Dams are very critical structures that are used mainly for energy production, agricultural irrigation, water storage. Seepage problems are seen in dams may require long-term and costly remediation programs by reducing the benefits of projects built for purposes such as drinking, irrigation, and energy. A widespread and potentially dangerous phenomenon related to flooding is seepage under dams, and the formation of sand boils. In this study, Koyunbaba dam located within the boundaries of Ankara/Kalecik county is examined. The study aims to calculate the amount of leakage of the alluvium lateral on the dam foundation and to calculate the optimum location, thickness, depth, and permeability of the slurry trench that can be built under the dam foundation. Groundwater Modeling System SEEP2D software which uses finite element method for calculations is used. The seepage results showed that the slurry trench significantly reduces the seepage. The thickness, depth, and permeability of the slurry trench have also been found to be essential factors in reducing leakage. It has been found that the slurry trench minimizes the leakage by up to 99%. Also, the factor of safety against piping which may occur in the downstream toe of the dam is examined. The coefficient of safety results showed that the base slurry trench should be extended to an impermeable layer or keyed the impermeable layer.
