Turkey's population is constantly increasing, and thus, the energy consumption is also increasing. Wind turbines, nuclear power plants, and boron and uranium resources are used for energy needs. Turkey meets its energy needs using these resources. Sun which is a natural and unlimited resource among these resources is one of the most important natural energy resources. The most important issue to consider in order to utilize solar energy in the most efficient way and to obtain advantages is the selection of the suitable place for solar plants. The aim of this study is to select the most suitable location for solar energy plants and provide to build solar power plants in suitable places. Eleven data layers (sunshine duration, solar radiation, slope, aspect, road, water sources, residential areas, earthquake fault line, mine areas, power line and transformers) that were prepared using analytical hierarchy process (AHP) method in GIS were used and analysed. Based on the results of the analysis, the location of the areas where solar energy could be built was selected. As a result of the study, it was determined that in particular the north-east of the Nigde is the most suitable for solar plants. Ulukisla district has the most suitable feature for solar plants among the Nigde districts. 80% of the existing solar plants are located in the detected areas. It has been determined that the other 20% of the solar plant is also in the suitable areas, but their location is not suitable for the most efficiency.
In the study, the temporal change analysis of Akkaya Reservoir in Niğde was made. The Reservoir was established in 1964. The change of reservoir between 1999, 2009 and 2019 was analyzed using remote sensing method. Satellite images used in the study belong to August (1999, 2009, 2019). MNDWI (Modified Normalized Difference Water Index) analysis was used. With the results of this analysis; the amount of water surfaces in the reservoir basin was calculated by years. After this analysis, NDVI (Normalized Difference Vegetation Index) analysis was used and land cover types were determined by CORINE. It has been determined that the water surface map of 2009 covers a larger area compared to other years. When only the area where the reservoir is located is evaluated by the polynomial equation (2nd degree), there may be a decrease of approximately 26% in the reservoir water surface area within 15 years. As a result of the study, it has been determined that Landsat satellite data can be used to determine the water surface amounts. If study in smaller areas will be done, use the lower resolution satellite images are suggested. In this study, MNDWI analysis was found more successful than NDVI analysis to find water surface area. Multi-band satellite images provide important qualitative information in evaluating the functions used in ecosystem-based planning studies.
The subject of the study is to evaluate the Niğde Akkaya Dam with SWOT analysis and to make recommendations in terms of recreational use. The aim of the study is to identify the strengths and weaknesses, threats and opportunities of the Akkaya dam and to determine its goals and strategies in terms of recreation. In line with this purpose, the socio-economic, cultural and natural features, landscape potential of the area were evaluated using the SWOT, the opportunities that the positive and negative aspects of the area, were presented, and the possible or existing threats were determined. At the same time, the current recreation potential of the dam was determined, and suggestions were developed in line with the data in order to offer alternatives that can be evaluated in terms of sustainable use of the areas. It was determined that pollution occurs in the dam water due to environmental wastes, as a result of this pollution, harmful creatures multiply and bad smells are formed. However, it is accepted that the dam is home to a large number of migratory birds, that it has not lost its naturalness, and that most of the dam is in the university campus. Threats to the dam are; low water level, fishing, duck hunting etc. damage to ecological life due to activities, smell gradually increased. Their opportunities are determined as providing a suitable environment for bird watching, having a suitable infrastructure for ecological research, and being suitable for recreational activities for water. At the end of the study, suggestions were developed in terms of suitability of Akkaya Dam for recreational activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
