2. A number of different revetment configurations were constructed in 

 front of the Roughans Point seawall, and the wall crest elevation was varied 

 to determine their ability to reduce wave overtopping of the wall. Results of 

 this effort have yielded specific information to help solve the Roughans Point 

 site-specific problem and general information which will help to improve cur- 

 rent techniques for calculating irregular wave overtopping rates given in the 

 SPM (1984). A simple way to quantify the overtopping potential of the various 

 seawall/revetment configurations is presented. 



Purpose 



3. The purposes of this two-dimensional (2-D) wave overtopping study 

 were to: 



a. Evaluate the effectiveness of 10 proposed seawall/revetment 

 configurations at reducing wave overtopping of the Roughans 

 Point seawall. 



b. Determine a simple method to predict wave overtopping of the 

 Roughans Point seawall.
