Abstract: Two cases of scaling waves at tidal inlets with physical models are examined. One case was for a study of wave breaking over an ebb shoal in the presence of ebb currents (1:50 scale). Wave heights were compared for two different model scales. The other case compared physical model and prototype currents adjacent to a jetty resulting from a combination of tidal and wave-generated currents using a 1:75 scale model. Results indicated tidal inlet models at these scales reproduce the nearshore wave heights and currents well.
