Modelling of seepage from foundation and body of earth dams by finite element method

In this study, seepage investigation through earthen dam, its velocity and distribution of pore water pressure on the Mashkyd dam in Sistan and Baluchestan province has been studied. In order to modeling and analyzing of the results from the movement of water in porous media, the Abaqus software is used which is based on the powerful numerical method finite element method. According to the results, the maximum velocity is 2.47×10-5 (meter per second) which is estimated in drain. Then for leakage detection, three sections of mashkyd dam were considered. The results show that seepage through the core that encompasses all the leakage flow is 7.07×10-6 (cubic meter per second). In the next step, the influence of specific weight of fluid on the leakage and pore pressure in the mashkyd dam was evaluated. According to the results, by increasing the specific weight of water, leakage decreases and pore water pressure increases.
