Abstract
Observed coastal wave data are very important information for a port planning, design, construction, operation and management. Nevertheless, it is difficult to install wave gauges off all the ports and harbors due to financial and social restrictions. In the case of the Miyazaki-Port, faced to the Pacific Ocean and located at the southeast coast of the Kyusyu Island of Japan, wave information had to be obtained from a wave gauge off the Hososhima-Port, 60km far from the Miyazaki-Port, as the old on-site wave gauge got unable to continue observation. This paper introduced a newly developed a real-time wave information system of the Miyazaki-Port using the observed directional wave spectrum data off the Hososhima-Port by the way of spectrum correlation analysis.
