Long-term numerical modeling of wind flow and circulation in the Persian Gulf

A three-dimensional hydrodynamic model was implemented to study water circulation in the Persian Gulf using the FVCOM model. This model included accurate depth measurements of the Persian Gulf, long-term wind regime, evaporation, precipitation, surface temperature and also water inflow from Arvand River. Boundary data included changes in water tidal level as well as changes in temperature and salinity of water entering the model. Modeling was performed over a long period of 16 years. The results of the model were compared with field data on water level and flow velocities using the statistical parameters of root mean square estimation errors (RMSE) and correlation coefficient. Changes in water level and horizontal water velocity components had a high correlation with field data and showed a very low error rate. Also, the pattern of wind currents at the surface and depth in the Persian Gulf were completely consistent with the results of previous valid studies. The results of the model show the ability of the model to use it in marine research.
