Earthen dams, as one of the largest earthen structures, are exposed to various failure mechanisms, some mechanisms such as cracking and hydraulic failure are created in the body of the dam, and some other mechanisms such as liquefaction, divergence and dissolution are caused by the characteristics of Geotechnical is the foundation of the region. In this research, studies were conducted to evaluate geomechanical parameters effective in the occurrence of hydraulic failure and to understand the interaction of the dam body with these parameters and to provide a safe model to reduce the risk of building earthen dams and to study how to deal with problematic foundations. Modeling of the problem was done with finite element numerical method using PLAXIS computing code. In this laboratory, by changing the mixing percentage of the dam wall materials, their effect on the behavior of the earthen dam was studied. The results showed that the laboratory results presented in this research have a good overlap with the results of the software and by using this device, it is possible to calculate the amount of seepage in each mixing design according to the dimensional analysis.
