Article Citation - WoS: 1GIS-AHP APPROACH FOR A COMPREHENSIVE FRAMEWORK TO DETERMINE THE SUITABLE REGIONS FOR GEOTHERMAL POWER PLANTS IN IZMIR, TURKIYE(Konya Teknik Univ, 2024) Koca, Kemal; Karipoglu, Fatih; Ozturk, Emel ZerayGeothermal energy is gaining more reputation and importance around the world. Correspondingly, suitable location selection is a critical step and has become necessary for the successful installation and operation of geothermal power plants. This study investigated suitability of & Idot;zmir region, located in the Aegean part of T & uuml;rkiye, in terms of geothermal power plants applications by using the combination of Geographical Information System and Analytic Hierarchy Process. Based on the request of power plants, thirteen important criteria were evaluated under three main categories named as physical (C1), environmental (C2) and technical (C3). Moreover, expert's opinions were taken into consideration to calculate the importance of these criteria. Key results showed that & Idot;zmir was suitable for geothermal power plants. The final suitability map layer pointed out that %8.73 (1.037 km2) of total area were determined as highly suitable regions in terms of installation. In addition, the obtained suitability map layer was compared with actual geothermal power plants. Based on the comparison study, power plants in Seferihisar were moderately suitable for geothermal power plants while the location of Bal & ccedil;ova power plant was highly suitable. Regarding the suitability assessment in the present study, the location of Dikili power plants had the least suitability score.Article Citation - Scopus: 2The Uncertain Certainty of a Nightmare: What If Another Destructive Earthquake Strikes Izmir (türkiye)?(Mdpi, 2024) Salata, Stefano; Uzelli, TaygunOn 6 February 2023, near Kahramanmaras in south-central Turkiye, an event underscored the vulnerability of cities to seismic activity, revealing a lack of preparedness for substantial shocks. The contributing factors are manifold, yet fundamentally, the collapse of buildings and infrastructure can be attributed to an underestimated capacity for meticulous settlement planning (location) and the adoption of advanced techniques for resilient construction (structure). Regrettably, as has been investigated by many research works, ordinary urban planning in Turkiye hardly finds ways to integrate the vulnerability analysis for settlement expansion, which includes the full integration of geological characteristics with the analysis of building sensitivity. With this work, we wanted to build a composite risk index based on earthquake vulnerability, hazard amplification map, and exposure. We designed the composite index in Izmir's basin, Turkiye's third most populated city, to answer the question: What if a destructive earthquake strikes this densely settled area? The results illustrates how the coupled integration of digital data on geology with settlements and infrastructure in a Geographic Information System environment can be used to produce risk maps and plan the anthropic system's adaptation carefully. Findings demonstrate the city is highly vulnerable to earthquakes and identify priority areas for planning intervention, relocation, and renovation of buildings.Article Modernity, Hygiene and Display of the Body(Yıldız Teknik Üniversitesi, 2016) Yılmaz, EbruThis article focuses on health museums as a building type introduced to the architectural medium at the beginning of 20th century by modern thinking, the ideal of creating a healthy society as a guarantee of progress and development. Health museums provided representation for concepts of modernity and hygiene in a built environment by being spaces that displayed the human body and exhibits related to diseases, hygiene, and medical developments. A modest building in scale and content, the Izmir Health Exhibition building of the Izmir Fair was analyzed in this study to show how it contributed to 1920s and 1930s modern architecture in Turkey and what were the representational meanings of the messages transmitted. The existence of this building, constructed in 1937 in Izmir, should be understood in the context of health policies from all around the world, social engineering efforts, and the process of modernization. The building is an example of a use of modern architecture, but of a type that is waning in popularity in today's contemporary world. Looking back at this building today helps us understand the rising and declining value of modernity in the discourse of hygiene and its effect on the field of architecture. The contribution of the Izmir Health Exhibition building to early modern Turkish architecture is discussed with reference to similar exhibitions and museums around the world.Article Citation - WoS: 1Citation - Scopus: 1The Multi-Level Policy Learning of Environmental Policy: Insights From Izmir(Routledge, 2019) Velibeyoğlu, Koray; Mengi, OnurA European Union (EU) membership perspective is important for Turkey's harmonization with EU standards, which could have positive outcomes especially in the area of smart environmental management. However, as recent political developments suggest, Turkey is losing hope of full EU membership, and is searching for alternatives, such as privileged partnership. Active contributions of city-level good practices are urgently needed. Policy learning is a part of this process, and an emergent result of ever-changing negotiations involving a multiplicity of actors at the multi-level perspective (MLP). The present study investigates the glocal environmental policy of Izmir, via a review of recent governmental environmentally sensitive local innovative practices. The findings reveal that innovative environments that increase learning-by-doing and learning-by-using will become critical for environmental policy learning in Izmir and perhaps beyond.Conference Object Citation - WoS: 35Detection of Flood Hazard in Urban Areas Using Gis: Izmir Case(Elsevier, 2016) Özkan, Sevim Pelin; Tarhan, ÇiğdemThe aim of this study is to predict the potential flood-hazard areas using Shuttle Radar Topography Mission-Digital Elevation Model (SRTM-DEM). The study area is the province of Izmir. SRTM-DEM of the Izmir Province has 90 m of grid size resolution; 45 m of horizontal accuracy; and 15 m of vertical accuracy. Within this study, obtaining spatial information on flood hazard by using Izmir digital terrain models and by 3D analysis that will help to achieve the regional flood hazard management scheme is aimed. Flood-hazard areas have been identified by the use of digital elevation model covering the study area. The main rivers in the study area are Gediz, Kucuk Menderes and Bakircay that creates the coastal flood plains. In order to estimate the spatial distribution of flood-hazard areas in Izmir, five factors are used: flow accumulation, land use, slope, rainfall intensity, and elevation. The classic hydrological modelling approach was applied to determine the rainfall intensity; rainfall intensity of study region is created with the average amount of total rainfall intensity of fifteen stations in the two basins per minute using the interpolation method (spline interpolation). By the digitizing rivers, topography, flow direction and flow accumulation, as well as the flood detention areas are determined. These factors were combined with the weighted overlay method to determine categorized flood-hazard areas. As a result, possible flood-hazard areas have been determined in the case of Izmir Province.

Izmir Tube Tunnel Project Proposal Under Scrutiny(MDPI Multidisciplinary Digital Publishing Institute, 2019) Duvarcı, Yavuz; Yiğitcanlar, TanBuilding underwater tube tunnel crossings to ease the urban congestion problems has become a popular approach for many cities across the globe. London, New York, Istanbul, Hamburg, Sydney and Brisbane are among these cities. However, the effectiveness and externalities of these expensive mega urban infrastructures have also been questioned widely among urban, transport and environmental planning scholars. Given the international popularity of the topic, this study places a new tube tunnel crossings project from Izmir, Turkey under the microscope. In this heuristic simulation study, policy-on scenarios were tested to determine possible impacts of the underwater tube tunnel-crossing project. The traffic impacts are discussed using simulations assigning the initial origin-destination data. The results of the study revealed that, given the two locations, outer and inner locations over the dagger-shape bay, the capacity increments on the bridge links and the links around the periphery highway did not bring any effective solutions beyond some minor improvements. The findings disclosed that the ineffectiveness of the tube tunnel crossing might be due to the excessive congestion happening all over the downtown area, which clogs the passageways to the bridge. The paper highlights the limitations of the tube tunnel-crossing project, emphasises the need for comprehensive investigations before committing to the project and advocates the emphasis to be actually given for sustainable mobility.Article Citation - WoS: 3Citation - Scopus: 4İzmir’deki Ulaştırma Projelerinin Kentsel Eğilimlere Etkileri(TMMOB İnşaat Mühendisleri Odası, 2008) Duvarcı, Yavuz; Selvi, Ömer; Günaydın, Hüsnü Murat; Gür, Güneşİzmir’deki önemli ulaştırma projelerinin kentsel eğilimlere olan etkileri Delphi yöntemi sonuçları temel alınarak analiz edilmiştir.

The study focuses on Izmir, Turkey; exploring its potential as an emerging creative city. The methodology is a descriptive analysis of recent urban design and planning activities of creative cities, reviews projects and strategies in Izmir. Findings provide a framework for place management tools and their strategic use for integration of art, design, creativity and knowledge in creative cities. Place management is used as a tool for image building and identity enhancement, and for quality of place to attract creative and knowledge workers. In the case of Izmir, hard factors triggered the formation process whereas soft factors have taken strengthen the initiative. However, both of them are yet not strong enough to creative public awareness and critical mass.Article Citation - WoS: 81Citation - Scopus: 107In-Between Spaces and Social Interaction: a Morphological Analysis of Izmir Using Space Syntax(Springer Verlag, 2016) Can, Işın; Can Traunmüller, Işın; Heath, TimThis research tackles the intermediate spaces between buildings and the street, by examining the definition and importance of spatial configuration in relation to urban morphology and social relations. It also analyses how the organisation of in-between space affects social interaction in different urban forms. To understand the complex relations and socio-spatial structure of the city, it is important to use mixed methods. This research utilises various methods to focus on three dissimilar urban morphologies in Izmir, Turkey. Two inner city quarters and one modern housing estate of middle- and high-income groups are compared using space syntax analysis and snapshot observations. These neighbourhoods are selected according to their syntax measures from more integrated to segregated neighbourhoods in the axial analysis. And for a detailed zoomed-in analysis, similar diameter areas are covered for observations. Subsequently, activity patterns are observed at different times of the day, one weekday and one Sunday in three cases. In each neighbourhood, syntactic measures of all selected streets are correlated with these recorded activities. This study reveals that connectivity of streets is important for supplying niches that trigger long-duration activities and social interaction. In modern estates, stationary activities are not correlated strong enough with movement as it is in inner city neighbourhoods. Additionally, in-between spaces increase the frequency of social interaction and co-presence of people particularly in more integrated areas. However, this is only one element in developing sense of community. Further research is needed especially in correlating space syntax with environmental issues, as well as people’s behaviour.Article Citation - WoS: 13Citation - Scopus: 12The Role of Government Policies and Strategies Behind the Shrinking Urban Core in an Expanding City Region: The Case of Izmir(Taylor and Francis Ltd., 2014) Özatagan, Güldem; Eraydın, AydaOver the last few decades, the term urban shrinkage has come to be accepted as a valid concept in international academic circles, and has gradually gained importance, with its causes the subject of well-documented discussion. While previous discussions of urban shrinkage have directed attention to cities shrinking as a whole, recent research started to recognize the case of shrinkage in growing cities and regions. As such, recent discussions of urban shrinkage indicate that patterns of shrinkage vary considerably from city to city, and from sub-region to sub-region, with the importance of local dynamics in responding to changing economic pressures given much consideration. Recent studies have tended to disregard the role of government policies and strategies put in place to facilitate the adaptation of the urban economies to the new conditions. Taking Izmir as an example, being a fast-growing metropolitan region in Turkey, this paper presents evidence of government policies and strategies aimed at enhancing the development of peripheral areas that have led to shrinkage of the metropolitan core. This paper focuses on this experience and discusses its implications.
