The simulation can be combined with normal waves to simulated shoreline wave behavior. The shoreline simulation is a function of displacement (ie Animated Waves simulation).
To enable, set to Shoreline. Properties to control this simulation is found under the heading.
This is a realtime effect and cannot be baked. The simulation can follow the camera by setting to Viewer.
Example
See the Beach sample for an example of simulating a Swash Zone.
Warning
Results will greatly depend on the profile of the terrain and the waves.
