Incident long wave conditions con- 

 sidered are given in Table 16. A fine 

 resolution in wave frequency was used over 

 the full range of possible resonant conditions 

 to ensure that all important peaks were 

 identified. A total of 468 periods were 

 considered. Only one approach direction is 

 included, since past studies have indicated 

 that harbor response is relatively insensitive 

 to incident long wave direction. This 

 direction represents a wave directly 

 approaching the harbor entrance from deep 

 water. 



One water level was tested. The tide 

 range at Kahului Harbor is relatively small, 

 with a mean range of 1.9 ft. Harbor wave 

 response is unlikely to vary much with water 

 level over this tidal range. The water level 

 was selected as mean lower low water, the 

 reference datum for bathymetric data.
