Abstract

Nowadays, sea operations require accurate prediction of the characteristics of the waves in the coastal and offshore areas. For modeling wave characteristics, there are various methods such as empirical methods, numerical methods and soft computing methods. In this research, the SWAN numerical model for modeling of wave characteristics in Hormuz Strait area was used. First , a global model for modeling the characteristics of the waves in the Persian Gulf domain was built. Then, the boundary condition obtained from the global model for local modeling with a larger resolution in the area of Hormuz Strait was used. The local model constructed in the Hormuz Strait area was calibrated using the recorded waveforms of the buoy deployed in that area and then was validated. Comparison of the results with the measured data of the Hormuz Strait buoy shows that the modeling has been carried out in this area has very precision results.
