Conference Object A Decision Support System for Assessment of Land-Use Changes, the Case of Izmir(LookUs Scientific, 2013) Yazdani, Hamidreza; Saygın, Mustafa Ömür; Saygın, Ömür; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyLand-Use changes and their possible impacts over time as consequences of proposed urban developments are one of main concerns of planners in planning process. Understanding the impact of these changes on environment is a crucial issue in the planning approach aims to achieve the sustainable urban development. A Planning support system (PSS) is mainly based on collecting, monitoring, analysing data and evaluating the impacts of alternative planning scenarios using Geographical Information Systems (GIS) This paper offers an approach to evaluate the interoperability of a model based on the data sets to be explored. Considering the integration of satellite imagery, field survey and plans where adequate local data set is missing and modifying the model to evaluate best represented data increase reliability of a model. For this propose this study modifies "ESRI Smart Land-Use model (LUCIS)" for the data represented region meanwhile integrates the data sets for the most accurate representation This model based on best presented data provides crucial decision guidelines for decision makers in testing development scenarios. Different PSS's have different algorithms and underlying assumptions. Consequently Comparing results of several PSS (ie. CommunityViz, What-If) for the same purpose could be more reliable than testing a single model in a project Further research should be conducted via web-based monitoring system that would improve collaboration of different interest groups.Article Citation - WoS: 40Citation - Scopus: 44Geological and Hydrogeochemical Properties of Geothermal Systems in the Southeastern Region of Turkey(Elsevier Ltd., 2019) Baba, Alper; Şaroğlu, Fuat; Baba, Alper; Özel, Nedret; Yeşilnacar, Mehmet İrfan; Demir, Mustafa Muammer; Demir, Mustafa Muammer; Gökçen Akkurt, Gülden; Uzelli, Taygun; Dursun, N.; Uzelli, Taygun; Yazdani, Hamidreza; 03.03.

Izmir Institute of Technology; 03. Faculty of EngineeringThe Anatolia region is one of the most seismically active regions in the world. It has a considerably high level of geothermal energy potential thanks to its geological and tectonic settings. The Southeastern Anatolia Region (GAP) is located in the south of Bitlis-Zagros Suture Zone (BZSZ) which is in the Arabian foreland. During the neotectonic period, the folded structures have been developed under the influence of tectonic compression from the Upper Miocene in the GAP Region where it is closely related to active tectonics. These tectonic activities produce more geothermal resources. Few studies have been carried out in this region for geothermal energy. Limited portions of the geothermal resources have been used both for thermal tourism and greenhouses in the GAP region. The aim of this study is to determine geological, tectonic and hydrogeochemical properties of a geothermal system in the GAP Region. The result indicates that the surface temperatures of geothermal fluids are from 20 to 84.5 °C A large number of abandoned oil wells, whose temperature reaches 140 °C, are found in the region. Also, hydrogeochemical results show that deep circulated geothermal fluids are enriched with Na-Cl and shallow geothermal system fluids have Na−HCO 3 and Ca-SO 4 characters because of cold water mixing and water-rock interaction. Cold waters are generally of Ca-Mg−HCO 3 and Ca−HCO 3 type. Cation geothermometers were used for determining reservoir temperature of the geothermal resources in the region. The results show that the reservoir temperature of these geothermal resources ranges from 50 °C to 200 °C. The isotope data (oxygen-18, deuterium and tritium) suggests that geothermal fluid is formed by local recharge and deep circulation.
