Designing a Numerical Model to Study the Effect of Tide and Wind in a Theoretical Basin in Similarity to Persian Gulf

The design of oceanic numerical model for Persian Gulf to predict oceanic phenomena and parameters is one of the most important ways of preventing or solving problems environment and designing of the oceanic model similar to it is an effective method that can explain physical response of environment to different situations. Purpose of this research is designing oceanic numerical model for environment similar to Persian Gulf, to predict its reaction in return effect of tide and wind. This three-dimensional model based on primitive equations in spherical coordinates system with sigma vertical coordinate. To solve equations of model is used finite difference method. Compared with similar models, model framework and calculate more logical tension between are the benefits of this model. An oceanic five-layer basin is considered with maximum and minimum depth 100m and 80.09m. The average daily wind in Persian Gulf, the average daily salinity and water temperature and the changes in the water level in Strait of Hormuz are used in this model. The two-year implementation of model showed that in this basin, the tidal force is a dominant force compared with windy force and density gradient, also the maximum current in strait is 1.98 m/s which can create anticlockwise circulation in basin. Maximum total change of water height is 2.98 m in relation to the static level. Implementation results of this model correspond to the oceanographic reality of Persian Gulf, while matches with purpose; it is the basis of suitable model for Persian Gulf.
