III. EXAMPLE PROBLEMS 



Example problems are presented to illustrate the steps required for manual 

 or computer computation. The examples indicate the relative importance of the 

 breakwater design variables on the magnitude of V. 



*************** EXAMPLE PROBLEM 1*************** 



GIVEN ; Four rubble-mound offshore breakwaters have the design conditions 

 illustrated in Figure 6. 



FIND ; V, assuming a monochromatic wave height of 8.0 feet (2.44 meters) at 

 the structure. 



SOLUTION ; Manual computation is illustrated in this example.
