A team of engineers would like to determine the wave runup for a quarrystone breakwater with the following conditions:
Equivalent unrefracted deepwater wave height = 3 m
Water depth at the structure toe = 13 m
Wave period = 6 seconds
Structure slope cot theta = 1.5
Height of core = 9 m
The team would like to reduce the wave runup by using either a tetrapod or tribar concrete armor in place of the quarrystone. For the given conditions above, determine whether the engineers can achieve their goal and by what percentage would you expect runup to be reduced for the tetrapod and tribar armors
