Figure 6. Harbor -side damage, Plan 1 



to the proposed rehabilitation section (harbor side) was less than 2 percent 

 and was considered "not damaged" for (H mo ) i < 17 ft . 



25. Transmitted wave heights (H mo ) t resulted from waves overtopping 

 the structure and wave transmission through the structure. Transmission data 

 for Plan 1 are listed in Table 2. Transmission coefficients 



Kt = (HmohAHmoh ranged from 0.17 to 0.32. Transmitted wave height plotted 

 as a function of incident wave height for Plan 1 is shown in Figure 7. (A 

 nondimensional plot of wave transmission is located in Appendix A, Figure Al.) 

 Wave heights on the harbor side approached 8 ft for the highest incident 

 waves . 

 Summary 



26. The tests indicated that the proposed section was stable for design 

 wave conditions. The sea-side section suffered severe damage with the highest 

 waves, but damage <10 percent for (H mo ) i < 20 ft . Results from Plan 1 indi- 

 cated the structure might be stable with smaller armor stones placed on the 

 middle section of the harbor side.
