Wave Fields and Nearshore Currents in the Coastal Region Opposite San Mauro Cilento (Italy)
In this paper in order to simulate nearshore currents in computational domains representing the
complex morphology of real coastal regions we use a model based on a contravariant integral form of the fully
nonlinear Boussinesq equations (FNBE). The contravariant integral form, in which Christoffel symbols are
absent, of the continuity equation does not contain the dispersive term. The Boussinesq equation system is
numerically solved by a hybrid finite volume-finite difference scheme. The wave breaking is represented by
discontinuities of the weak solution of the integral form of the nonlinear shallow water equations (NSWE). The
capacity of the proposed model to correctly simulate the wave train propagation on a highly distorted grid is
verified against test case present in the literature. The simulation of wave fields and nearshore currents in the
coastal region, opposite San Mauro Cilento (Italy) in presence of a system of T-head groins, is numerically
reproduced by using the proposed model.
