Numerical modeling of wave and current patterns of a slope breakwater in the development plan

This paper deals with numerical modelling of wave and current patterns in the coastal city of Genaveh port (Bushehr province, Persian Gulf) with a sloping breakwater. Three breakwater arm patterns were defined based on the studied area's marine currents. Meteorological model wind statistics (ECMWF) and wave statistics (ISWM) and data from monitoring and simulation projects of the northern coasts of the Persian Gulf were used to model the hydrodynamics of the study area after the breakwater construction. In this numerical modelling, mike 21-SW and HD modules were employed to simulate the wave patterns near the three proposed breakwater arms. Based on observations of the hydrodynamic condition and with consideration of the design wave exhibiting a 100-year return period, it is indicated that an optimal pattern would yield significant wave heights and wave speeds of 0.2 m and 0.25 m/s, respectively, within both the existing and newly constructed harbour basins.
