| Zusammenfassung |
| Propagation of water waves in coastal zones is mainly affected by the influence of
currents and bathymetry variations. A linear, elliptic equation allowing to describe the
propagation of water waves in arbitrary, slowly varying, currents and bathymetry,
was initially derived by Kirby (1984). His approach was based on the linearization
of the depth integrated lagrangian, assuming the current profile not to depend on
depth.
In this work, we derive a linear equation, extending Kirby’s approach to currents varying
linearly with depth. A numerical study is developped, aiming to demonstrate the influence of
the vorticity on propagation. Both one and two dimensional cases of propagation are
considered, and discussed.
