TRANSFORMATION OF WAVES PASSING A SUBMERGED BAR

[摘要] This study investigates the transformation of nonbreaking waves that pass over a submerged longshore bar. An envelope for the occurrence of ^ transformation of nonbreaking waves is established and compared with existing information. Power spectral analyses are made of both the incident and transformed waves to determine quantitatively the change in wave characteristics. The conclusion is made that the transformation process is a nonlinear phenomenon occurring over the bar, but, in the deeper water in the lee of the bar, a combination of linear wave forms results.
