| Summary: | We consider Euler equations with stratified background state that
is valid for internal water waves. The solution of the
initial-boundary problem for Boussinesq approximation in the
waveguide mode is presented in terms of the stream function. The
orthogonal eigenfunctions describe a vertical shape of the
internal wave modes and satisfy a Sturm-Liouville problem. The
horizontal profile is defined by a coupled KdV system which is
numerically solved via a finite-difference scheme for which we
prove the convergence and stability. Together with the solution
of the Sturm-Liouville problem, the stream functions give the
internal waves profile. |
