Abstract:
We review exact solutions for gravity waves in deep water. All of
them are obtained within the Lagrangian framework and are
generalizations of Gerstner waves (to the cases of inhomogeneous pressure on the free surface and taking the rotation
of the fluid into account). The Cauchy invariants are found for each type of waves.
Keywords:
Lagrangian coordinates, Cauchy invariants, Gerstner wave.
