dc.descriptionLong-period wave data have been collected at an offshore wave gauge and seven harbor gauges for over 8 years in the Los Angeles/Long Beach Harbor region. These data are being used in studies for the design of expansion of the harbors. In particular, the data have been used to select long-period spectra for reproduction in a physical model of the harbors. The analysis of prototype wave data indicated correlation between the long-wave spectrum and the short-wave spectrum. Information was examined to determine the effect of the source of the short-period waves (Southern Hemisphere swell, hurricanes, or winter storms, typically from the west) on the nature of the long-period component of the waves. Relationships between the origin of the wave energy and long-wave period were determined. Wave statistics were used to interpret effects of the energy level on the wave transformation into the harbors and correlate long-wave and short-wave spectra. Examination of a 5- to 22-sec short-wave period and a 30- to 400-sec long-wave period indicated correlation of smaller short-wave periods with smaller long-wave periods, and larger short-wave periods with larger long-wave periods. Observations of moored-ship motion level was correlated to long-wave energy in a harbor basin.-
