A 60 YEARS WAVE HINDCAST STUDY IN THE SOUTH OF PERSIAN GULF USING SWAN MODEL & SEMI-TIME DOMAIN METHOD

The goal of this study was to simulate the wave characteristics in the south of Persian Gulf over a 60 year period. Wind data from the study area including offshore measurement, satellite observation and numerical atmospheric models were collated and analyzed. The modified NCEP/NCAR wind field was chosen as input to the SWAN model which has the longest duration among wind data sources. SWAN model was run in stationary mode for different cases of wind speed and direction and lookup tables were made for each wave parameters in each point of interest. A 60 year time series of wave characteristics were made using these lookup tables. Having such long time series enables us to calculate the wave characteristics with larger return periods. Execution time was drastically decreased using this method.
