沿岸波浪と海難の関係(日本航海学会第18回講演会)

抄録

Nearshore waves aroused by the strong onshore wind in the case of typhoon or of gusty wind due to frontal passage of cyclone are marked developed in the surf zone of open coast or near the river entrance, which demands the warning to fishing vessels. We can distinguish two types of them, i.e. (1) Open coast onshorewind type, (2) Rivermouth crossed-wave type. Some examples are illustrated as those, (i) sea-disaster of Doya Maru (due to typhoon Maris), and (ii) sea disaster of Hyoei Maru (due to river mouth pyramidal wave.)
