Modeling Breaking Waves and Wave-induced Currents with Fully Nonlinear Boussinesq Equations
نویسندگان
چکیده
A Boussinesq-type wave model is developed to numerically investigate the breaking waves and wave-induced currents. All the nonlinear terms are retained in the governing equations to keep fully nonlinearity characteristics and it hence more suitable to describe breaking waves with strong nonlinearity in the nearshore region. The Boussinesq equations are firstly extended to incorporate wave breaking, moving shoreline and bottom friction, and then solved numerically using finite difference method. Using well documented experimental data as a reference, numerical experiments are conducted to investigate the effect of tunable parameter values on the computed results. The developed model is used to simulate breaking waves and wave-induced currents over complex bathymetries and the numerical results are compared against the measurements. Key-Words: Breaking waves, Wave-induced currents, Boussinesq-type wave model, Numerical simulation.

Nearshore Wave Modeling with High-Order Boussinesq-Type Equations
The accuracy of using high-order Boussinesq-type models as compared to the typical order models is examined in this paper. The high-order model used is the two-layer model of Lynett and Liu in 2004, which captures both linear and nonlinear wave evolution up to kh 6. The physical situations examined all involve nearshore breaking, and an eddy-viscosity type breaking model is adopted for the two-...
متن کاملNumerical modelling of induced rip currents by discontinuous submerged breakwaters
Submerged breakwaters are one of the shore protective structures. Any discontinuity in these breakwaters causes changes on current parameters including speed and water surface profile. In this paper, discontinuous submerged breakwaters were modelled to investigate the changes in the wave and flow pattern.To investigate the phenomenon, three models including a shore with constant slope, a shore ...
متن کاملA fully nonlinear Boussinesq model for surface waves. Part 1. Highly nonlinear unsteady waves
Fully nonlinear extensions of Boussinesq equations are derived to simulate surface wave propagation in coastal regions. By using the velocity at a certain depth as a dependent variable (Nwogu 1993), the resulting equations have significantly improved linear dispersion properties in intermediate water depths when compared to standard Boussinesq approximations. Since no assumption of small nonlin...

In this paper, we focus on the implementation and verification of an extended Boussinesq model for surf zone hydrodynamics in two horizontal dimensions. The time-domain numerical model is based on the fully nonlinear Boussinesq equations. As described in Part I of this two-part paper, the energy dissipation due to wave breaking is modeled by introducing an eddy viscosity term into the momentum ...

This paper describes the numerical model BOUSS-WMH (BOUSSinesq Wave Model for Harbours), a finite element model for nonlinear wave propagation near shore and into harbors. It is based upon an extended version of the Boussinesq equations to which terms were added to generate regular or irregular waves inside the numerical domain, absorb outgoing waves, partially reflect waves at physical boundar...
