16. Command signals were generated to simulate the Texel Marsen Arsloe 

 shallow-water spectrum (Hughes 1984) for the four design wave periods. The 

 range of design wave heights was obtained by varying the percentage of the 

 command signal sent to the wave generator. The duration for each test condi- 

 tion was 30 min model time (~3 hr prototype) . 



17. The sequence of producing the wave conditions was from shortest to 

 longest wave period beginning with the lowest wave height. Damage was 

 determined after all wave conditions at each set of constant wave height (13-, 

 16-, 20-, 24-ft) were generated. 



18. Prior to installation of the breakwater section, the wave facility 

 was calibrated for the selected wave conditions. Arrays 1 and 2 were located 

 as shown in Figure 3, and Array 3 was positioned so the middle gage was 

 directly above the top of the 1:50 slope. Incident wave measurements from 

 Array 3 gave wave heights at the toe of the breakwater that were not affected 

 by reflections from the breakwater.
