Computational modelling of free surface flow in intake structures using flow 3D software

Ergen, Mehmet Kayra
Turkey is a developing country and its energy demand is increasing due to its growing population and industry. As a result, to fulfill this growing energy demand, Turkey is currently developing its unused hydropower potential, especially through small hydroelectric power plants (SHPPs). Estimation of annual electricity generation of a small hydropower plant strongly depends on streamflow data. In Turkey, there are a limited number of streamgaging stations so the estimation of streamflow at a potential SHPP location requires transferring streamflow time series from a reference streamgaging station to the ungaged basin. In order to determine daily streamflow time series for ungaged catchments, typically the nearest streamgaging station is chosen as the reference streamgaging station. However the distance between a reference streamgaging station and an ungaged catchment may not always be the most appropriate reference streamgaging station selection criterion. Archfield and Vogel (2010) proposed a new method called the Map Correlation Method (MCM) to select a reference streamgaging station to donate its observations to an ungaged catchment. MCM aims to identify the most correlated streamgaging station with the ungaged catchment. This new method is used at the Western Blacksea Basin in Turkey to select the best among possible reference streamgaging stations. The method proved to be promising; the most correlated streamgaging station for approximately one third of the study streamgaging stations are identified correctly by the MCM.


Modeling of gas demand using degree-day concept: Case study for Ankara
Gumrah, F; Katircioglu, D; Aykan, Y; Okumus, S; Kilincer, N (2001-02-01)
The demand for natural gas is rapidly increasing in Turkey as it is in the rest of the world. However, natural gas reserves and production are rather limited in Turkey. The bulk of the Turkish gets demand is met by imports. Russia currently accounts for 69% of Turkey's gas supplies. Physical shortages might occur; supplies for industrial production and household consumption could temporarily run short. Also, fluctuations in consumption might occur due to climatic reasons or peak daily industrial energy dema...
Balkusan Dam and HEPP : investigation of better alternatives to EİEİ formulation
Çetinkaya, Mehmet Akın; Kentel Erdoğan, Elçin; Department of Civil Engineering (2013)
Due to the economic and social growth of Turkey, there is a rapid increase in energy demand. Turkey does not have sufficient natural gas and petroleum reserves; however, it has large hydropower potential. Hydropower is the most widely used form of renewable energy. To generate electricity between elevations 1500 m and 450 m on Balkusan Creek, General Directorate of Electrical Power Resources Survey and Development Administration (EIEI) conducted a feasibility study for a hydroelectric power plant (HEPP) com...
Challenges to Turkey’s Transition to a Low-Carbon Urban Development: A Roadmap for an Effective Climate Change Policy
Balaban, Osman (Springer, 2019-02-01)
Turkey is an emerging economy with a growing gross domestic product, which brings with it a rapid increase in energy consumption. Turkey’s per capita GHG emissions increased from 3.88 tons of CO2eqin 1990 to 6.07 tons of CO2eqin 2015. Furthermore, due to being located in the Mediterranean Basin, Turkey is highly vulnerable to such impacts of climate change as temperature rises, flooding and water shortage. Since the early 2000s, there have been several efforts in developing a climate policy in Turkey. The E...
Safety assessment of limestone-based engineering structures to be partially flooded by dam water: A case study from northeastern Turkey
GÖKÇEOĞLU, CANDAN; Türer, Ahmet; Nefeslioglu, H. A.; TÜRER, DİLEK; Akgül, Çağla (2016-07-15)
Turkey has been faced with an escalating energy demand and recurring droughts within the last few decades. The construction of the BAGISTAS 1 Hydroelectric Power Plant Dam, one of the dams constructed in order to solve these problems, resulted in the partial submersion of a number of pre-existing railway bridges and retaining walls of the Divrigi-Ilic-Erzincan Railway System (NE Turkey). Before the accumulation of dam water, the structural safety of these 86-year-old infrastructures, which were constructed ...
Optimisation of the Tigris river hydropower system operations
Yalçın, Emrah; Tiğrek, Şahnaz; Department of Civil Engineering (2015)
Growing external energy dependence and rising oil prices are encouraging Turkey to turn to renewable energy, especially hydropower. The amended legislation on the transference of the operational rights of existing, under-construction and planned hydropower plants to the private sector and the allocation of water right licenses to develop new projects for electricity production has led to a drastic decrease of the public share in production. Consequently, conflicts related to the operation of reservoirs have...
