Article Citation - WoS: 1Citation - Scopus: 1Groundwater Recharge Estiaton in the Alaşehir Sub-Basin Using Hydro-Geochemical Data; Alaşehir Case Study(Springer, 2021) Tonkul, Serhat; Baba, Alper; Şimşek, Celalettin; Demirkesen, Ali CanThe issue of groundwater recharge has gained importance in countries where there is not enough water supply to the aquifer. However, groundwater recharge is a difficult parameter to determine. This difficulty stems from factors such as the location of the area to be studied, time, cost, and hydrological data. Numerical, isotope, and chemical approaches are used in groundwater recharge investigations. Numerical and chemical approaches are more costly and time-consuming than chemical approaches. This study aims to ascertain alluvial aquifer recharge in Alaehir (Manisa) sub-basin using chemical approaches (Chloride Mass Balance Method) and its applicability. For this purpose, research wells were drilled at 25 different points in the alluvial aquifer, water sampling was done in wet and dry periods, and rainwater water samples were collected. Groundwater recharge was calculated by using chemical approaches from the chloride concentrations of the water samples collected. An annual average of 74.84 mm of recharge was found in the Alaehir sub-basin. This value corresponds to 16.38% of annual rainfall. At the same time, it was examined the groundwater and geothermal mixing mechanism to demonstrate the applicability of the Chloride Mass Balance Method. It was concluded that geothermal fluid in Alaehir sub-basin mixed with groundwater at a rate of 17%.Master Thesis 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 CanGroundwater 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.Article Citation - WoS: 3Citation - Scopus: 3A Quality Assessment of Public Water Fountains and Relation To Human Health: a Case Study From Yozgat, Turkey(John Wiley and Sons Inc., 2019) İritaş, Servet Birgin; Türksoy, Vugar Ali; Deniz, Serdar; Koçoğlu, Serhat; Kırat, Güllü; Demirkesen, Ali Can; Baba, AlperPublic fountains are very common and everyday people appreciate the benefits a water fountain can bring. However, consumption of public fountain water in some country has decreased because of growing concerns that constituents in fountain water may have adverse effects on health. A few studies have examined the safety of public fountains, proposing only limited evidence of fountain-related health issues in Turkey. Most of these public fountains are sourced from natural springs in Turkey. In this study, a 177 fountain water and 32 rock samples were analysed for source and quality of water. The geology of the region has the direct impact on the quality of the public fountain water. The results indicate that the level of some elements exceeded the limit values determined by WHO and US.EPA. The most striking high values were observed for iron (Fe), nickel (Ni), aluminum (Al), arsenic (As) and bromine (Br) concentrations.Article Citation - WoS: 5Citation - Scopus: 6Flood Hazard Vulnerability for Settlements of Turkey’s Province of Edirne, Using Aster Dem Data and Landsat-7 Etm+ Image Data(Springer Verlag, 2016) Demirkesen, Ali CanWhile Turkey’s province of Edirne represents one of the country’s most significant cultural heritage areas because it lies in the basins of the Meric and Ergene rivers, this very valuable region is highly susceptible to flooding during heavy rain falls. It becomes particularly vulnerable when neighboring Bulgaria responds to its own threats of heavy rain or snowfall by opening its floodgates of its dams on the River Meric, which flows through the Edirne province. Therefore, for years, the Edirne province has experienced severe floods that are eroding its fertile alluvial agricultural floodplains. An environmental plan based on a determination of the vulnerability levels of the province’s flood hazard risk areas is required if action is taken to alleviate this problem. The objective of this study is to acquire geo-information from the remotely sensed data and to interpret the flood hazard risk levels of the area’s settlements and agricultural floodplains. In this study, the spatial distribution of the flood hazard risk areas in the Edirne province is determined using not only the Advanced Space-Borne Thermal Emission and Reflection Radiometer digital elevation model data of the Edirne province to create maps that illustrate the digital terrain model and the 3D fly-through dynamic model of the study region but also the Landsat-7 Enhanced Thematic Mapper Plus multi-spectral image data set to create land use and land cover types of the study region. The maps exhibit landform characteristics, floodplain topography, and stream drainages. Analysis and interpretation of the maps demonstrate that the areas most susceptible to flooding are Enez, which lies at the northern coastal area of the Aegean Sea and agricultural areas, and the settlements on the Meric River floodplains of Ipsala, Meric, Edirne, and Uzunkopru, listed in decreasing order, respectively.Master Thesis 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 CanAccording 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.Article Citation - WoS: 16Citation - Scopus: 20Groundwater Recharge Estimation Using Hydrus 1d Model in Alaşehir Sub-Basin of Gediz Basin in Turkey(Springer Verlag, 2019) Tonkul, Serhat; Baba, Alper; Şimşek, Celalettin; Durukan, Seda; Demirkesen, Ali Can; Tayfur, GökmenGediz Basin, located in the western part of Turkey constituting 2% land of the country, has an important groundwater potential in the area. Alasehir sub-basin, located in the southeast of the Gediz Basin and subject to the extensive withdrawal for the irrigation, constitutes the study area. Natural recharge to the sub-basin due to precipitation is numerically investigated in this study. For this purpose, 25 research wells, whose depths range from 20 to 50 m, were drilled to observe the recharge and collect the necessary field data for the numerical model. Meteorological data were collected from 3 weather stations installed in the study area. The numerical model HYDRUS was calibrated using the field water content data. Soil characterization was done on the core samples; the aquifer characterization was performed, and the alluvial aquifer recharge due to precipitation was calculated. As a result, the computed recharge value ranges from 21.78 to 68.52 mm, with an average value of 43.09 mm. According to the numerical model, this amount of recharge corresponds to 10% of the amount of annual rainfall.Article Citation - WoS: 9Citation - Scopus: 12Compositing Climate Change Vulnerability of a Mediterranean Region Using Spatiotemporally Dynamic Proxies for Ecological and Socioeconomic Impacts and Stabilities(Springer Verlag, 2017) Demirkesen, Ali Can; Evrendilek, FatihThe study presents a new methodology to quantify spatiotemporal dynamics of climate change vulnerability at a regional scale adopting a new conceptual model of vulnerability as a function of climate change impacts, ecological stability, and socioeconomic stability. Spatiotemporal trends of equally weighted proxy variables for the three vulnerability components were generated to develop a composite climate change vulnerability index (CCVI) for a Mediterranean region of Turkey combining Landsat time series data, digital elevation model (DEM)-derived data, ordinary kriging, and geographical information system. Climate change impact was based on spatiotemporal trends of August land surface temperature (LST) between 1987 and 2016. Ecological stability was based on DEM, slope, aspect, and spatiotemporal trends of normalized difference vegetation index (NDVI), while socioeconomic stability was quantified as a function of spatiotemporal trends of land cover, population density, per capita gross domestic product, and illiteracy. The zones ranked on the five classes of no-to-extreme vulnerability were identified where highly and moderately vulnerable lands covered 0.02% (12 km2) and 11.8% (6374 km2) of the study region, respectively, mostly occurring in the interior central part. The adoption of this composite CCVI approach is expected to lead to spatiotemporally dynamic policy recommendations towards sustainability and tailor preventive and mitigative measures to locally specific characteristics of coupled ecological–socioeconomic systems.Master Thesis Archiving of the Conservation Data of Immovable Cultural Assets Dating To 1300-1600 in Urla Center Using Gis(Izmir Institute of Technology, 2019) Yönder, Veli Mustafa; Turan, Mine; Demirkesen, Ali CanThis study aims to create a digital archiving system of immovable cultural assets belonging to the early Turkish time frame in Urla historic center. Forming a database with the assistance of the Geographic Information System (GIS) to comprehend and assess the life stories of monuments and to access various user profiles is also considered. In the methodology section; academic articles, books, journals, personal archives, data acquired from state institutions or architectural offices, and the data obtained during fieldwork (physical status and interviews with users) were processed in a GIS platform. Academic reviews and researches of the buildings were conducted. In the decision-making process, which is a sophisticated and multidimensional process, the share of conservation data and data management in the whole process becomes progressively significant. Documentation and registration of architectural immovable cultural assets, which is one of the important figures in the urban context, are conducted under the supervision of the Regional Directorate of Pious Foundations or the Conservation Board. Therefore, extracting a large number of mass data produced each year and making the required classifications make assist decision-making processes. In the discussion and results part, analysis and comparative study of all conservation data of the cultural assets were performed. The results for constructing the database are understanding the scope, accessibility, developers, scale, and data types. In the results for the conservation data archived: are understanding historical background, physical characteristics, conservation activities, and interpreting conservation decisions about buildings.Article Citation - WoS: 4Digital Terrain Characterization and Interpretation of Lake Van Region for Earthquake Vulnerability Combining Remote Sensing and Geographical Information Systems(Parlar Scientific Publications, 2017) Demirkesen, Ali Can; Evrendilek, FatihThe Lake Van basin and its surroundings (36,500 km(2)) in the eastern Turkey have not been investigated adequately in terms of earthquake vulnerability, and pre-earthquake preparedness. In this study, a digital terrain model (DTM) of the Lake Van region was developed combining an ASTER digital elevation model (DEM), Landsat-7 ETM+ imagery, remote sensing techniques, and geographical information systems. Terrain characteristics derived from DTM with DEM, and a 3-D land-use and land-cover fly-through view such as fault zones, drainage patterns, lineaments, and landforms were interpreted in terms of earthquake vulnerability. Our results indicate that the directions of Mus-Tatvan (Mus thrust), Bitlis thrust, and ErcisPatnos-Malazgirt-Varto-Karliova along with Van and Ercis possess the highest risk of earthquake hazards.Master Thesis Gis-Based Determination of Suitable Areas With Multi-Criteria Approach for Solar Power Plants and Assessment of Land Decisions: the Case Study of İzmir(01. Izmir Institute of Technology, 2021) Toprakcı, Nevin Selin; Demirkesen, Ali CanThe 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.
