title = "Coastal geomorphology model using boussonesq equation considering undertow effect",
abstract = "The undertow effect on coastal morphological modeling is studied. A fully nonlinear Boussinesq equation including horizontal vorticity produced by bottom shear stress is used for the prediction of flows. A depth-integrated sediment transport equation is coupled with the Boussinesq equation for the prediction of sediment transport. To solve these equations numerically, a fourth-order accurate finite volume method on the basis of a compact MUSCL TVD scheme is used, and the numerical fluxes are computed by the HLLC approximate Riemann solver. The coastal geomorphology model with and without horizontal vorticity effects is applied to surf zone, and the computed flow velocities are compared to measured data. When the vorticity effects are included the undertow flow profile shows closer agreement with measured data quantitatively and qualitatively. Lastly, an offshore bar migration by monochromatic wave is simulated and the contributions of the undertow effects are investigated.",
