During each iteration of WAVES, the movement of a set of waves from deep water to the shoreline is simulated. From the tables produced by these programs the stability of surface sediments can be assessed, the wave conditions capable of moving sediment in the onshore-offshore direction can be identified, and the effects of wave action on offshore coastal structures and oceanographic instrumentation can be determined.
