    Climatic identity assessment of the climate change
    (Inderscience Enterprises Ltd, 2013) Toprak, Z. Fuat; Hamidi, Nizamettin; Toprak, Sahin; Sen, Zekai
    In the last few decades, due to the potentially serious impacts upon the atmosphere, earth, and ocean the climate change issue become internationally disputable subject among many scientists including various specialists such as climatologists, atmospheric researchers, oceanographers, hydro-meteorologists, agriculturalists, in particular, local administrators in addition to politicians, as well as the people at different aspects of the life. The main goal of this study is to present a review on global climate change with various dimensions. In order to determine and follow the existence and the local impacts of global climate change for any country or region, reliable data are needed essentially in a comparative, illustrative, and visual format. For an effective basis, it is appropriate to use internationally recognised scenarios in addition to national linguistic (verbal) as well as numerical data and a common format for the meteorological observations and measurements. Therefore, it is another aim of this paper to provide an extensive but crisp review about the climate change by considering 'climatic identity' concept concerning which information should be reported in the commonly formatted records.

    Hydroelectric Energy Potential of Turkey: A Refined Calculation Method
    (Springer Heidelberg, 2016) Alashan, Sadik; Sen, Zekai; Toprak, Z. Fuat
    Turkey is one of the countries with high hydroelectric energy potential, but today only 35% of this potential is functional. This is due to its geographic position at subtropical climate region with upstream of Euphrates-Tigris Basin. In general, classical calculation methodologies are used for hydropower potential assessments. This paper explains the hydroelectric energy policy and potential of Turkey and suggests a more refined calculation method on the basis of hypsographic curve. Furthermore, currently used hydropower potential calculation formulations are revised in detail, and a new calculation method referred to as the energy tree (ET) is explained and applied to actual data from upper Euphrates River main branch, the Murat River. Comparison of the numerical results in terms of relative error indicates that ET yields about 0.4% improvement over the DP and about 6.5% over the SP methods. This means that ET method yields better refined results than the existing methodologies.
