Estimation of during construction settlement of embankment dams is highly important in design and safety control of embankment and appurtenant structures. In order to evaluate the ability of Mohr-Coulomb and Soft Soil Creep models in prediction of embankment settlement, Alavian dam was selected as a well constructed and monitored case. The features of mentioned models and the dam under study have been explained in brief. The parameters required for analyses were provided screening laboratory and field test results. Then the during construction settlement profiles were established using Mohr-Coulomb and Soft Soil Creep models and compared with those obtained by direct field measurements with settlement meters. It was disclosed that, in general, the predicted settlement profiles are in agreement with that of field measurements. With Mohr-Coulomb model, better agreement is observed only in short term than the long term. However, as time passes the field measured profiles precede the predicted values. With soft soil creep model, however, agreement between the predicted and field measured values is quite encouraging all through the construction period. The predicted maximum settlement using both models, occur at 1/3 of embankment height which is coincident with field measurements.
