Particle Trajectories Beneath Fully Nonlinear Waves Generated by Horizontal Seabed Motion
João Vitor P. Poletto, David Andrade, Marcelo V. Flamarion +1
We investigate fully nonlinear water waves and fluid-particle dynamics generated by the horizontal motion of a seabed obstacle with prescribed time-dependent velocity. The governin…
The Kadomtsev-Petviashvili equation in conformal variables for waves over topography
David Andrade, Marcelo V. Flamarion
The conformal mapping approach is a well established technique for solving the Euler equations for potential flows with one spatial dimension. In this work, we extend this framewor…
Full Euler equations for waves generated by vertical seabed displacements
Joao Vitor Parada Poletto, David Andrade, Marcelo V. Flamarion +1
We present a novel numerical method for simulating the generation and propagation of surface gravity waves by vertical seabed displacements. The cornerstone of our method is the co…
Wave-by-wave forecasts in directional seas using nonlinear dispersion corrections
Eytan Meisner, Mariano Galvagno, David Andrade +2
We develop a new methodology for the deterministic forecasting of directional ocean surface waves, based on nonlinear frequency corrections. These frequency corrections can be pre-…
A theoretical study of the air-sea drag-saturation in very strong winds
Michael Stiassnie, David Andrade
The goal of this note is to provide a theoretical explanation for the saturation of the drag coefficient in strong wind conditions. The hydrodynamic model under consideration takes…
The nonlinear Benjamin-Feir instability -- Hamiltonian dynamics, primitive breathers, and steady solutions
David Andrade, Raphael Stuhlmeier
We develop a general framework to describe the cubically nonlinear interaction of a unidirectional degenerate quartet of deep-water gravity waves. Starting from the discretised Zak…
A three dimensional Dirichlet-to-Neumann operator for waves over topography
David Andrade, André Nachbin
Surface water waves are considered propagating over highly variable non-smooth topographies. For this three dimensional problem a Dirichlet-to-Neumann (DtN) operator is constructed…
