Summary: Calculation of sediment transport and seabed and coast evolution patterns
are extremely complex due to the large number of physical variables involved
both sediment transport and its resulting morphological changes. The
sediment transport models for coastal regions are based primarily on
in two methodologies: models based on the stress that the fluid exerts on the seabed
and those derived from the flow energy proposed by Bagnold (1963). In this
In this work a model of rhythmic evolution of coastal structures was implemented and
tested. Sediment transport was calculated using a transport equation
based on the Bagnold (1963) model, including the effects of pressure,
bed slope and severity. The sediment transport efficiency in the model
Bagnold's (1963) energy model was modeled through five formulations,
An equation based on the flow velocity is implemented. The model
developed for sediment transport and bed evolution was applied to
calculation of rhythmic changes in the coast induced by gravity waves. The results
numerical model showed a good correlation with the measured data, even with the
formula implemented for the proposed sediment transport efficiency. THE
The evolution of the bed was satisfactorily simulated by the developed model, showing to be adequate to the calculation of the morphological alterations in coastal environment.
