Petten is located on the Nw coast of the Netherlands, where the coastline
is almost straight.
This justifies the use of a 1-dim computation along a transect
normal to the coast.
The results are Compared with a 2-d computation
which was done within the framework of the RIKZ test bed
(run F91PET02, see WL | Delft Hydraulics (2000)),
and with measurements.
Various physical formulations are applied and Compared,
see the following list of cases:
14 cases are considered:
- physics formulation from the file 'Physics.swn',
usually the standard Swan formulation
- 1st generation with triads active
- 2nd generation with triads active
- 3d generation (WAM-3) with triads active
- 3d generation (WAM-4) with triads active
- 3d generation (WAM-3) without triads
- 3d generation with Westhuijsen formulation
- breaking with variable Gamma (Battjes&Stive,19??)
- breaking with constant Gamma (BalDock,19??)
- breaking with variable Gamma and full Rayleigh distribution
- Jonswap friction (default constant)
- Jonswap friction dependent on directional spread
- Friction according to Collins
- Friction according to Madsen (roughness 0.05 m)
It is seen that Hs in runs h and j are significantly above those from
the other runs.
Comparisons of most of the computations with observations are found in plot
Spectra computed in case F03a at 3 locations are Compared
with measurements in plot F03spec.plt.

Suite of benchmark tests for the shallow water wave model Swan Cycle 2
The data for this test were adapted from the Suite of bench mark tests for the
shallow water wave model Swan.
