In this paper, the long-term statistical properties of wave height in an id
ealized square harbor with a partial opening are studied. The incident wave
s are propagated into the harbor numerically by the finite/infinite element
method using three different wave models: (1) monochromatic wave train, (2
) long-crested random wave train, and (3) short-crested random wave train.
This study shows that for a given incident wave, the wave height in the har
bor is affected by the wave model used. For long-term estimation of wave he
ight exceedance probability, it is recommended that the waves be propagated
into the harbor using the random wave model, and that wave heights be comp
uted by use of the Rayleigh probability distribution.
