An analytical model of the evolution of a Stokes wave and its two Benjamin–Feir sidebands on nonuniform unidirectional current [PDF]
Nonlinear Processes in Geophysics, 2015 An analytical weakly nonlinear model of the Benjamin–Feir instability of a Stokes wave on nonuniform unidirectional current is presented. The model describes evolution of a Stokes wave and its two main sidebands propagating on a slowly varying steady ...

Wave‐current interactions in a wave‐dominated tidal inlet [PDF]
Journal of Geophysical Research: Oceans, 2013 Wave‐current interactions play a major role in the dynamics of shallow tidal inlets. This study investigates these interactions at a natural inlet, with a strong focus on current‐induced changes on wave propagation. The analysis of hydrodynamic data collected at the Albufeira lagoon, Portugal, revealed spatiotemporal variations of water levels and wave

Numerical Modelling of the Effects of the Gulf Stream on the Wave Characteristics
Journal of Marine Science and Engineering, 2021 The influence of the Gulf Stream on the wind wave characteristics is investigated. Wave–current interaction inside the current field can result in significant inhomogeneities of the wave field that change the wave spectrum and wave statistics. This study

Analysis of the Scattering Characteristics of Sea Surface with the Influence from Internal Wave
Leida xuebao, 2015 The internal wave travels beneath the sea surface and modulate the roughness of the sea surface through the wave-current interaction. This makes some dark and bright bands can be observed in the Synthetic Aperture Radar (SAR) images.

Nonlinear Wave–Current Interactions in Shallow Water [PDF]
Studies in Applied Mathematics, 2016 We study here the propagation of long waves in the presence of vorticity. In the irrotational framework, the Green–Naghdi equations (also called Serre or fully nonlinear Boussinesq equations) are the standard model for the propagation of such waves.

Effect of Wavelength on Turbine Performances and Vortical Wake Flows for Various Submersion Depths
Journal of Marine Science and EngineeringWhen tidal turbines are deployed in water areas with significant waves, assessing the surface wave effects becomes imperative. Understanding the dynamic impact of wave–current conditions on the fluid dynamic performance of tidal turbines is crucial. This
