Inter-Comparisons of Different Forms of Higher-Order Boussinesq Equations

Variational Boussinesq model for strongly nonlinear dispersive waves

“…Propagation over a submerged bar is known to test the nonlinearity and accurate dispersion of a wave model, as shown in experimental studies by Beji and Battjes [28], Luth et al [32], Ohyama et al [33], and Zou et al [34]. When waves propagate over the front slope of a bar, higher harmonic bound waves are introduced and the waves become higher and steeper.…”

“…Overall, the simulations give a good agreement with the measurement data. [34] This experiment was conducted by Zou et al [34] for two types of submerged bars. We refer to the first type as Case A which has a 1:10 front slope and 1:2 back slope, and Case B has 1:2 front slope and 1:10 back slope.…”
