APPENDIX B: WAVE DATA 



Wave data summaries for 1984 and climatological summaries for 1980 

 through 1984 are presented in this appendix. An explanation of the summary 

 formats is followed by a list of tables and figures, then the data for 

 gages 625, 620, and 615. Wave data are summarized in the following forms: 



a. Gage histories. Table Bl includes information about the gages, gage 

 installations, and major interruptions in the data collection. 

 Short interruptions in the operational status of the gage are not 

 mentioned. 



b. Time-histories. A continuous display of individual wave height and 

 peak spectral wave period values is plotted as a function of the 

 time throughout the year (Figures Bl, B20, and B33) . Gaps indicate 

 breaks in the data longer than 24 hr. 



£. Annual, seasonal, and monthly maxima, mean, and standard deviations 

 of wave height and peak period. The 1984 mean wave height and stan- 

 dard deviation, mean peak wave period and standard deviation, and 

 extreme wave heights are listed in Tables B2, B12, and B22 and are 

 plotted in Figures B2, B21, and B34. Combined statistics for 1980 

 through 1984 are given in Tables B7, B17, and B27 and are plotted in 

 Figures BU, B27, and B40. Also included in the tables is the total 

 number of observations obtained; at four observations per day, the 

 maximum number of observations per month (based on a 30-day period) 

 is 120. In the figures, the standard deviations are presented as 

 vertical bars originating at the mean value and extending to the 

 mean plus one standard deviation value. The extreme values are 

 plotted above. No extreme period values are presented. 



d. Joint distribution functions of wave height versus peak period. 

 Annual, seasonal, and monthly joint distribution tables are pre- 

 sented for 1984 in Tables B3-B5, B13-B15, and B23-B25; data for 1980 

 through 1984 are presented in Tables B8-B10, B18-B20, and B28-B30. 

 Each table gives the frequency (in parts per 1,000) for which the 

 wave height and peak period were within the specified intervals; 

 these values can be converted to percent by dividing by 10. 

 Marginal totals are also included. The raw total gives the total 

 number of observations out of 1,000 which fell within each specified 

 peak period interval. The column total gives the number of observa- 

 tions out of 1,000 which fell within each specified wave height 

 interval. 



e. Cumulative distributions of wave height. For each gage, annual, 

 seasonal, and monthly wave height distributions of 1984 are plotted 

 in cumulative form in Figures B3-B5, B22-B24, and B35-B37. Data for 

 1980 through 1984 are in Figures B12-B14, B28-B30, and B41-B43. 



f^. Peak spectral wave period distributions. Annual, seasonal, and 



monthly peak wave period T distribution histograms for 1984 are 



presented in Figures B6-B8, B25, B26, B38, and B39; data for 1980 

 through 1984 are in Figures B15-B17, B31, B32, B44, and B45.
