BREAKING OF IRREGULAR WAVES ON A SLOPE

[摘要] Breaking condition of irregular waves on a slope is studied through a series of labolatory experiment of bichromatic waves. First, breaking condition of individual waves defined by zero-down crossing method is compared with breaking condition of regular waves. An emperical formula is proposed to take into account of the influence of both the depth and width of the following trough. Then it is shown that the breaking condition of regular waves can be applied succesfully when the individual waves are properly defined by paying attention to the nature of the wave crests. Finally these results obtained from the laboratory experiment are tested against the field data with reasonable success.
