Wave–Current Interactions in a Wind-jet Region [PDF]

Ocean Science, 2018
Abstract. Wave–Current Interactions (WCIs) are investigated. The study area is located at the northern margin of the Ebro Shelf (northwestern Mediterranean Sea), where episodes of strong cross-shelf wind (wind jets) occur. The aim of this study is to validate the implemented coupled system and investigate the impact of WCIs on the hydrodynamics of a ...

A Study of Wave Dissipation Rate and Particles Velocity in Muddy Beds

Geosciences, 2019
The interactions between free surface waves and layers of cohesive sediments including wave height attenuation and mud movement are of great importance in coastal and marine engineering.

A Nonlinear Coupled-Mode Model for Waves Propagating in Vertically Sheared Currents in Variable Bathymetry—Collinear Waves and Currents

Fluids, 2019
A novel coupled-mode model is developed for the wave–current–seabed interaction problem, with application in wave scattering by non-homogeneous, sheared currents over general bottom topography.

COMPARISON OF WAVE-CURRENT INTERACTION FORMULATION USING THE POLCOMS-WAM WAVE-CURRENT MODEL [PDF]

Coastal Engineering 2008, 2009
Ocean processes do not take place in isolation but interact with one another to form a complex system. This paper focuses on these processes by using and developing the POLCOMS-WAM model. The Stokes’ drift and radiation stress effect on currents have been included, following state of the art formulations. The system is evaluated in the NW Mediterranean

Iteration Coupling Simulation of Random Waves and Wave-Induced Currents

Journal of Applied Mathematics, 2012
A two-way coupling algorithm for wave-current interaction is developed and implemented into a nearshore circulation model to investigate the effects of fully wave-current interaction on irregular wave transformation over an elliptic shoal. The wave field

Nonlinear dispersion in wave-current interactions

Journal of Geometric Mechanics, 2022
Via a sequence of approximations of the Lagrangian in Hamilton's principle for dispersive nonlinear gravity waves we derive a hierarchy of Hamiltonian models for describing wave-current interaction (WCI) in nonlinear dispersive wave dynamics on free surfaces.

Stochastic Wave–Current Interaction in Thermal Shallow Water Dynamics [PDF]

Journal of Nonlinear Science, 2021
AbstractHolm (Proc R Soc A Math Phys Eng Sci 471(2176):20140963, 2015) introduced a variational framework for stochastically parametrising unresolved scales of hydrodynamic motion. This variational framework preserves fundamental features of fluid dynamics, such as Kelvin’s circulation theorem, while also allowing for dispersive nonlinear wave ...

Assessing the Impact of Wave–Current Interactions on Storm Surges and Waves during Cold Air Outbreaks in the Northern East China Sea

Journal of Marine Science and Engineering, 2021
Storm surges and disastrous waves induced by cold air outbreaks, a type of severe weather system, often impact the coastal economic development. Using the Climate Forecast System Reanalysis wind product and the Coupled Ocean–Atmosphere–Wave–Sediment ...

Re-Creating Waves in Large Currents for Tidal Energy Applications

Energies, 2017
Unsteady wave loading on tidal turbines impacts significantly the design, and expected life-time, of turbine blades and other key components. Model-scale testing of tidal turbines in the wave-current environment can provide vital understanding by ...
