Diffraction test
Purpose of the example
This example is included to illustrate the phenomenon of diffraction. Diffrac-
tion is an important process in regions, which are sheltered by barriers such
as breakwaters, jetties or inlets.
The example describes what happens when a single fully reflecting breakwa-
ter interrupts a regular wave train.
Model setup
The model setup is illustrated in Figure 4.3. The model size is 1200 m by 700
m with a uniform depth of 40 m. Wave absorbing sponge layers are applied at
the eastern and northern model boundary, while the western boundary is
treated as fully reflective. The area of interest is the shadow zone behind the
breakwater. Due to radiation of energy from the point of diffraction the west-
ern boundary has to be placed quite far from this area to avoid reflections.
