GIS based geothermal potential assessment: A case study from Western Anatolia, Turkey

Potential geothermal areas are identified through investigation of spatial relations between geothermal occurrences and their surrounding geological phenomena in western Anatolia, Turkey. The identification is based on only publicly available data. It is expected that the study will guide further preliminary investigations performed for large areas having limited information. Magnetic anomaly, Bouger gravity anomaly, earthquake epicenter and lineament datasets are used for the analysis. The first is used without any modification whereas the rest are utilized to extract three evidence maps: distance to major grabens, Gutenberg-Richter b-value and distance to lineaments, respectively. Predictor maps are produced from these evidence maps as well as from the unprocessed magnetic anomaly map by applying two different binarization procedures. From each binarization procedure a favorability map is produced separately using Index Overlay (IO) and Weights of Evidence (WofE) methods. The findings reveal that weighting predictor maps according to spatial association between evidence maps and training points lead to more accurate prediction in both WofE and IO methods. The potential areas in the final maps are Aydin, Denizli, Manisa, Balikesir and Kutahya of which first two have been explored and exploited, and thus found to be favorable, while the rest are nearly unexplored.


Geothermal energy potential and utilization in Turkey
Taşdemiroğlu, Ersoy (Elsevier BV, 1988-3)
The regional distribution of the geothermal energy potential in Turkey, recent surveys, and utilization areas are described. The present and future roles of geothermal energy and their economic aspects are discussed. The implications of geothermal energy exploration and utilization are noted. Recommendations are made to expand geothermal-energy development.
Estimation of total solar radiation from bright sunshine hours in Turkey
Taşdemiroğlu, Erol; Sever, Rita (Elsevier BV, 1989-12)
Measurements of total solar radiation and bright sunshine hours in six different climatological locations in Turkey are used to develop an Angstrom type equation. The coefficients are found for a linear equation from regression analysis for these locations. A simple overall equation, which yields the solar radiation in any location in Turkey for bright sunshine hours, is developed. The results of this equation, together with the results obtained from five similar, internationally accepted correlations, are ...
Theoretical study of solar ponds for space heating in diverse climatic conditions of Turkey
Taşdemiroğlu, Erol (Elsevier BV, 1988-11)
The thermal performance of a solar pond operating under steady-state conditions is analysed theoretically for use in space heating in four diverse Turkish locations having widely different climates. The average pond temperature for each month is obtained for maximum heat extraction, with the thickness of the pond-insulating layers as a fixed parameter. For a fixed pond-insulating layer, the useful heat withdrawn during the month is calculated for these four locations. Space-heating loads and the solar heati...
Hydroelectric power potential and its use in Turkey
Taşdemiroğlu, Erol (Elsevier BV, 1988-7)
Hydroelectric development in Turkey is briefly reviewed. The results of estimates of gross and economically exploitable hydroelectric power potentials are compared. Dam sites and their order for construction are identified. Present and future developments in the power sector are analyzed and projections are given for electricity consumption and production to the year 2010. Hydraulic, thermal and nuclear contributions to total electricity generation are discussed. Finally, problems associated with hydroelect...
GIS based geothermal potential assessment for Western Anatolia
Tüfekçi, Nesrin; Süzen, Mehmet Lütfi; Department of Geological Engineering (2006)
This thesis aims to predict the probable undiscovered geothermal systems through investigation of spatial relation between geothermal occurrences and its surrounding geological phenomenon in Western Anatolia. In this context, four different public data, which are epicenter map, lineament map, Bouger gravity anomaly and magnetic anomaly maps, are utilized. In order to extract the necessary information for each map layer the raw public data is converted to a synthetic data which are directly used in the analy...
