14. ABSTRACT
The Pago Pago Harbor embayment is an extensive, naturally protected harbor area. The embayment includes Pago Pago commercial
harbor, the principal harbor area of the Territory of American Samoa. To assist in planning for future harbor facility requirements, studies
of the wave response of alternative sites in Pago Pago Harbor embayment were conducted. The numerical model CGWAVE was used to
simulate the behavior of the Pago Pago Harbor embayment, including four alternative harbor sites. Model results were compared with
criteria for operational acceptability and with experience in the existing harbor to the extent possible. The effectiveness of proposed new
harbor areas for wind wave and swell protection often has little relationship to protection from oscillations. These two aspects of pier
operability were both considered in judging suitability of the alternative sites. Extreme wave and water level information for design is also
presented.
