N2 - The purpose of this contribution is to present two approaches to analyze a 2D halfspace with two empty canyons, exposed to an oblique incident S-wave. Two residuals are formulated to couple the free field solution for an incident wave front with the scattered wave field, which is described by the Wave Based Method (WBM). One residual is formulated as a Neumann boundary condition to fulfill the requirement of an unloaded surface. The second residual consists of coupling conditions to connect two substructures, of which one describes a scattered wave field and the other is composed of a free field and scattered wave field solution. Different numerical examples from literature are presented, and show that both coupling approaches deliver adequate results. Moreover, the numerical example of a halfspace with two canyons is analyzed to test the performance of the here presented formulations for the WBM.
