Since its opening, the new Ancão Inlet has been monitored It was found to resemble the old inlet both in terms of its hydrodynamic characteristics and its morphology (Williams et al. 2003).

According to Vila-Concejo et al. (2003; 2004), Ancão Inlet reacheddynamic equilibrium one year after its opening (i.e. in July 1998) and has behaved like a natural inlet since that time.
