Abstract
Usually gravity waves are described in terms of the velocity potential under the assumption of no vorticity. This hypothesis is difficult to justify and not useful if the induced boundarylayer must be studied. In the case of long crested waves a streamfunction representation can also be introduced. A variational principle is presented for periodic, finite amplitude gravity waves in terms of a stream function.
