In this paper, the shoreline and bottom modifications produced by the presence of a T-head groin are simulated. We present a model for the bottom-change simulation, composed by two sub-models: a two-dimensional phase-resolving model for the simulation of the variation of the fluid dynamic variables inside the wave period and that takes into account the undertow; a second morphodynamic sub-model for the simulation of the bottom changes, in which the suspended sediment concentration is calculated by means of the wave-averaged advection-diffusion equation. Both the fluid motion equation and the concentration equation are written in a new contravariant formulation. We simulate the velocity fields from deep water to the start of the surf-zone by a new integral contravariant form of the Fully Nonlinear Boussinesq Equations. We simulate the bed evolution dynamics by means of the contravariant formulation of the advection-diffusion equation for the suspended sediment concentration. A quasi three-dimensional approach is used to formulate the advective sediment transport terms in the advection-diffusion equation.
