and wave climate, fluctuations in the sea level and coastal flood calculations in İzmir Bay. In this study, the ERA5 wind dataset developed by the European Center for Medium Range Weather Forecasts was used to determine extreme wind speeds. The data were verified using in-situ wind measurements data. Then, the fluctuations in sea water level caused by astronomic and atmospheric effects such as tides, wind and wave set-up and barometric effects were examined by the analysis of sea water level measurement data of the Izmir Metropolitan Municipality in Bostanlı and Pasaport and the tide gauge station data of the General Directorate of Mapping in Mentes. The long-term trend of sea level was examined using Theil-Sen and the line of best-fit methods. Then, the reliability of the trends was demonstrated by performing the Mann-Kendal test. Calculated extreme wind speeds and sea level fluctuations were taken into account to estimate the waves in front of coastal protection structures using a wave model called SWAN. Then, in order to predict the coastal flood amounts, the wave overtopping was calculated by the artificial neural network method. It is concluded that the most sensitive places in İzmir Bay in terms of coastal floods are the areas protected by vertical walls.
