Última Une formulation parabolique pour la propagation en profondeur finie des ondes de gravité en surface ArchiMer Mordane, Soumia; Maroihi, Kamal L; Orbi, Abdellatif; Chagdali, Mohamed. This paper deals with the parabolic formulation of propagation equations of gravity waves in surface in terms of angular capability with respect to the privileged propagation direction. This parabolic formulation is obtained by splitting the Berkhoff equation operator into two parabolic operators representing progressive and regressive wave propagation. The use of Pade approximants permits to derive simultaneously parabolic equations for the transmitted waves and the reflected waves. Two well-known reference examples, which represent the propagation of the wave when a caustic occur, are studied numerically and the results are compared with those of the literature.
