One of the most crucial aspects of dam construction is stability under a seismic load. The breakdown of the dam could cause a catastrophic effect on downstream areas. For that, the safety of the facilities lies in their stability. Dams must be stable and withstand the loads placed on them. They are national security facilities. Because dam collapse causes unbridled humanitarian, economic, and social disasters, its construction must be scrutinized and strive to reach the best design with the best materials. The researchers sought to conduct several studies to know the dam’s behaviour during earthquakes, the role of their geometric dimensions, and the technical condition of the soil on which the dam was founded or formed. The simulation and the results indicated that the soil liquefaction state should be reduced, and the three-dimensional results should be analyzed to predict the locations and forms of deformations and the ability to deal with them
