Coconut Creek (Florida), ISSN 0749-0208. Adaptability of a nonequilibrium suspended sediment transport model to flow and morphological conditions was studied. Under dispersive and unsteady flow conditions, four sets of numerical simulations were conducted using a morphodynamic model. The flow fields were modeled using the Boussinesq equation and the bottom evolutions were modeled using the transport equation for the suspended load and the bed load formulae. Numerical simulations using a constant suspended parameter and variable bed load parameters within a multiple of reference values yielded very similar predictions. These similarities resulted from the adaptability of th...
