This test establishes a simple case of spectral waves obliquely approaching a plane beach and is described in detail in:

The case consists of spectral waves approaching a mild sloping (1/80) plane beach with an oblique angle of incidence. The wave forcing is simulated with SWAN by specifying a JONSWAP spectrum for 2 m offshore wave height with a peak period of 10 s at an angle of 10 degrees for the incoming wave field. SWAN was configured to use 90 directional bins and 30 frequency bins between 0.04 and 0.5 Hz. Additional parameters for each circulation model used for the plane beach test case are listed in Table1. Each circulation model computes the radiation stress forcing based on the SWAN wave output using the formulations described above for each model. There is not a feedback of the currents to the wave model for this application. Also we neglect the contribution from the roller model. Both circulation models impose the same quadratic bottom stress formulation using the depth average currents.
