چکیده

The prediction of wave parameters based on measured wind parameters plays a crucial role in Coastal and Ocean Engineering. This is particularly important in designing coastal and offshore structures, as there may be limited availability of wave measurement stations. In such cases, wave prediction methods can be used as an alternative to estimate wave characteristics during the design phase of various inshore and offshore structures.This research compares the prediction of wave characteristics between different semi-empirical methods and the MIKE21-SW model. For this aim, the measurements of the wave recorder buoy of the Caspian Oil Company used for wind data as well as wave characteristics. Statistical indices indicate that the SPM method is the most applicable method than other Semi-empirical methods for predicting the wave characteristics. The error of the semi-empirical method is about twice than the numerical method. There is more correlation between the obtained and measured data in the numerical method compared to the semi-empirical methods.
