PREFACE 



Design curves for the maximum breaker height in the surf zone for monochro- 

 matic waves (based on the work of Goda, 1970) are given in Section 7.12 of the 

 Shore Protection Manual (U.S. Army, Corps of Engineers, Coastal Engineering 

 Research Center, 1977). This report presents similar curves for the magnitude 

 and location of peak wave heights for irregular waves, based on the model of 

 Goda (1975) . This work was carried out as a part of the offshore breakwaters 

 for shore stabilization program of the U.S. Army Coastal Engineering Research 

 Center (CERC) . 



This report was prepared by William N. Seelig, Hydraulic Engineer, under 

 the general supervision of Dr. R.M. Sorensen, Chief, Coastal Processes and 

 Structures Branch.
