20. ABSTRACT (Xrorrtlaue on nv 



aide tf naceaoary and Identify by block number) 



An irregular wave technique based on a method developed by Goda (1975) and the SPM method for predicting 



nearshore wave height are compared with wave gage measurements from the CERC Field Research Facility. The 



SPM method is a classical monochromatic approach, while the irregular wave technique attempts to represent 

 the actual distribution of ocean waves. 



These two techniques have certain limitations and ranges of applicability. Comparisons with field data 

 will better define the limits and proper use for these techniques. The performance of the models is evalu- 

 ated for a variety of wave conditions and water depths.
