Cross-slope wedge propagation is considered for the three-dimensional benchmarking of three underwater acoustic models, one based on normal mode theory and the other two based on ray tracing. To this end the benchmarking relies on analytic solutions for adiabatic and non-adiabatic propagation, as well as on experimental data from a scale tank experiment (a previous benchmarking with a parabolic equation model is known to provide extremely accurate predictions in all cases). The benchmarking allows to identify the advantages, accuracy and limitations of the considered models.
