Modeling Breaking Waves and Wave-induced Currents with Fully Nonlinear Boussinesq Equations
Authors: ,
Abstract: 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.
