TA7 W34 no.CERC-95-10 Appendix C Wave Data for Gage 111 Wave data summaries for Gage 111 for 1992 and for 1985 through 1992 are presented in the following pages: Daily no and Tp Figure C1 displays the individual wave height H,,,, and peak spectral wave period qT, values, along with the monthly mean values. Joint Distributions of ieee and ’p Annual and monthly joint distribution tables are presented in Tables C1 and C2, and data for 1985 through 1992 are in Tables C3 and C4. Each table gives the frequency (in parts per 10,000) for which the wave height and peak period were within the specified intervals; these values can be converted to percentages by dividing by 100. Marginal totals are also included. The row total gives the number of observations out of 10,000 that fell within each specified peak period interval. The column total gives the number of observations out of 10,000 that fell within each specified wave height interval. Cumulative Distributions of Wave Height Annual and monthly wave height distributions for 1992 are plotted in cumulative form in Figures C2 and C3. Data for 1985 through 1992 are plotted in Figure C4. Peak Spectral Wave Period Distributions Annual and monthly peak wave period T,, distribution histograms for 1992 are presented in Figures C5 and C6. Data for 1985 through To92 are presented in Figure C7. Appendix C Wave Data for Gage 111 C1 Persistence of Wave Heights Table C5 shows the number of times in 1992 when the specified wave height was equaled or exceeded at least once during each day for the duration (consecutive days). Data for 1985 through 1992 are averaged and given in Table C6. An example is shown below: Height Consecutive Day(s) or Longer 10 11 12 13 #14 15 14 13 12 34 24 21 18 14 12 NOE Be iG vwmieh att OPS tl 2 5 1 1 This example indicates that wave heights equaled or exceeded 1.0 m 50 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 1.0 m for 1 day exactly (50 - 34 = 16); on 10 occasions for 2 days; on 3 occasions for 3 days, etc. Note that the height exceeded 1 m 50 times for 1 day or longer, while heights exceeded 0.5 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 0.5 m for 16 days may have represented three times the height exceeded 1 m for shorter durations. Spectra Monthly spectra for the pressure gage (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-dimensional surface drawing routine. Consequently, extremely high- and low-energy density values are modified to produce a smooth 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. Monthly and annual wave statistics for Gage 111 for 1992 and for 1985 through 1992 are presented in Table C7. Figure C9 plots monthly time histories of wave height and period.

Joint Distributions of Hino and Tp Annual and monthly joint distribution tables are presented in Tables D1 and D2, and data for 1980 through 1992 are in Tables D3 and D4. Each table gives the frequency (in parts per 10,000) for which the wave height and peak period were within the specified intervals; these values can be converted to percentages by dividing by 100. Marginal totals are also included. The row total gives the number of observations out of 10,000 that fell within each specified peak period interval. The column total gives the number of observations out of 10,000 that fell within each specified wave height interval. Cumulative Distributions of Wave Height Annual and monthly wave height distributions for 1992 are plotted in cumulative form in Figures D2 and D3. Data for 1980 through 1992 are plotted in Figure D4. Peak Spectral Wave Period Distributions Annual and monthly peak wave period 7, distribution histograms for 1992 are presented in Figures DS and D6. Data for 1980 through 1992 are presented in Figure D7. Appendix D Wave Data for Gage 625 D1 Persistence of Wave Heights Table DS shows the number of times in 1992 when the specified wave height was equaled or exceeded at least once during each day for the duration (consecutive days). Data for 1980 through 1992 are averaged and given in Table D6. An example is shown below: Height Consecutive Day(s) or Longer m : (mas 10 11 12 13 #14 15 14 13 12 34 26 21 18 14 12 WD 8 BG 2B 4 OS at 2 oO ui 1.0 1.5 2.0 2.9 3.0 3.5 4.0 5 1 1 This example indicates that wave heights equaled or exceeded 1.0 m 50 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 1.0 m for 1 day exactly (SO - 34 = 16); on 10 occasions for 2 days; on 3 occasions for 3 days, etc. Note that the height exceeded 1 m 50 times for 1 day or longer, while heights exceeded 0.5 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 0.5 m for 16 days may have represented three times the height exceeded 1 m for shorter durations. Spectra Monthly spectra for the offshore staff gage (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-dimensional surface drawing routine. Consequently, extremely high- and low-energy density values are modified to produce a smooth 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. Monthly and annual wave statistics for Gage 625 for 1992 and for 1980 through 1992 are presented in Table D7. Figure D9 plots monthly time histories of wave height and period.

Joint Distributions of Hino and Tp Annual and monthly joint distribution tables are presented in Tables E1 and E2, and data for 1980 through 1992 are in Tables E3 and E4. Each table gives the frequency (in parts per 10,000) for which the wave height and peak period were within the specified intervals; these values can be converted to percentages by dividing by 100. Marginal totals are also included. The row total gives the number of observations out of 10,000 that fell within each specified peak period interval. The column total gives the number of observations out of 10,000 that fell within each specified wave height interval. Cumulative Distributions of Wave Height Annual and monthly wave height distributions for 1992 are plotted in cumulative form in Figures E2 and E3. Data for 1980 through 1992 are plotted in Figure E4. Peak Spectral Wave Period Distributions Annual and monthly peak wave period 7. distribution histograms for 1992 are presented in Figures ES and E6. Data for 1980 through 1992 are presented in Figure E7. E1 Appendix E Wave Data for Gage 645 Persistence of Wave Heights Table E5 shows the number of times in 1992 when the specified wave height was equaled or exceeded at least once during each day for the duration (consecutive days). Data for 1980 through 1992 are averaged and given in Table E6. An example is shown below: Consecutive Day(s) or Longer 9 10 11 12 13 «+14 «15 34 24 21 18 14 12 we 8 6 2 4 O 3 1 2 5 1 1 This example indicates that wave heights equaled or exceeded 1.0 m 50 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 1.0 m for 1 day exactly (50 - 34 = 16); on 10 occasions for 2 days; on 3 occasions for 3 days, etc. Note that the height exceeded 1 m 50 times for 1 day or longer, while heights exceeded 0.5 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 0.5 m for 16 days may have represented three times the height exceeded 1 m for shorter durations. Spectra Monthly spectra for the offshore staff gage (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-dimensional surface drawing routine. Consequently, extremely high- and low-energy density values are modified to produce a smooth 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. Monthly and annual wave statistics for Gage 645 for 1992 and for 1980 through 1992 are presented in Table E7. Figure E9 plots monthly time histories of wave height and period.
