In recent years, a number of different approaches have been developed to solve the geotechnical problems including static and dynamic analysis of earth dams. Emarat dam is an earthen dam with a clay core on the Darehrood River, one of the branches Aras river constructed at a distance of 100 km from the Meshkinshar city. In this study, using FLAC2D software and the finite difference method, the strength characteristics of the body and foundation materials of this earth dam have been identified and the static and dynamic behaviour of Emarat dam during the construction and inundation has been investigated. Regarding to achieved analysis it can be declared that Emarat earth dam has been statically stable during the critical process of ending of construction, dewatering stage and after dewatering stage. Considering to input earthquake which its frequency is close to Emarat earth dam frequency, it is dynamically stable. Emarat Dam Static Analysis Dynamic Analysis Numerical Methods FLAC2D
