Continuous seiche in bays and harbors

| Summary: | Seiches are often considered a transitory phenomenon wherein large
amplitude water level oscillations are excited by a geophysical event,
eventually dissipating some time after the event. However, continuous
small-amplitude seiches have been recognized which raises a question regarding the
origin of continuous forcing. We examine six bays around the Pacific where
continuous seiches are evident and, based on spectral, modal, and kinematic
analysis, suggest that tidally forced shelf resonances are a primary driver of
continuous seiches. |
