title: Water wave collapses over quasi-one-dimensional nonuniformly periodic bed profiles.
abstract: Nonlinear water waves interacting with quasi-one-dimensional nonuniformly 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.
