Contribution of nonlinear mechanisms in the persistence of multiple tidal inlet systems

The results show the importance of the nonlinear processes in the hydrodynamics of multiple inlet systems, and the need to consider them when analyzing inlet stability in such systems, and suggest that, specifically for Ría Formosa, if the existing jetties at one of the inlets in the western sub-embayment were removed, this area of the system would reach natural stability and equilibrium with three inlets.
