Abstract
In recent years, the study of tidal currents has gained special importance due to economic, political, and environmental considerations, as well as its implications for maritime transport, navigational safety, and offshore structures. The Khuran Strait, located near the Strait of Hormuz in the Persian Gulf, is one of the most significant maritime areas. Thus, understanding tides, tidal currents, and their predictions is crucial in this region. We utilized the FVCOM model to simulate the speed and direction of tidal currents in the channel. The model's main inputs include the roughness coefficient, salinity, temperature, density, bathymetric data, and tidal information. Additionally, tidal time series were applied to the model using eight harmonic components. To evaluate the hydrodynamic model, we compared simulated current speeds and directions, as well as water levels, with observed data from specific locations. The results indicated a correlation of 75% for speed values and 89% for current direction. The RMSE values were 0.09 m/s for speed and 0.35 degrees for current direction. We used parameters such as RMSE and RV for statistical evaluation. Using the results of the FVCOM model, a Tidal Current Diamond prediction was presented.
