Appendix F
Tables of Wave Parameters
and Water Levels by Storm
at Harbor Side Storm Surge
Stations
Tables of wave and wind parameters and water levels corresponding to the
maximum water level for each storm are provided for each storm surge station
along the south side of Cabras Island. Offshore wave heights are the deepwater
significant wave heights calculated outside the entrance to Apra Harbor. The
offshore wave heights and wind speeds correspond to peak water level at the
storm surge station and may not be the maximum wave heights and wind speeds
during the storm. Local significant wave heights include waves due to diffraction
through the entrance to Apra Harbor and waves generated locally inside the
harbor.
Total water level includes local storm surge, a tide level of mean high water,
and incident and reflected significant wave height at the station. The reference
datum is mean sea level. Total water level is the maximum level reached when a
significant wave representing the combined effect of diffracted and locally-
generated waves impacts the commercial dock and other areas along the south
side of Cabras Island. Thus, the total water level is only reached intermittently by
the higher waves during the most intense part of the storm relative to Apra

All waves and water levels are in feet in all tables in this appendix. To convert feet to meters,
multiply by 0.3048.
