2DH Boussinesq Wave Module - Examples

= 2.65 m with a spectral peak period is T
p
= 8.6 s. The waves are synthesised
based on a mean JONSWAP spectrum, as the minimum wave period is set to
T
min
= 5.7s. The wave disturbance problem can be solved using the classical
Boussinesq equations (i.e. B= 0). Please note that the truncated wave spec-
trum is not rescaled, i.e. the incoming wave height is less than 2.65 m.
A grid spacing of 5 m is chosen and a time step of 0.4 s. This results in a
maximum Courant number of 1 in the deepest part of the model. The length
of the simulation is 12 minutes (corresponding to 1801 time steps).
Model results
The model results are presented in Figure 4.7 showing a contour plot of the
instantaneous surface elevation and a map showing the isolines of the simu-
lated wave disturbance coefficients (after 12 minutes).
Figure 4.8 shows a 3D plot of the instantaneous surface elevation for entire
harbour.
The wave disturbance coefficient along the main quay wall of the cruise ter-
minal is 0.05-0.20 for this event. Other statistics (max., min., mean, std. dev.
and number of data) for the two areas defined in the area code map file can
be found in the ASCII file named WaveDisturbanceAlongNewQuay.txt.
