Abstract
Tidal field data is very important in coastal engineering researches such as developing the beaches, calibration of Numerical hydrodynamic models, hydrography, sediment transport and other things.The aim of this study is to evaluate and validate numerical hydrodynamic modeling by using field measurements of tidal measuring stations and to find a level tidal model in the Persian Gul. Therefore, bathymetry and coastline data and one year data of ten tidal measuring stations in the Persian Gulf and the wind field GFS were used for this purpose.Tidal currents were simulated using FM[1] software MIKE21 with irregular mesh structure and considering the astronomical forces, and verified by the results of the station measurements. In the next step, the tidal components were extracted. The simulation of the Persian Gulf's tidal current with the MIKE model was very well adapted to the field data of the tide measuring stations.In the final stage, the values provided by the FES global model were extracted using Matlab software. The results of the tidal analysis derived from the global oceanic tide model were evaluated and compared with the results of the tidal analysis derived from the modeling (results from the tide measuring stations). Based on the results in the study area, the tidal components obtained from the global oceanic tide model in the coastal and shallow zones, showed a low correspondence and accuracy with the tidal components of the tide measuring stations. This is despite the fact that less difference was observed between the corresponding components in deep areas.
