Response of the structure was recorded during and after each wave condition. 

 Photographs also were taken at seaside locations while the basin was flooded if 

 significant damage to the structure occurred during a wave condition. A detailed 

 inspection of the structure also was performed and effects of the waves on indi- 

 vidual units, toe buttress protection, and the general condition of the structure 

 were recorded. The basin was drained, and after-experiment photographs were 

 taken after all waves of the storm series were generated or the structure had 

 suffered significant damage. Before and after photographs are located in 

 Appendix A. 



Model Breakwater Construction 



Construction of the modeled section simulated prototype construction as 

 closely as possible. The core, bedding, and underlayer of material were dumped 

 by shovel, smoothed to grade, and compacted with hand trowels to simulate 

 consolidation that would have occurred due to wave action. 



The various model plans consisted of 8- and/or 11 -tonne Core-Locs placed in 

 the armor layer from Profile 4 to the breakwater head, and 6.25-tonne tetrapods
