PART IV: CONCLUSIONS 



22. Based on tests and results described herein in which dolos armor is 

 used to overlay existing tribars on breakwater trunks subjected to breaking 

 waves with a direction of approach of 90 deg, it is concluded that: 



a. The stability coefficient is independent of sea-side structure 

 slope for slopes of IV on I,5H and IV on 2H. 



b. Stability showed some dependency on both d/L and H/d with 

 minimum stability occurring at the lower values of d/L and 

 higher values of H/d , i.e. longer wave periods in shallower 

 water. 



£. The minimum stability coefficient observed significantly 

 exceeds that obtained for new construction.
