The perennial coastal lagoon of La Mancha, in the state of Veracruz, Mexico, is a site of ecological and biological importance. In recent years, local fishermen have been opening the inlet that connects the lagoon to the sea, every year. As the consequences of this have not been completely investigated, this paper uses numerical results in order to analyse changes in salinity distribution. The results indicate that opening the inlet does not cause higher salinity, although when the inlet is open for longer periods, the water stays in the lagoon longer. The findings of this work could be useful to decision makers wishing to initiate an ecological based management plan for the lagoon.
