F03. Petten

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:

F03a
physics formulation from the file 'Physics.swn', usually the standard Swan formulation
F03b
1st generation with triads active
F03c
2nd generation with triads active
F03d
3d generation (WAM-3) with triads active
F03e
3d generation (WAM-4) with triads active
F03f
3d generation (WAM-3) without triads
F03g
3d generation with Westhuijsen formulation
F03h
breaking with variable Gamma (Battjes&Stive,19??)
F03i
breaking with constant Gamma (BalDock,19??)
F03j
breaking with variable Gamma and full Rayleigh distribution
F03g
Jonswap friction (default constant)
F03h
Jonswap friction dependent on directional spread
F03i
Friction according to Collins
F03j
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 F03.plt.
Spectra computed in case F03a at 3 locations are Compared with measurements in plot F03spec.plt.
