| Abstract: | A numerical model is presented for computing the deformation of highly dispersive waves on a current on the basis of the enhanced Boussinesq-type equation set proposed by Chen et al (1998). Basic properties of the linearized equation set are shown. The present model includes a new technique to handle various fundamental boundary conditions, such as incident, reflective, radiating and transmittal boundaries, in a consistent manner by applying the Levenberg-Marquardt least-squares algorithm. Computational examples are shown for partial reflection with or without a current and for reflection-transmission both for regular and random waves in one-dimensional field and the breaking wave deformation on a current. Two-dimensional wave field around a rip current is also computed. | |
