Abstract
[Resument] A model for the propagation of water waves is presented, which retrieves the
concepts of rays and fronts from the geometrical optics approximation. Their definition here
is nevertheless different in that it considers both refraction and diffraction, solving thus most
of the problems usually associated with ray methods
