Abstract: In this article, seepage phenomena through the karstic limestone foundation of Behesht Abad dam are investigated. In order to get a state of seepage and determine the depth of grouting curtain, it has been tried to evaluate the seepage of Behesht-Abad dam foundation and its abutments by the help of numerical analysis and UDEC 4.0 software. To perform this research, firstly, geological data during a study phase in Behesht Abad dam site was gathered, and then different methods have been used to calculate the engineering properties of rock mass. Therefore the structural model of dam foundation based on the geological data constructed and various boundary conditions including different heads were applied on the model and the suitable depth for the grouting curtain was proposed.
