Mathematical modeling of tidal hydrodynamics in shallow lagoons: A review of open issues and applications to the Venice lagoon

摘要: Although considerable progress has been made in the application of two- and three-dimensional shallow water models to simulate flow estuaries coastal lagoons, a number outstanding problems still remain this branch computational fluid dynamics. These mainly deal with proper representation physical processes arise when dealing very flow, temporary submergence time-dependent domains, complex morphology, are often related inaccuracies modeling geometry domain. Among others, wetting drying salt marshes tidal flats, inclusion small scale drainage networks which strongly affect hydrodynamics, turbulence closure schemes, accurate friction evaluation discussed paper. To better illustrate these their possible solutions some examples presented use Venice lagoon as benchmark basin characterized by interplay channels marshes.
