    Innovative trend analysis of total annual rainfall and temperature variability case study: Yesilirmak region, Turkey
    (Springer Heidelberg, 2019) Serencam, Ugur
    It is well known that any kind of ordinary hydrometeorological parameter trend may have increasing or decreasing tendency systematically. Various methodologies are developed for possible trend identification such as the well-known Mann-Kendall test and recently Sen innovative trend analysis (ITA) approaches. The former has a set of assumptions, whereas the latter is almost without any restrictive assumption. The main purpose of this paper is to present precipitation and temperature trend behaviors by applying ITA in Yesilirmak drainage basin. Selected observation stations are mainly located at the Black Sea confluence region of Yesilirmak while few others at the middle and upper drainage basins. ITA provided visual inspection with quantitative trend slopes distinctively for low, medium, and high sub-levels with physical interpretations. Based on categorization, precipitation records have significant decreasing trends in low, medium, and high levels as an average - 3.4%, - 3.8%, and - 2.4%, respectively. In contrary to precipitation trend, and consistent to global expectation in climate change, temperature records have significantly strong increasing tendency along the basin. In sub-level of temperature, this strong trend tendencies are detected + 4.6%, + 4.8%, and + 7.2% from low to high ranges, respectively.

    RENEWABLE ENERGY STATUS AND HYDROPOWER IN SOME DEVELOPING COUNTRIES AND FOCUS ON TURKEY
    (Parlar Scientific Publications (P S P), 2016) Yuksel, Ibrahim; Arman, Hasan; Serencam, Ugur; Songur, Mehmet; Demirel, I. Halil
    The share of renewable energies varies quite a lot in the developing countries, both in terms of total primary energy and electricity generation. Several different policy instruments are in use for promoting renewable energies, such as quota obligations, price subsidies, and taxes/tax exemptions on energy. Some countries such as Turkey, also have specific political programs for renewable energies. The obstacles and success conditions mainly deal with geographical, economic, administrative and political factors. The Republic of Turkey forms a natural bridge between Europe and Asia and the country has a relatively young population in both Europe and Asia. Turkey aims to utilize its energy potential, including from renewable sources, in a cost-effective manner In its efforts to promote renewable energy, the government has focused on electricity, but has recently started to pay more attention to heat. On the other hand, Turkey's geographical location has several advantages for extensive use of most of the renewable energy sources. In this regard, renewable energy resources appear the most efficient and effective solutions for clean and sustainable energy development in Turkey. In addition to Turkey has a great hydropower, especially small hydropower potential. This paper deals with Turkey's renewable energy status in developing countries.
