Extreme wave formation past a submerged circular sill: The role of linear spatial focusing and resonant trapping
E Renzi - Physics of Fluids, 2023 - pubs.aip.org
We investigate dispersive wave amplification past a submerged circular sill on an otherwise
flat seabed. This phenomenon is important because it can generate large-amplitude waves …
