Abstract: In this paper, simulation of tidal currents in the Persian Gulf is performed by the solution of the hydrodynamics equations. The hydrodynamic equations utilized in this work consist of depth average equations of continuity and motion in two dimensional horizontal planes (SWE). The effects evaporation is considered in the continuity equation and the effects of bed slope and friction, as well as the Coriolis effects are considered in two equations of motion. The overlapping cell vertex finite volume method is applied for solving the governing equations on triangular unstructured meshes. Using unstructured meshes provides great flexibility for modeling the flow in arbitrary and complex geometries, such as Persian Gulf flow domain. The results of the hydrodynamic model for fluctuating flow on the variable bed slope are compared with available analytical solution. The accuracy of the developed flow solver to simulate circulating flow patterns is assessed by comparison between numerical results and reported data in the literature for deep flow in a canal with sudden expansion. The performance of the computer model to simulate tidal flow in Persian Gulf domain is examined by imposing tidal fluctuations to the main flow boundary during a limited period of time.
