the two numerical models (surge and wave) were the main inputs to the physical 

 model's overtopping rate equation which produced the overtopping rate for each 

 required time-step. The water volume due to overtopping was then routed 

 through the Roughans Point area, and a maximum stage was calculated for each 

 event. Finally, a stage-frequency curve was created for flood levels induced 

 by wave overtopping. 



Organization of Report 



7. This report is structured as follows. Part II is a description of 

 the probability model. Modeling of the surge plus tide events is discussed 

 in Part III, including calibration and verification of the storm surge model. 

 Part IV is a description of the numerical wave modeling. The methods for cal- 

 culating the overtopping rate time-histories and routing the flood through 

 Roughans Point are discussed in Part V. The construction of stage-frequency 

 curves is explained in Part VI. Part VII contains discussion of the results, 

 including an estimate of the error in the stage-frequency curves. Because of 

 the large volume of results generated by the numerical models, time-histories 

 of ocean water levels, waves, winds, overtopping rates, and Roughans Point in- 

 terior flood levels are not provided in this report but were given to MED on 

 computer tape.
