The depth average module of NASIR finite volume solver was applied to study the tide induced currents in Khowr-e-Musa estuary. The model computes water level variation and velocity components in horizontal plane solving depth average continuity and momentum equations considering the hydrostatic pressure distribution. The software takes into account the bed and wall geometric complexities and resistances. In the present work, the option of cell vertex finite volume method of the software was applied for discretizing the governing equations. The descritized equations were solved on a triangular unstructured mesh. The solution domain was descretized using Delauni triangulation method. For damping out numerical oscillations of explicit solution procedure, an artificial viscosity formulation suitable for the triangular unstructured meshes was applied. After verification of the accuracy of the software with analytical solution of tidal currents in a dead end channel, the efficiency of the results was assessd by simulating flow on Khowr-e-Musa multi-branch estuary.
