Evaluation of potential run-of river hydropower plant sites using multi-criteria decision making in terms of environmental and social aspects

Temel, Pelin
Electrical energy is an indispensable need of continuity of life in today’s world. Therefore energy generation sources are one of the most important topics of countries, so that every country develops a strategy to use them efficiently. At this point, necessity of involving sustainability of energy sources in strategies makes hydropower energy become prominent. On the other hand, rapid increase in number of hydropower projects causes losing control of environmental effects of them. In this sense, a decision making methodology including environmental and social evaluation of run-of river hydropower plants is developed in the content of this study. In the scope of the study multi-criteria decision making (MCDM) analysis is used as decision making tool. For the MCDM analysis, ten environmental and social criteria are determined; for the aggregation of these criteria “and”, “or”, “Ordered Weighted Averaging” (OWA) and “Linear Weighted Averaging” (LWA) methods are used. Developed methodology is applied on five hydropower plants in Artvin/ Şavşat. Case study showed that “and” and “or” aggregation methods do not give chance to compare results and make no contribution to decision making process while OWA and LWA methods give useful results. Also, according to the case study implementation Gana is the most acceptable hydropower plant among five selected projects while Armutlu is the least acceptable one. Acceptability results of the case study implementation areas change between 0.17 and 0.72.


Identification of management strategies and generation factors for spent lead acid battery recovery plant wastes in Turkey
Çelebi, Sarp; Yetiş, Ülkü; Ünlü, Kahraman (SAGE Publications, 2019-03-01)
The recovery of spent or waste lead acid batteries is important both for the management of lead input to the environment and to meet the lead demand of the market in a more energy and cost effective manner than primary production. As an important producer of lead acid batteries for the Middle Eastern and Eastern European market, Turkey seems to meet 22%-52% of its total lead demand by waste lead acid battery recovery. In this study, the wastes from Turkish waste lead acid battery recovery plants are identif...
Predicting Diel, Diurnal and Nocturnal Dynamics of Dissolved Oxygen and Chlorophyll-a Using Regression Models and Neural Networks
Human-induced and natural interruptions with continuous streams of observational data necessitate the development of gap-filling and prediction strategies towards better understanding, monitoring and management of aquatic systems. This study quantified the efficacy of multiple non-linear regression (MNLR) versus artificial neural network (ANN) models as well as the temporal partitioning of diurnal versus nocturnal data for the predictions of chlorophyll-a (chl-a) and dissolved oxygen (DO) dynamics. The temp...
Identification of waste management strategies and waste generation factors for thermal power plant sector wastes in Turkey
Demir, Cansu; Yetiş, Ülkü; Ünlü, Kahraman (SAGE Publications, 2019-03-01)
Thermal power plants are of great environmental importance in terms of the huge amounts of wastes that they produce. Although there are process-wise differences among these energy production systems, they all depend on the logic of burning out a fuel and obtaining thermal energy to rotate the turbines. Depending on the process modification and the type of fuel burned, the wastes produced in each step of the overall process may change. In this study, the most expected process and non-process wastes stemming ...
Bioelectricity Generation From Wastewater Sludge Using Microbial Fuel Cells: A Critical Review
Ömeroğlu, Seçil; Sanin, Faika Dilek (Wiley, 2016-09-01)
Today, the majority of the world's energy is provided by fossil fuels. Natural energy resources soon will be consumed as a result of rising energy needs of the growing population, leading to a global energy crisis. The insecurity in the energy market also affects the global economy negatively and forces the governments to investigate renewable energy alternatives such as bioenergy. Bioenergy technologies can reduce greenhouse gas (GHG) emissions significantly and can serve to satisfy many forms of energy de...
Assessing the effects of wind farms on soil organic carbon.

Wind energy is considered one of the cleanest and most sustainable resources among renewable energy sources. However, several negative environmental impacts can be observed, unless suitable sites are selected for the establishment of wind farms. The aim of this study is to determine the change in the soil organic carbon (SOC) stock resulting from land cover changes that were caused by wind farm establishments in the Karaburun peninsula. Within the scope of the study, remote sensing and geographic informatio...
