Finite difference model for tidal flows in the Arabian Gulf

A two-dimensional hydrodynamical model for tidal flows in the Arabian Gulf is developed. The model uses variable mesh-sizes to handle a more detailed tidal current filed in selected sub-regions. In this study, a three-block model scheme is developed in which the deep areas are covered by a relatively coarse grid and the shallow coastal areas by a finer grid. The third block, which is a super-fine mesh in the area of Dhahran, Bahrain and the West coast of Qatar, is included in the model to predict the more detailed tidal current field in this area. A finite difference model is utilized to solve the partial differential equations considered in the model.
