I am actually modelling a embankment dam both in SEEP/W and SIGMA/W. I have coupled SEEP/W with SIGMA/W and have used the mohr columb model for the analysis. After running my simulation, it is observed that the phreatic line obtained in SEEP/W and SIGMA/W are different and I dont understand why. Can Anyone suggest where I might be going wrong.

It is likely that the difference in the phreatic line is due to the different assumptions made in the Mohr-Coulomb model between SEEP/W and SIGMA/W. It is possible that the different assumptions have caused a difference in the results and it is worth checking the assumptions for each model to identify any discrepancies.
