In this paper, the unstructured mesh is generated with numerical method based on the conception of Delaunay Triangulation, and the mesh is optimized with LOP (Local Optimization Procedure) method. The two dimensional tidal model is solved numerically with Finite Volume Method in unstructured triangulation mesh. Numerical experiments show that the numerical model is effective to compute the tidal current in the coastal area with complex boundaries.
