| Shallow water equations were applied to the flow in and through the opening to a coastal bay with different open boundary conditions. The open boundaries, shaped like a semi-circle, have various radii. the open boundaries therefore are defined in terms of radius given by multiple of the opening width, 2B. It was found from numerical experiments that for adequate results proper radius of the boundary is 3B or greater and that for radius greater than 3B the solutions become stable. For the solution of the shallow water equations a typical Galerkin's finite element method was used. |
