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.317202031720209199https://www.wseas.org/multimedia/journals/fluid/2020/a185113-261.pdf10.37394/232013.2020.15.9http://www.wseas.org/multimedia/journals/fluid/2020/a185113-261.pdf10.1051/itmconf/20192402011Cannata G., Gallerano F., Palleschi F., Petrelli C., Barsi L., Three-dimensional numerical simulation of the velocity fields induced by submerged breakwaters, International Journal of Mechanics, Vol. 13, 2019, pp. 1–14. 10.2495/afm160181Cannata G., Petrelli C., Barsi L., Camilli F., Gallerano F. 3D free surface flow simulations based on the integral form of the equations of motion.
