In this study, the mechanical behavior of Shirin-Dare Dam was evaluated at the end of construction, initial impounding, and operation time through using the results of instruments and numerical analysis conducted by FLAC software. The results showed that the settlements calculated from the numerical analysis were in reasonable agreement with the data recorded by the instruments in the field. This confirms the validity of the material properties selected based on field instrumentation. The numerical results pertaining to the calculations of the pore water pressure distributions, embankments stresses, and the settlement behaviour of the dam showed acceptable performance of the studied dam. The sensitivity analysis of hydraulic fracturing of the dam using the arch ratio resulted in comparable performance of similar geostructures across the world.
