Abstract

The extended Boussinesq equations derived by Madsen and Sørensen (1992) and Nwogu (1993) significantly improve the linear dispersive properties of long-wave equations in the intermediate water depth, making it applicable to describe wave transformation from relatively deep to shallow water. In this study, two numerical models (MS model and N model) based on the extended equations are developed. The governing equations are discretized using a fourth-order predictor-corrector scheme for time stepping and the first-order spatial derivative to fourth-order accuracy. The models are applied to compute wave propagating over a submerged dike and predictions are compared with experimental data. The numerical accuracy by MS model and N model is discussed.
