The propagation term was implemented by a semi-implicit numerical scheme, the so-called [theta]-method, for numerical stability. UFDVM exploited finite volume numerical scheme in horizontal diffusion term. Because the model used orthogonal unstructured computational grid, much flexibility to resolve complex coastal boundaries was allowed without any transformation of governing equations. The model has ability to treat wetting and drying of land. UFDVM was implemented Z-grid in vertical direction. The equilibrium turbulence model is used to determine the vertical eddy viscosity.
