Benchmark comparisons between an NRL, SCC high-frequency shallow water normal mode code and commonly used codes with more detailed explanations of the method

Abstract

In the past, a new normal mode code developed at NRL, Stennis Space Center based on a new expansion method was discussed. The expansion functions are solutions of a related iso-velocity profile. The method is discussed in more detail and compared with old perturbation methods, the Galerkin method, and variational methods. Then benchmark comparisons with other codes are presented.
