Even though water-energy systems and ecosystems have complex relationships, regional energy policies seldom con-sider this connection. The current regional energy policies are developed primarily based on technical and socio-economical aspects and lack ecological considerations that may deteriorate the ecosystems and sustainability of these policies. Hence, considering the water-energy-ecosystem nexus in the development stage of the energy policies can aid decision-makers in initiating successful multi-dimensional energy policies. This study proposes a novel ap-proach to develop an environmental index to support the regional energy policies that rely on Run-of-river (RoR) hy-droelectric power plants (HEPPs) with a nexus approach. First, significant environmental impacts of RoR HEPPs are identified as environmental flows, impacts on ecologically valuable areas such as heritage sites, wetlands, national parks, river water quality degradation, modification of habitat, and impact on ecosystems and biodiversity loss. Then these impacts are represented through indicators and are aggregated into an overall environmental performance index through a fuzzy multi-criteria decision-making approach. The proposed approach allows the integration of eco-logical dimensions into the evaluation of RoR HEPPs through easy-to-measure indicators, among which environmental flow is a critical component.

Evaluation of potential run-of river hydropower plant sites using multi-criteria decision making in terms of environmental and social aspects
Temel, Pelin; Alp, Emre; Department of Environmental Engineering (2015)
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...
Development of a climate risk assessment method for the provinces of Turkiye
Bütün Bayındır, Gülsün Duygu; Yetişkul Şenbil, Emine; Department of City and Regional Planning (2022-8-25)
Climate change is disproportionately threatening vulnerable systems and amplifying existing risks. Considering the increasing impacts of climate change, assessing climate-related risks and identifying respective critical vulnerabilities have gained vital importance in addressing climate change. This thesis aims at examining the climate risk and vulnerability levels of provinces by conducting a climate risk and vulnerability assessment at the national scale provincial level to respond to the immediate climat...
A METHOD FOR TECHNICAL ECONOMIC-ANALYSIS OF SOLAR HEATING-SYSTEMS
TASDEMIROGLU, E; ARINC, F (Elsevier BV, 1988-01-01)
The necessity for technical-economic analysis of solar energy systems is obvious when assessing their feasibility vis-á-vis conventional alternative systems. Optimum magnitudes of the installation parameters should be defined under the required economic conditions. In this study, the optimization procedure was chosen so as to maximize the total accumulated saving throughout the economic lifetime of the system. The annual solar heating fraction of the system is assessed using the f-chart method which can be ...
Probabilistic modeling of operational dynamic water balance system for a mining facility
Pelenk, Ümit Giray; Yılmaz, Koray K.; Department of Geological Engineering (2019)
Water management in any environment is quite difficult and complex not only because of the effort that is required to comply with the environmental regulations but also due to the dynamic nature of the system not well suited for the deterministic approaches. As a result, probabilistic approaches are developed to make decisions that can actually represent the uncertainties quantitatively as probability distributions. Such methods, considered to be the best practice in mining industry, are very useful to make...
Application of non-market economic valuation method to value the environmental benefits of geothermal energy in monetary terms
Horasanlı, Erol; Alp, Emre; Department of Environmental Engineering (2010)
Determining environmental economic benefits of geothermal energy is difficult since there is no market for all environmental goods and services related to it. In order to determine and measure the market price of non-market goods and services, non-market valuation methods are used. Since intangible benefits do not have monetary values, non-market valuation techniques are applied to estimate them. Non-market valuation methods are important tools for policy makers in the cost and benefit analysis and environm...
