Ilısu Dam and HEPP, investigation of alternative solutions

Yalçın, Emrah
This study is an assessment of a hydraulic solution not only rescues Hasankeyf with countless ancient monuments from inundation but also supplies the foreseen energy production of the Ilisu Dam and HEPP Project. An alternative composed of five dams on the Tigris River and its branches was developed as a result of the conducted hydro-meteorological, water potential, flood analysis and optimization studies considering the topographical and geological characteristics of the proposed dam locations. While there is a 27 percent decrease in the overall reservoir area compared to the existing project, 4426.1 hm3 of water can be stored in these dams with a fill volume of 14.8 hm3. Over this storage, determined according to the maximum water levels designated by considering the upstream schemes developed by General Directorate of State Hydraulic Works (DSI), General Directorate of Electrical Power Resources Survey and Development Administration (EIE) and incorporated companies according to Law No.4628, a volume of 3634.4 hm3 can be used as active storage. In the fully developed upstream stage, according to the conducted consecutive operation studies, while the existing project has an energy production capacity of 3094.3 GWh/year, the proposed project is capable of providing 3139.1 GWh/year with a smaller installed power although there is a slight decrease in the produced firm energy.


Ground motion scaling for the prediction of the seismic response of concrete gravity dams
Duygu, Mustafa Berk; Arıcı, Yalın; Department of Civil Engineering (2014)
Designing dams for seismic safety gains importance as the number of dams are increasing as a result of increasing need in water storage and hydropower. To define a structure’s seismic safety, scaling of accelerograms should be considered as one of the most crucial elements. Appropriate scaling of ground motion records is required to better estimate the linear and nonlinear structural response of a structure. Although, in literature, there exist numerous methods dealing with this issue, it is required to det...
Low-cost seismic base isolation using scrap tire pads (stp)
Özden, Bayezid; Türer, Ahmet; Department of Civil Engineering (2006)
This thesis focuses on the experimental studies conducted on the development of low-cost seismic base isolation pads using scrap automobile tires. Seismic base isolation is a well-defined building protection system against earthquakes, on which numerous studies have been conducted. The majority of the previous studies focus on the performance improvement of the base isolation systems. However, this study aims at cost and weight reduction of seismic base isolation pads by recycling otherwise useless material...
Investigation of the effect of soil structure interaction on the behavior of concrete faced rockfill dams and assessment of current analysis methodologies
Erdoğan, Emrah Erşan; Arıcı, Yalın; Department of Civil Engineering (2012)
CFRD (Concrete Faced Rockfill Dam) construction becomes more frequent recently not only because of its secure nature, but also its economical cost where its built up material is feasible to obtain. Although CFRDs are known to be safe compared to other dam types, it is behavior during an earthquake loading still not a well-known aspect since it is mostly constructed in regions of low seismicity until now. Considering this fact, this study‟s primary purposes are set to find the mathematical model size of a “l...
Seismic testing of a scaled roller-compacted-concrete gravity dam
Gharibdoust, Ali; Binici, Barış; Department of Civil Engineering (2016)
Within the last half-century, seismic response analysis of concrete gravity dams has been extensively studied. Studies reveal that two types of failure modes prevail in the form of dam body cracking or base slide. The literature lacks the conditions that clearly differentiate the two failure types. In this context a state of the art single degree of freedom pseudo-dynamic testing was developed to assess the gravity dam response on smooth foundation interface. Three different hazard levels of earthquake name...
Development of a decision support system for optimal instrumentation of concrete faced rockfill dams
Arı, Onur; Yanmaz, Ali Melih; Department of Civil Engineering (2016)
In this study, an algorithm for optimal design of instrumentation systems for concrete faced rockfill dams was developed. The aim of this algorithm is to determine the number and the location of individual instruments for stress monitoring. It was intended to develop a user-friendly and flexible algorithm that would be applicable in reliable and economic design of instrumentation systems for concrete faced rockfill dams. The first developmental step was the generation of a model cross-section for a concrete...
