“…The performance of MORSYS2D was assessed in the morphodynamic simulation forced both by current and waves of the Óbidos lagoon and is described in Oliveira et al (2004). The morphodynamic of this lagoon and its inlet have been studied and published in several works: Oliveira (2006, 2007); Bertin et al (2007Bertin et al ( , 2009a; Fortunato et al (2009). In these studies the authors concluded, that the sediment grain size and the choice of the empirical sediment transport formulae affect the morphological predictions.…”
