Abstract
For an island (called Mubarraz Shoal) located in the southern part of the Arabian/Persian Gulf, we performed numerical simulation, considering tidal and drift currents to study about the current and flow routes of coral eggs and larva around the island. On the basis of results, it was identified that eggs and larva were transported to the southeastward as northwest wind was significant all the time around the island in the sea area. However, the transportation interval is varied according to the strength of the wind. Accordingly, it was estimated that coral eggs and larva may stay near the island at the time of the transportation in case of light wind. Moreover, consequently, we made a comparison between 2D and 3D simulation results about the transportation interval. We found that the difference has increased when the wind is strong. Farther, the effect on one directional wind was examined by 2DV. Throughout, it was identified that there is a necessity for increasing number of vertical layers. It is because, when wind is stronger, the difference of current speed between the surface of 3D and 2D simulation has increased.
