Introduction of the seepage device for examining the one to four hundred model of the Karkheh Dam.

Earth dams, as one of the largest earthen structures, are subjected to various failure mechanisms, some of which, such as cracking and hydraulic failure, occur within the dam body, while other mechanisms like liquefaction, divergence, and dissolution arise from the geotechnical properties of the foundation or the region's bed. In this research, which is derived from a doctoral dissertation, an evaluation of the geomechanical parameters affecting the occurrence of hydraulic failure was conducted to understand the interaction between the dam body and these parameters and to provide a safe model for reducing the risk of constructing earth dams and studying ways to address problematic foundations. The modeling of the issue was performed using the finite element numerical method with the PLAXIS computational code. In this laboratory study, by varying the mixing percentage of the materials in the cutoff wall, their effects on the behavior of the earth dam were investigated. The results indicated that the laboratory results presented in this research have a suitable overlap with the software results, and using this device, the seepage in each mixing design can be calculated based on dimensional analysis.Earth dams, as one of the largest earthen structures, are subjected to various failure mechanisms, some of which, such as cracking and hydraulic failure, occur within the dam body, while other mechanisms like liquefaction, divergence, and dissolution arise from the geotechnical properties of the foundation or the region's bed.
