3 Conclusions 



Based on tests and results described herein, in which stone armor is 

 used on breakwater trunks and subjected to spectral wave attack, it is con- 

 cluded that: 



a. Armor stability is influenced by wave period with the lower 

 stabilities being observed at the longer wave periods in shallower 

 water. 



b. The lower stabilities generally occur for the more highly grouped 

 waves. 



c. Minimum stability coefficients observed herein are especially 

 significant in that they are less than the minimums presently 

 recommended for design.
