Abstract: Long period wave data have been collected at an offshore wave gage and system harbor gages for over eight years in the Los Angeles/Long Beach Harbor region. These 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. In particular, the data have been used to select long period spectra for reproduction in a physical model of the harbors. They included two storm conditions representative of storms from the west and a summer spectrum from the south. These long period spectra were used to program model wave generators and wave data were collected at locations in the model which corresponded to prototype gage locations. A comparison of model and prototype correaltion. Also long wave information short period waves (southern hemisphere swell, hurricanes, or winter storms) on the nature of the long period component of the waves. Wave statistics were used to interpret effects of energy level on wave transformation into the harbors and correlate long and short wave spectrum.
