Surface gravity waves on randomly irregular floor and the telegrapher's equation
(American Institute of Physics, 2021-04)
The simplest model for the evolution of the mean-value of a surface gravity wave propagating in a random bottom has been connected with the telegrapher's equation. This analysis is based on the comparison of the mean-value ...
An integrable evolution equation for surface waves in deep water
(Iop Publishing Ltd, 2014-01-17)
In order to describe the dynamics of monochromatic surface waves in deep water, we derive a nonlinear and dispersive system of equations for the free surface elevation and the free surface velocity from the Euler equations ...
Gravity waves on a random bottom: exact dispersion-relation
(Taylor & Francis Ltd, 2021-05)
In a recent paper [Cáceres MO, Comments on wave-like propagation with binary disorder. J. Stat. Phys. 2021;182(36):doi.org/10.1007/s10 955-021-02699-0.], the evolution of a wave-like front perturbed by space-correlated ...
Experiments on generation of surface waves by an underwater moving bottom
(The Royal Society, 2015)
We report laboratory experiments on surface waves generated in a uniform fluid layer whose bottom undergoes an upward motion. Simultaneous measurements of the free-surface deformation and the fluid velocity field are focused ...
The modulational instability in deep water under the action of wind and dissipation
(Cambridge University Press, 2010-12-01)
The modulational instability of gravity wave trains on the surface of water acted upon by wind and under influence of viscosity is considered. The wind regime is that of validity of Miles' theory and the viscosity is small. ...

(Cambridge University Press, 2010-12-01)
The modulational instability of gravity wave trains on the surface of water acted upon by wind and under influence of viscosity is considered. The wind regime is that of validity of Miles' theory and the viscosity is small. ...
Stationary shapes for 2-d water-waves and hydraulic jumps
(2016)
A hydraulic jump is a physical phenomenon commonly observed in nature such as in open channel flows or spillways and is dependent upon the relation between the initial upstream fluid speed and a critical speed characterized ...
The modulational instability in deep water under the action of wind and dissipation
(Cambridge University Press, 2013)
Wave damping of a sloshing wave by an interacting turbulent vortex flow
(American Physical Society, 2020)
We report on the enhancement of the hydrodynamic damping of gravity waves at the surface of a fluid layer as they interact with a turbulent vortex flow in a sloshing experiment. Gravity surface waves are excited by oscillating ...
High gravity-wave activity observed in Patagonia, Southern America: generation by a cyclone passage over the Andes mountain range
(Wiley, 2012-07)
The Antarctic peninsula and Patagonia region (the south of South America) have recently been identified as the regions with the highest gravity-wave activity in the world. In this work, the generation and propagation of ...
