This study evaluates the available eutrophication control techniques that could be applied in Keban Dam Reservoir. A limited reduction of phosphorous was shown to be achieved by pre-dam construction on the major nutrient source, Murat River. Biomanipulation was evaluated as an ineffective method. A performed analysis has shown that only a drainage basin management program may decrease the phosphorous loading to the extent desired.

This study investigates the performances of reduction methods of the seepage problem at the foundation of a real embankment dam, Oğulcuk Dam located in Yozgat, Turkey. The steady-state seepage modeling is used in the analysis. The variation of relief wells inner diameter, location and spacing parameters are compared with each other and are also compared with different alternatives, such as cutoff walls, core trenches, and cutoff walls with blankets. Different variations of those methods i.e. locations and d...
Kayraktepe dam and HEPP, environmentally acceptable alternative solution
Sever, Özgür; Tiğrek, Şahnaz; Department of Civil Engineering (2010)
In this study, alternative solution of Kayraktepe Dam is investigated. Kayraktepe Dam was planned more than 30 years ago, but due to various reasons the construction could not be realized. In this study, an alternative feasible formulation was developed. Former Kayraktepe Dam was planned for multiple objectives: flood control, energy generation and water supply for irrigation. The newly developed formulation was designed to meet these objects as well.
On the Optimum Layout of a Drainage Gallery in Concrete Gravity Dams on Isotropic Foundation
Daghestani, Tameem; Çalamak, Melih; Yanmaz, Ali Melih (2019-11-01)
This study investigates the optimum location of drainage galleries of concrete gravity dams under usual, unusual, and extreme loading conditions. The uplift and the stress distributions were computed using the gravity method and the beam theory, whereas the leakage rate into the gallery was determined by the finite-element method. The results show that the presence of a drainage gallery can reduce the uplift by over 60 percent compared to a non-drained case. The suitable gallery location shifts toward the u...
An Investigation of the Ground Motion Scaling Procedures for the Nonlinear Seismic Analyses of Concrete Gravity Dams
Soysal, BERAT FEYZA; Ay, Bekir Özer; Arıcı, Yalın (2019-07-03)
Seismic assessment of gravity dams is generally carried out using time history analyses. Scaling of the motions is commonly used; however, in contrast to buildings, the performance of scaling procedures at predicting the mean and reducing the dispersion in engineering demand parameters (EDPs) is not known. The main goal of this study is to assess the performance of different scaling procedures in predicting seismic demands on dams. The performance regarding the prediction of the damage and the required numb...
An evaluation study on instrumentation system of Cindere dam
Sezgin , Özgün İlke; Yanmaz, Ali Melih; Department of Civil Engineering (2008)
In this study, the first hardfill dam in Turkey, Cindere Dam, is evaluated regarding current and alternative measurement systems in detail. Cindere Dam is a notable project, especially with its height as an example of hardfill dam, not only in Turkey but also in the world. First, the current instrumentation system of Cindere Dam is evaluated as a whole with reference to the parameters measured, instruments and data acquisition system. Second, an alternative instrumentation system is developed by using addit...
