The correct generation of the incident wave conditions can only be obtained
on the assumption that the water depth is constant along the open boundary
or the internal generation line. Therefore, the open boundaries and internal
generation lines should be placed in areas where there is a small variation in
the water depth.
The example Rønne Harbour uses one generation line.
Two generation lines
To model oblique waves, relative to the model grid a very wide generation line
would be required if using only one generation line. Therefore two generation
lines is preferred in many cases.
An example is shown in Figure 5.14, where it can also be seen that the area
with artificial land on the right-hand side of the harbour entrance has been
enlarged compared to the example above. In Figure 5.18 is shown how to
join internal generation lines in a corner.

The example Hanstholm Harbour uses two generation lines.
Position of generation line
Definition
The (internal) generation line should be parallel to either the x-axis or y-axis
of your bathymetry. As illustrated in Figure 5.16, the waves are always sent
off from the left hand side of the line as seen from the starting point, see also
Figure 5.17. You should be careful only to send off waves to one side of the
generation line, or in other words
