Abstract This work aims to represent the dynamics of the wave propagation in the surf zone through a weakly dispersive fully nonlinear Boussinesq model. Since the breaking process introduces a huge amount of vorticity within the flow, the usually adopted hypothesis of potential flow has been removed here, and thus the momentum increase due to breaking has been modeled directly in terms of the vorticity field. The amount of vorticity introduced by the breaking process has been determined through an analogy with the hydraulic jump and the adoption of the concept of the roller. An accurate description of the effects of the surface roller has been reached using an or
