Bottom changes in coastal areas with complex shorelines

摘要

A model for the sea-bottom change simulations in coastal areas with complex shorelines is proposed.\udIn deep and intermediate water depths, the hydrodynamic quantities are calculated by numeri-\udcally integrating the contravariant Boussinesq equations, devoid of Christoffel symbols. In the surf\udzone, the propagation of the breaking waves is simulated by the nonlinear shallow water equations.\udThe momentum equation is solved inside the turbulent boundary layer in order to calculate intra-\udwave hydrodynamic quantities. An integral formulation for the contravariant suspended sediment\udadvection-diffusion equation is proposed and used for the sea-bottom dynamic simulations. The\udproposed model is applied to the real case study of Pescara harbor (in Italy).
