Khowr-e Musa at the northwestern terminus of the Persian Gulf sedimentary basin is the widest and longest inshore marine outcrop in the entire coast of the iran at present. In this research, the tidal Current velocity and tidal water level in the Khowr-e Musa estuary was modeled in a 15-day period from 18th of November 2006 by using the Telemac two-dimensional hydrodynamic software. For this purpose, the irregular mesh in two dimensions was selected from the smallest mesh of 70 meters to the largest mesh of 210 meters. The topography of the area was added to the grid of mesh by using an interpolation method. Then TPXO database tidal data applied along the boundary of model. The friction coefficient was calculated using the Stickler theory with the value of 40 m1/2s-1 and the model was executed with a time step of 10 seconds. After Sensitivity analysis and calibration, the model was validated by using measurement data that’s provided by the ports and maritime organization. The results showed a good correlation of 94% between the results of the water surface level of modeling the tidal and measurement data and correlation of 73% between the results of the current velocity of modeling the tidal and measurement data, so the TELEMAC two-dimensional hydrodynamic model is suitable for studying the tidal current.
