In most applications the profile of interest is relatively well defined. Hence, the
selection of the profile to be modelled reduces to deciding on the position and
type of the offshore boundary. Usually you would apply an internal wave gen-
eration boundary. A typical situation is schematised in Figure 5.6.

The line on top of the 2D bathymetry plot indicates the location of the
extracted profile. It is noticed that the bathymetric profile includes depths
larger than zero, which means wave breaking and wave run-up have to be
included in this model setup. More information about this example can be
found in section 4.3.3 Torsminde barred beach.
As in 2D applications the minimum water depth in the model area defines the
grid spacing, as the minimum wave length is defined by the minimum water
