Abstract

A set of model equations for water wave propagation is derived by piecewise integration of the primitive equations of motion through N arbitrary layers. With N separate velocity profiles, matched at the interfaces of the layers, the resulting set of "extended" equations have 2N-1 free parameters. The values of these parameters is chosen based on an optimization with known analytical properties of water waves. The optimized model equations show good linear wave characteristics into deep water, with accuracy increasing with number of layers. A numerical algorithm for solving the model equations is developed and tested against one- and two-horizontal dimension cases. Agreement with laboratory data is excellent.
