APPENDIX C: WAVE DATA FOR GAGE 3.11 1. Wave data summaries for Gage 111 are presented for 1989 and for 1985 through 1989 in the following forms: Daily Hmo and TP 2. Figure Cl displays the individual wave height and peak spectral wave period values along with the monthly mean values. Joint Distributions of H. and Tp 3. Annual and monthly joint distributions tables are presented in Tables Cl and C2, and data for 1985 through 1989 are in Tables C3 and C4. Each table gives the frequency (in parts per 1,) for which the wave height and peak period were within the specified intervals; these values can be converted to percentages by dividing by 1. Marginal totals are also included. The row total gives the total number of observations out of 1, that fell within each specified peak period interval. The column total gives the number of observations out of 1, that fell within each specified wave height interval. Cumulative Distributions of Wave Height 4. Annual and monthly wave height distributions for 1989 are plotted in cumulative form in Figures C2 and C3. Data for 1985 through 1989 are in Figure C4. Peak Spectral Wave Period Distributions 5. Annual and monthly peak wave period, TP, distribution histograms for 1989 are presented in Figures C5 and C6. in Figure C7. Data for 1985 through 1989 are Cl
Persistence of Wave Heights 6. Table C5 shows the number of times in- 1989 when the specified wave height was qualed or exceeded at least once during each day for the duration (consecutive -days). Data for 1985 through 1989 are given in Table C6. An example is shown below: Height Consecutive Day(s)-or Longer - M 1 2 3 4 5 6 7 8 9 13 11 12 13 14 15 16 17 18 19+.5 18 15 14 13 12-11 -1 9 8 7 1. 5 34 24 21 18 14 12 8 7 3 2 1.5 41 19 8 6 2 1 2. 22 9 5 1 2.5 1 5 2 3. 6 1 3.5 1 4. 1 This example indicates that wave heights equaled or exceeded 1. m 5 times for at least 1 day; 34 times for at least 2 days; 24 times for at least 3 days, etc. Therefore, on 16 occasions the height equaled or exceeded 1. m for 1 day exactly (5-34 = 16); on 1 occasions for 2 days; on 3 occasions for 3 days, etc. Note that the height exceeded 1 m 5 times for 1 day or longer, while heights exceeded.5 m only 18 times for this same duration. This change in durations occurred because the longer durations of lower waves may be interspersed with shorter, but more frequent, intervals of higher waves. For example, one of the times that the wave heights exceeded.5 m for 16 days may have represented 3 times the height exceeded 1 m for shorter durations. Spectra 7. Monthly spectra for the offshore Waverider buoy (Gage 111) are presented in Figure C8. The plots show "relative" energy density as a function of wave frequency. These figures summarize the large number of spectra for each month. The figures emphasize the higher energy density associated with storms as well as the general shifts in energy density to different frequencies. As used here, "relative" indicates the spectra have been smoothed by the three-dimension surface drawing routine. Consequently, extremely high- and lpw-qnergy density values are modified to produce a smooth C2
surface. The figures are not intended for quantitative measurements; howev. er, they do provide the energy density as a function of frequency relative to t :e other spectra for the month. 8. Monthly and annual wave statistics for Gage Ill for 1989 and for 1985 through 1989 are presented in Table C7. 9. Figure C9 plots monthly time-histories of wave height and period.

APPENDIX D: WAVE DATA FOR GAGE 625 1. Wave data summaries for Gage 625 are presented for 1989 and for 198 through 1989 in the following forms: Daily Hmo and TP 2. Figure Dl displays the individual wave height and peak spectral wave period values along with the monthly mean values. Joint Distributions of Hmo and TP 3. Annual and monthly joint distributions tables are presented in Tables D1 and D2, and data for 198 through 1989 are in Tables D3 and D4. Each table gives the frequency (in parts per 1,) for which the wave height and peak period were within the specified intervals; these values can be converted to percentages by dividing by 1. Marginal totals are also included. The row total gives the total number of observations out of 1, that fell within each specified peak period interval. The column total gives the number of observations out of 1, that fell within each specified wave height interval. Cumulative Distributions of Wave-Height 4. Annual and monthly wave height distributions for 1989 are plotted in cumulative form in Figures D2 and D3. Data for 198 through 1989 are in Figure D4. Peak Spectral Wave Period Distributions 5. Annual and monthly peak wave period, Tp, distribution histograms for 1989 are presented in Figures D5 and D6. Data for 198 through 1989 are in Figure D7. DI
Persistence of Wave Heights 6. Table D5 shows the number of times in 1989 when the specified wave height was equaled or exceeded at least once -during each day for the duration (consecutive days). Data for 198 through 1989 are given in Table D6. An example is shown below: Height Consecutive Day(s) or Longer m 1 2 3 4 5 6 7 8 9 1 11 12 13 14 15 16 17 18 19+.5 18 15 14 13 12 11 1 9 8 7 1. 5 34 24 21 18 14 12 8 7 3 2 1.5 41 19 8 6 2 1 2. 22 9 5 1 2.5 1 5 2 3. 6 1 3.5 1 4. 1 This example indicates that wave heights equaled or exceeded 1. m 5 times for at least 1 day; 34 times for at least 2 days; 24 times for at least 3 days, etc. Therefore, on 16 occasions the height equaled or exceeded 1. m for 1 day exactly (5-34 = 16); on 1 occasions for 2 days; on 3 occasions for 3 days, etc. Note that the height exceeded 1 m 5Qtimes for 1 day or longer, while heights exceeded.5 m only 18 times for this same duration. This change in durations occurred because the longer durations of lower waves may be interspersed with shorter, -but more frequent, intervals of higher waves. For example, one of the times that the wave heights exceeded.5 m for 16 days may have represented 3 times the height exceeded 1 m for shorter durations. Spectra 7. Monthly spectra for the offshore Waverider buoy (Gage 625) are presented in Figure D8. The plots show "relative" energy density as a function of wave frequency. These figures summarize the large number of spectra for each month. The figures emphasize the higher energy- density associated with storms as well as the general shifts in energy density to different frequencies. As used here, "relative" indicates the spectra have been smoothed by the three'dimension surface drawing routine. Consequently, extremely high- and low-energy density values are-modified to produce & smooth D2
surface. The figures are not intended for quantitative measurements; however, they do provide the energy density as a function of frequency relative to the other spectra for the month. 8. Monthly and annual wave statistics for Gage (25 for 1989 and for 198 through 1989 are presented in Table D7. 9. Figure D9 plots monthly time-histories of wave height and period. D3

Figure El displays the individual wave height and peak spectral wave period values along with the monthly mean values. Joint Distributions of Hmo and Tp 3. Annual and monthly joint distributions tables are presented in Tables El and E2, and data for 198 through 1989 are in Tables E3 and E4. Each table gives the frequency (in parts per 1,) for which the wave height and peak period were within the specified intervals; these values can be converted to percentages by dividing by 1. Marginal totals are also included. The row total gives the total number of-observations out of 1, that fell within each specified peak period interval. The column total gives the number of observations out of 1, that fell within each specified wave height interval. Cumulative Distributions of Wave Height 4. Annual and monthly wave height distributions for 1989 are plotted in cumulative form in Figures E2 and E3. Figure E4. Data for 198 through 1989 are in Peak Spectral Wave Period Distributions 5. Annual and monthly peak wave period, TP, distribution histograms for 1989 are presented in Figures E5 and E6. in Figure E7. Data for 198 through 1989 are El
Persistence-of Wave Heights 6. Table E5 shows the number of times in 1989 when the specified wave height was equaled -or exceeded at least once during each day for the duration (consecutive days). Data for 198 through 1989 are given in Table E6. An example is shown below: Height Consecutive Day(s) or Longer m 1 2 3 4 5 6 7 8 9 1 11 12 13 14 15 16 17 18 19+.5 18 15 14 13 12 11 1 9 8 7 1. 5 34 24 21 18 14 12 8 7 3 2 1.5 41 19 8 6 2 1 2. 22 9 5 1 2.5 1 5 2 3. 6 1 3.5 1 4. 1 This example indicates that wave heights equaled or exceeded 1. m 5 times for at least 1 day; 34 times for at least 2 days; 24 times for at least 3 days, etc. Therefore, on 16 occasions the height equaled or exceeded 1. m for 1 day exactly (5-34 = 16); on 1 occasions for 2 days; on 3 occasions for 3 days, etc. Note that the height exceeded I m 5 times for 1 day or longer, while heights exceeded.5 m only 18 times for this same duration. This change in durations occurred because the longer durations of lower waves may be interspersed with shorter, but more frequent, intervals of higher waves. For example, one of the times that the wave heights exceeded.5 m for 16 days may have represented 3 times the height exceeded 1 m for shorter durations. Spectra 7. Monthly spectra for the offshore Waverider buoy (Gage 645) are presented in Figure E8. The plots show "relative" energy density as a function of wave frequency. These figures summarize the large number of spectra for each month. The figures emphasize the higher energy density associated with storms as well as the general shifts in energy density to different frequencies. As used here, "relative" indicates the spectra have been smoothed by the three-dimension surface drawing routine. Consequently, extremely high- and low-energy density values are modified to produce a smooth E2
surface. The figures are not intended for quantitative measurements; however, they do provide the energy density as a function of frequency relative to the other spectra for the month. 8. Monthly and annual wave statistics for Gage 645 for 1989 and for 198 through 1989 are presented in Table E7. 9. Figure E9 plots monthly time-histories of wave height and period. E3
