• At many ports throughout JAPAN, port disturbances caused by long-period oscillations are currently posing problems at many harbors and fishing ports but many questions about the mechanism of port disturbances are still remained. In the present study, phenomena were analyzed by field observations and factors were analyzed numerically to clarify the mechanism of the port disturbance generation accompanying the advance of long-period waves into ports. The results are as follows; (1) The port disturbances at Kumaishi Fishing Port could be attributed to resonances between the natural periods of this port in Modes 1 through 3 and the long-period components of incoming waves. (2) The results of observations and numerical analyses show, if a port has a natural beach and water passage, the resonance phenomenon reduces the amplitude amplification factor.
