Öğe Comparison of designed different land reallocation models in land consolidation: A case study in Konya/Turkey(ELSEVIER SCI LTD, 2015) Uyan, Mevlut; Cay, Tayfun; Inceyol, Yasar; Hakli, HuseyinLand consolidation (LC) is the most favorable land management approach for solving agricultural land degradation. LC is essential for ensuring the economic viability of rural areas, facilitating environmental management, or rationalizing urban growth. LC projects consist of various steps. Land reallocation is the most important stage of LC studies and a tool which rearranges proprietary rights. For fast and efficient progress in projects, usage of computer technology has been essential. In this case study, designed two different land reallocation models (SDSS-based and GA-based land reallocation models) is compared for LC projects in reallocation of newly created regular size parcels to landowners. As a result of these comparisons, the GA-based model is some successful than the SDSS-based model in terms of average parcel size, number of parcels and average number of parcels per land-owner. The benefits derived from both models are much higher than conventional models. (C) 2014 Elsevier B.V.

The success of LC projects depends on the correct determination of soil index (SI) for each of the agricultural parcel. SI values for all study area are determined by interpolation methods using observed SI plots. The spatial analysis based on the kriging method is a convenient and strong way for the estimation of the unknown points from the known points. The purpose of this study was to determine and evaluate the agricultural SI using ordinary kriging with GIS technology for LC projects. Spatial continuity of SI values was calculated using an experimental variogram. The performance of six models (Circular, Spherical, Tetraspherical, Pentaspherical, Exponential, Gaussian) have been compared. Spatial structure of SI values was better explained using exponential models. Nugget-sill rate can be used in the classification of the spatial dependency. The nugget-sill ratio was showed high dependency with 0.21. The average range of variogram (exponential model) for the spatial analysis is about 5815 m. Results of ordinary kriging for SI values were underestimated by 11%. The estimations obtained for SI were represented in a map. The results of the ordinary kriging based SI values were compared with the results of the prepared SI map by classical methods for some agricultural parcels. (C) 2016 Elsevier B.V.

Citizen's demands and city manager's decisions important factors in transportation planning but the other important factors; city's and citizen's characteristic features. Relational structure to be determining between spatial and network analysis with these features, according to these situation necessary making transtportation policies. The purposes of this paper are to determinate of transportation networks base on the optimal public transportation polices using spatial and network analysis methods of an urbanized city: Konya, Turkey.Öğe Evaluation of reallocation criteria in land consolidation studies using the Analytic Hierarchy Process (AHP)(ELSEVIER SCI LTD, 2013) Cay, Tayfun; Uyan, MevlutLand consolidation (LC) can be described as the rearrangement of land areas according to developing agricultural technology. Land reallocation is the most important phase of LC. The reallocation process is a legal obligation in Turkey which takes into account landowners' preferences. First, the planner determines these preferences at interview. These interviews should be performed very carefully, because they are a tool for rearranging property rights. In this study, preferences for reallocation process were determined with the Analytic Hierarchy Process (AHP). The results of an AHP-based land reallocation model were compared with the results of an interview-based land reallocation model, which is the classical model. According to the results, 62.7% of the participants were pleased with the interview-based land reallocation model, and 91.5% with the AHP-based land reallocation model. (C) 2012 Elsevier Ltd.

In Turkey, solar energy investments have been developed rapidly in recent years. Site selection for solar farms is a critical issue for large investments because of quality of terrain, local weathering factors, proximity to high transmission capacity lines, agricultural facilities and environmental conservation issues. Multi criteria evaluation methods are often used for different site selection studies. The purpose of this study was to determine suitable site selection for solar farms by using GIS and AHP in the study area. The final index model was grouped into four categories as "low suitable", "moderate", "suitable" and "best suitable" with an equal interval classification method. As a result, 1538% (928.18 km(2)) of the study area has low suitable, 14.38% (867.83 km(2)) has moderate suitable, 15.98% (964.39 km(2)) has suitable and 13.92% (840.07 km(2)) has best suitable for solar farms area. 40.34% (2434.52 km(2)) of the study area is not suitable for solar farm areas.

Landfill site selection process aims to locate the areas that will minimize hazards to the environment and public health. Multi-criteria evaluation methods are often used for different site selection studies. The purpose of this study was to determine suitable landfill site selection by using the geographical information system and the analytic hierarchy process in the study area. The final index model was grouped into four categories as "low suitable", "moderate", "suitable" and "best suitable" with an equal interval classification method. As a result, 12.69 % of the study area was low suitable, 7.27 % was moderately suitable, 13.79 % was suitable, and 15.52 % was the best suitable for landfilling; 50.72 % of the study area is not suitable for a landfilling.Öğe Optimal site selection for solar power plants using multi-criteria evaluation: A case study from the Ayranci region in Karaman, Turkey(SPRINGER, 2017) Uyan, MevlutCurrently, coal, oil and natural gas are mainly used for energy in most countries. These sources, called fossil fuels, are not renewable. Fossil fuels are limited, and their reserves are steadily decreasing. This situation causes the prices to rise constantly. On the contrary, renewable energy is clean, economical and unlimited. Turkey has a very high potential for renewable energy, and the Turkish government has made significant reforms for solar energy investments over the last decade. Site selection for solar power plants is a critical issue for large investments because of quality of terrain, local weathering factors, proximity to high transmission capacity lines, agricultural facilities and environmental conservation issues. Multi-criteria evaluation is a tool that allows one to choose the best criterion among multiple and offer a structure with a wide range of applications. In this paper, the ideal locations for solar power plant were selected using the geographic information system and analytic hierarchy process which is one of the multi-criteria evaluation methods. The resulting land suitability was grouped into three categories: low suitable, suitable and best suitable using an equal interval classification method. Consequently, 15,550 ha or 6.23% of the evaluated region was determined as the best suited areas for solar power plants.Öğe Social texture map and Social Information Center design and integration for social welfare in the city of Konya, Turkey(SAGE PUBLICATIONS LTD, 2017) Osmanli, Nurullah; Sert, Emra; Uyan, MevlutMetropolitan municipalities are responsible for social services in Turkey. This study is built on two main points that affect each other: (1) the creation of a social texture map with the help of Geographic Information Systems (GIS) and (2) the establishment of a Social Information Center (SIC) in the city of Konya, Turkey, within the scope of Konya Metropolitan Municipality. The SIC Project includes the relation of the local government services to the public and can be described as an important project. As the scope of this project is conceived on a model scale of Konya Province, it includes important steps where inferences can be made on the scale of Turkey.Öğe Spatial analyses of groundwater level differences using geostatistical modeling(SPRINGER, 2013) Uyan, Mevlut; Cay, TayfunThe purpose of this study was to determine and evaluate the spatial changes in the depletion of groundwater level differences by using geostatistical methods based on data from 58 groundwater wells during the period from April 1999 to April 2008 in the study area. Geostatistical methods have been used widely as a convenient tool to make decision on the management of groundwater levels. To evaluate the spatial changes in the level of the groundwater, geographic information system is used for the application of universal kriging method with cross-validation leading to the estimation of groundwater levels. The resulting prediction mappings identify the locations of groundwater level fluctuations of the study area. The average range of variogram (spherical model) for the spatial analysis is about 9,200 m. Results of universal kriging for groundwater level differences drops were underestimated by 15 %. Cross-validation errors are within an acceptable level. The maps show that this area of high decrease of groundwater level is located at the southwest. Kriging model helps also to detect sensitively risk prone areas for groundwater withdrawing. Such areas must be protected with an effective management procedure for future groundwater exploitations.Öğe Spatial and Temporal Groundwater Level Variation Geostatistical Modeling in the City of Konya, Turkey(WILEY, 2009) Cay, Tayfun; Uyan, MevlutGroundwater is one of the most important resources used for drinking and utility and irrigation purposes in the city of Konya, Turkey, as in many areas. The purpose of this study is to evaluate spatial and temporal changes in the level of groundwater by using geostatistical methods based on data from 91 groundwater wells during the period 1999 to 2003. Geostatistical methods have been used widely as a convenient tool to make decisions on the management of groundwater levels. To evaluate the spatial and temporal changes in the level of the groundwater, a vector-based geographic information system software package, ArcGIS 9.1 ( Environmental Systems Research Institute, Redlands, California), was used for the application of an ordinary kriging method, with cross-validation leading to the estimation of groundwater levels. The average value of variogram (spherical model) for the spatial analysis was approximately 2150 m. Results of ordinary kriging for groundwater level drops were underestimated by 17%. Cross-validation errors were within an acceptable level. The kriging model also helps to detect risk-prone areas for groundwater abstraction. Water Environ. Res., 81, 2460 (2009).
