TEL2TOM: coupling TELEMAC2D and TOMAWAC on arbitrary meshes

In this paper, a novel approach is presented to perform coupled simulations of TELEMAC2D and TOMAWAC. In this approach different meshes are considered: a dense mesh for TELEMAC2D in order to manage fast and accurate resolution of the flow and a much coarser for TOMAWAC in order to increase the computational speed of the wave model. The communication of flow variables is implemented by means of linear interpolation. Two applications are presented utilizing the TEL2TOM functionality: the existing littoral test case from the TELEMAC2D test bank, and a real world application in the Belgian coastal zone.
