Abstract: In the present study a numerical method is developed for solution of shallow water equations in complex geometries. A Multi-Block method is employed in conjunction with non-orthogonal curvilinear coordinate system, which gives the numerical method the flexibility to tackle flow domains with any complex boundary. The model is based on collocated grid arrangement and the control volume method is used for solution of equations. A SIMPLEC-like algorithm is employed to find the water surface elevation. The model is applied for simulating laminar re-circulating flow in a circular basin and results are compared with other numerical models.
