Water wave collapses over quasi-one-dimensional non-uniformly periodic bed profiles
Nonlinear water waves interacting with quasi-one-dimensional, non-uniformly
periodic bed profiles are studied numerically in the deep-water regime with the
help of approximate equations for envelopes of the forward and backward waves.
Spontaneous formation of localized two-dimensional wave structures is observed
in the numerical experiments, which looks essentially as a wave collapse.Comment: 4 pages, 4 figure
