79. In addition, Uliczka and Dette conducted several prototype-scale flume tests using irregular waves 

 and approximately three times more sand in the profile to avoid exposing the concrete revetment. One of 

 the cases used the same grain size and initial slope as the regular wave case shown in Figure 6. The only 

 difference was the sand berm width, which was three times as wide for the irregular wave test. This case 

 was selected for reproduction during the irregular wave verification of the scale model relationships. In the 

 prototype case, a JONSWAP spectral representation was used to simulate the irregular waves. Significant 

 wave height, peak spectral period, and water depth were specified to be equal to the same wave values as 

 used for the regular wave prototype condition.
