    The need to energy has become an important reality for human life with the increase in living standards and population. İzmir has important renewable energy sources especially solar energy. Rapid urbanization and environmental problems due to internal migration after the 1960s have made renewable energy sources a priority because of the wrong implementations of urban policies in İzmir. In order to talk about energy potential, it is first necessary to talk about and analyze the land potential. It is necessary to determine the true criteria and methods for true analyzes of the suitable areas for efficiency and sustainability. The study presents a GIS-based approach to identify the most suitable area for Solar Power Plants (SPP) development in İzmir. The first suitability map includes 9 criteria. The last suitability map includes the first suitable map results and criteria of land capability class (10th criteria) using the same method. It can be said that the SPP installation is more suitable, especially the northern part of İzmir and districts of border. When the evaluation is compared, it can be said that İzmir has fertile lands and it should definitely be taken into account in energy projects. It also draws attention importance of land use decisions and legislation while choosing the suitable area from perspectives of planning. In addition, the current and potential solar energy area choices were evaluated together with the results which are produced for the study area in terms of land decisions and planning.

    (Izmir Institute of Technology, 2019) Erdem, Ezgi Gül; Akpınar, Figen; Akpınar, Figen; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    Cities are complicated and dynamic structures. Urban agenda has changed constantly. Urban planning has to follow and reshape this dynamism as a return. Cities are under constant restructuring with parallel to spatial, economic, social and political conditions. In recent years, urban transformation has become turning point in planning system and occupied dominant role as a policy tool in Turkish context. Urban transformation has come to the planning agenda as an indispensable policy tool. Especially in the last two decades, urban transformation projects became a tool of spatial restructuring processes and solving major problems such as illegal housing, disaster risk, and uncontrolled urban sprawl. Moreover, with the generalization and reinterpretation of the context of transformation caused conceptual and practical confusion. The implementation of the urban transformation projects is taken place almost in all Turkish cities; however, it has felt more in big metropolitan cities as in the case of first Istanbul and then Ankara. The city of İzmir, seems to be subjected to all these discussions. This study first discusses the urban transformation concept as a tool of planning, by clarifying its principles on a global scale. After, it evaluates Turkey’s performance on a holistic approach, which means all interventions that caused transformation at the citywide level in the case of İzmir central areas. The analysis has conducted using multidimensional spatial data in GIS database in relation to general policies and legislation. All urban transformations projects in İzmir have digitalized geographically on a map to evaluate their location and attributes in relation to urban plans. As a result of these analyses, it has been concluded that despite the urban transformation concept was proposed as a solution to problems of the cities, it has evolved into a new problematic because of fragmented and speculative rent seeking activities or ineffective applications. The study aims to highlight these deficiencies and offer solutions.

    Determination of Flood Risk Areas and Mitigation Strategies: a Case Study of the Menemen Plain, Izmir
    (Izmir Institute of Technology, 2019) Günseli, İsmail Gökhan; Demirkesen, Ali Can; Demirkesen, Ali Can; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    According to literature, natural disasters are increasing worldwide. Among them, flood is the most common and has the most impacts. Because of global warming and climate-patterns changing, frequency of floods has increased significantly. Also, the greatest impact among the human-oriented reasons are urbanization and industrialization. With the spread of urbanization, population in cities around the world has increased rapidly; natural areas have been destroyed, cities have been expanded. These changes have increased fragility in cities. Therefore, objective of the study was to determine flood risk areas and minimize negative impacts of floods. Accordingly, the study area; the Menemen Plain and its surroundings were found worthwhile to examine due to its topographic, climatic and hydrological structure. In this study, weighted-overlay analysis method was used in ArcGIS to determine flood risk areas employing six criteria. Therefore, six criteria that have an impact on flooding were identified as; (1) slope, (2) elevation, (3) distance from rivers, (4) distance from junction-points of river, (5) land use/cover, and (6) rainfall. The weights of criteria were assigned by land and literature investigation. According to the study, the highest risky flood locations with more population were seen as Emiralem, Kesik, Buruncuk and Çavuşköy settlements. On the other hand, medium flood risk settlements with more population were found as Seyrek, Yahşelli, Sasalı and Yenibağarası. Consequently, resilience and mitigation strategies were identified. It was stated that flood risk management should be managed in a participatory manner with a holistic approach and public-private-individual partnership with structural, non-structural measures.

    Investigation of Vegetation and Agricutural Soils in Relation To Groundwater by Using Geographic Information Systems (gis): a Case Study of Manisa, Alaşehir Basin
    (Izmir Institute of Technology, 2018) Budak, Seda; Demirkesen, Ali Can; Demirkesen, Ali Can; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    Groundwater is a natural resource that is directly or indirectly affected by any intervention in nature that we use in all areas of our life. In this sense, the issue of the groundwater is a study-subject that interests many professions and researches. Urban planning is a profession area that is directly related to the groundwater issues as decision-making on spatial and functional decisions about the city and the natural environment. However, groundwater resources are not taken into account as aboveground natural resources during the planning phase. Plans without consideration of groundwater potential cause threatening consequences for both existing natural resources and residents in the region. For this reason, the focus point of the thesis is the groundwater and its determination and investigation of relationship among the groundwater, vegetation, and agricultural soils. The aim of this thesis is to determine the groundwater potential (GWP) locations of Alaşehir Basin by a multi-criteria (proxies) method based on Geographic Information System (GIS) integrated with Remote Sensing (RS). The method used in this study includes 10 proxies as mult-criteria that play important roles on determination of the potential of the groundwater, combining these proxies in a digital media and illustrating output image maps of them. These proxies are: Normalized Difference Vegitation Index (NDVI), Modified Normalized Difference Water Index (MNDWI), land-use land-cover (LULC), lineament, topography (Digital Elevation Model – DEM), slope, drainage, lithology, hydraulic conductivity, and soil types. The main data sources of the study are: Landsat-8 OLI multi-spetral satellite image bands, the Aster Digital Elevation Model (DEM) of the study area and the GIS data layers from the institutions and research studies. According to study, the most GWP locations are seen in northeast of Salihli, in southeast of Alaşehir and around Dereköy. This findings are so important for planning in terms of groundwater pollution risk management.

    This study presents a GIS-based multi-criteria approach to identify the most preferred or suitable site for wind farms development in Karaburun Peninsula, İzmir. Criteria for analysis have been identified based on literature review and experts’ opinions. The selected criteria include environmental, technical, and economic as well as social factors. In order to estimate the weights or relative importance of the criteria, the pairwise comparison method in the context of Analytic Hierarchy Process (AHP) is implemented. The overall suitability of the study area is determined through the Weighted Overlay method, which is a sufficient weighted approach in geographical information system (GIS) environment. The outcome or suitability map is classified into five scored classes from the most suitable to less suitable and restricted area. On the whole, as the selection of optimal site for the wind farm development is a multi-dimensional process, this thesis intends to consider the following three significant subjects; (a) evaluating and identifying the most influential criteria for land suitability analysis of wind farms, (b) applying AHP as a multi criteria decision-making method to determine the criteria weights, (c) utilizing GIS as a tool to overlay the overall criteria and consequently to identify the potentially suitable location for the wind farms development. Regarding to the above mentioned, eight the most influential available criteria, which are consisted of wind potential, distance from preservation area, distance from settlements, forest, slope, elevation, distance from roads, and agriculture area are identified. Base on pairwise comparison different weights for each criterion is determined. Finally, by using GIS the suitability map for the study area is provided and the result compared with the existing wind farm locations.
