“…Research work shows that increasing nitrogen and phosphorus concentration increases eutrophication in wetlands [9,10]. Furthermore, other authors [11] report that by increasing nitrogen and phosphorus concentrations in wetland waters, invasive plants such as Phragmites australis grow faster and form dense thickets of vegetation.…”

“…If so, the system functionality may be negatively affected due to the eutrophication, as water renewal can be dramatically reduced. Previous works documented that artificial actions (barrier breaching) avoid or mitigate this situation enhancing system functionality (del Barrio Fernández et al, 2012;Smith, 2003). However, if these actions are not well addressed the consequences for the lagoons can be negative instead (De Decker, 1987;Dye and Barros, 2005;Netto et al, 2012).…”

Barrier breaching and subsequent inlet formation represent critical processes that ensure the temporary or permanent connection and transference of water, nutrients, or living organisms between a lagoon and the open sea. Here, we investigate the conditions inducing natural barrier breaching through a 34 months monitoring program of water-level oscillations within a shallow lagoon and the adjacent nearshore, at the Northern coast of the Iberian Peninsula, Louro lagoon. Seven natural openings were identified during the three monitored wet seasons (Wet1, Wet2 and Wet3), four in the Wet1, two in the Wet2 and 1 in the Wet3. Identified openings were grouped in three types depending on the observed relation between the lagoon water-level (Lwl), the berm height (Bh) and the water-level at the beach (Bwl): (i) openings by lagoon outflow, which include those characterized by Lwl higher than the Bh and lower Bwl; (ii) openings by wave overwash, including those induced by Bwl higher than the Bh, and (iii) mixed openings, which result from a combination of the two previous conditions. We have found that the Lwl is modulated by the rainfall regime (Rf) and can be explained by the accumulated precipitation while Bh and Bwl depend on the wave climate and tidal level and can be estimated applying runup equations. The inlet lifespan was found to be regulated by the wave climate and rainfall regime; in particular barrier sealing was associated with a sudden increase in wave period and reduction in precipitation. This work proves that the natural openings could be predicted successfully with support to medium term waterlevel monitoring programs, which in turn may significantly contribute to strategic decision making for management and conservation purposes.

“…A warm climate with an average annual precipitation of 540 mm, high annual evapotranspiration (885 mm) and temperature of 17.6 °C reveals a semiarid character. It is characterized as a very shallow polymictic lake, hypertrophic since 1970 with existence of potentially toxic cyanobacteria, with high pH, co-occurrence of both freshwater and oligohaline waters [7,8], intense temperature variation due to its low depth, reaching a bad ecological status. Moreover, it is highly regulated, as the 70% of its inflows pass through a historic irrigation system.…”

According to WFD, European countries shall establish monitoring programmes for water quality overview. In EcoSUSTAIN, an Interreg–MED project, Gap analysis, an approach that reveals the difference between current and desired level, was carried out, targeting five Mediterranean hydro-ecosystems covering “Monitoring Practices” and “Water Quality and Pressures”. Our goal is to investigate practicing deficiencies, as long as information lack and distance from desirable status, supporting water uses and WFD goals. Data was collected by literature research supported by questionnaires. The findings on both fields, revealed problematic areas dealing with the compliance with the WFD and several deficiencies in tackling pressures.
