Title :CATWAVES Prediction of Linear and Nonlinear Wave Motion in Unbounded Coastal Domains

Abstract :The CATWAVES is a package of Fortran programs, based on the finite element method, for linear and nonlinear wave analyses in unbounded coastal domains. This package consists of three procedures: (I) the finite element mesh generation routines for preprocessing, (II) the finite element analysis routines of wave motion and (III) the graphics routines for post-processing. The model equation of wave motion implemented in CATWAVES is a variant of the mild-slope equation and combines the linear dispersion with weak nonlinearity. The boundary conditions applicable to the model are wave reflection along the shorelines and the boundary of coastal structures, discontinuous changes in water depth, such as occur in reef coasts, and the radiation condition at infinity. Initially, the CATWAVES imposes, on the user, preparation of two data files for the mesh generation routine, i.e., bathymetric and finite element mesh data. After preparation of these data, the system successively creates the input/output data files and leads to the final results together with high-quality graphics.
