波浪監視計の改良と活用範囲の拡張

抄録

This paper introduced the newly developed Real-Time Shallow Wave Meter. The Real-Time Shallow Wave Meter is able to observe shallow water wave heights and periods with sufficient accuracy by measuring seabed pressure fluctuations. Observed data are transmitted to the on-land personal computer by wireless, and are displayed on it at the same time. When the wave height exceeds a critical value, the warning signal is displayed.
Following improvements was recently conducted to the system.
(1) Composite Cable for mooring and data communication was developed.
(2) Application to the offshore observation was realized by using movable telephone system.
(3) Application to the directional wave and current measurement was enabled.
