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 depths are also discussed and compared with each other and relief wells. Performances of relief wells are also compared in terms of cost. In general, it is presented that between the compared reduction methods of seepage, relief wells has a better performance and can be used as a remedial measure to protect the alluvial foundation and toe of embankment dams from the hazardous effects of foundation seepage.
