| Research Abstract |
Ocean wave database in Japan is constructed on regular field observations. Number of locations and length of period are limited because the data is based on observations. Nowadays, X-band marine radars and ocean wave models can be applied for collecting ocean wave information. Three approaches are tried in this study : hardware and software improvements of an X-band marine radar for higher accuracy ; introduction of wave transmissibility to an ocean wave model for improvement of onshore wave estimation due to topography from offshore waves to onshore ; and, introduction of the maximum wave height estimation in the ocean wave model. These approaches will be useful for building a multi-parameter coastal wave database.
