“…The northern part is a transitory riverine-like system transporting freshwater into the sea and receiving seawater during wind driven short term inflow events. The lacustrine southern part is characterised by a relatively closed water circulation and lower current velocities (Ferrarin et al, 2008).…”

“…A finite element model grid consisting of 2,900 nodes and 4,800 triangular elements with average area of 0.33 km 2 was used in this study. Model grid, bathymetry and meteorological data were prepared during the hydrodynamic model development (Ferrarin et al, 2008) and are not discussed here.…”

“…Hydrodynamic model has been validated using in situ water level and salinity measurements for year 2001 giving reasonable results (Ferrarin et al, 2008). One more validation for year 2000 was performed by the authors using salinity and water temperature measurements from water quality monitoring data for six stations (see data description in the next subchapter).…”

“…During the recent years, several hydrodynamic models were applied to the Curonian Lagoon (Davulien_ e et al, 2002;Raudsepp & Kõuts, 2002;Ferrarin et al, 2008), but they were not linked to biological models. This study aims to fulfil this gap using the Shallow Water Hydrodynamic Finite Element Model (SHYFEM) model (Umgiesser, 1986;Umgiesser & Bergamasco, 1993;Umgiesser, 1997;Umgiesser & Zampato, 2001;Umgiesser et al, 2004).…”

2D finite element ecological model for the Curonian lagoon

The results of application of 2D finite element model SHYFEM to the Curonian lagoon (Baltic Sea) are considered. SHYFEM consist of a physical processes module and an eutrophication module EUTRO adapted for the SHYFEM code from well known modelling system WASP. The SHY-FEM/EUTRO model calibration results were compared with the performance of various biogeochemical models analysed in other studies (153 studies published from 1990 to 2002). The performance of all corresponding state variablesdissolved oxygen, NO 3 , NH 4 , PO 4 , phyto-and zooplankton-was slightly lower than median model performance which could be considered satisfactory given the initial state of model formulation and calibration. Model underestimates phytoplankton autumn blooms, especially for the southern part of the lagoon, where fine sediments dominate and water residence time is high. It can be concluded that, in order to increase model performance, the eutrophication module should be improved to account for the dominance of different phytoplankton groups as well as for the exchanges between the sediments and the water column. The amount and quality of the data available for the model setup and calibration are unsatisfactory and should be improved for the development of the next enhanced model version.

“…In this study the finite element hydrodynamic model SHYFEM has been used in its 2D version to simulate the circulation and the transport of the water masses in three lagoons. This model has been already successfully applied in several European lagoons and in particular in our study areas: the Curonian lagoon (CL), a big freshwater lagoon in Lithuania (Ferrarin et al 2008a), the Venice lagoon (VL), a tidal polyhaline lagoon in Italy (Umgiesser et al 2004;Ghezzo et al 2010), and the Mar Menor (MM), a choked hyperhaline lagoon in Spain (De Pascalis et al 2012). Starting from these three applications, we developed a method to calculate the connectivity in different stations inside and outside the lagoon.…”

The temporal variation and the spatial structure of marine populations strongly depend on the early life stages of the individuals and on their interaction with the environment. The physical dispersion of propagules (eggs and larvae) is a fundamental aspect, conditioning the successful recruitment of juveniles in the adult population. Coastal transitional ecosystems such as lagoons plays a role of nursery for species with economic relevance, such as demersal fishes, mollusks and crustaceans. Those environments promote the recruitment of the early stages for several organisms because they act as area of retention for propagules and concentration for resources. We applied in three different European coastal lagoon a lagrangian particle tracking model coupled with a hydrodynamic model, and developed a method to evaluate the connectivity inside a lagoon and between a lagoon and the sea. Each particle represents a generic passive pelagic larva with a duration of one month. The average connectivity has been estimated after two years of simulation under realistic tide and wind forcings. Our results allow to characterize the lagoons behavior considering different spatial scales and to compare the dynamics of different systems. This study is a first step toward a better knowledge of the factors influencing the ecological role of coastal lagoons.

A comparison study between 10 Mediterranean lagoons has been carried out by means of the 3-D numerical model SHYFEM. The investigated basins are the Venice and Marano-Grado lagoons in the Northern Adriatic Sea, the Lesina and Varano lagoons in the Southern Adriatic Sea, the Taranto basin in the Ionian Sea, the Cabras Lagoon in Sardinia, the Ganzirri and Faro lagoons in Sicily, the Mar Menor in Spain, and the Nador Lagoon in Morocco. This study has been focused on hydrodynamics in terms of exchange rates, transport time scale, and mixing. Water exchange depends mainly on the inlet shape and tidal range, but also on the wind regimes in the case of multi-inlet lagoons. Water renewal time, which is mostly determined by the exchange rate, is a powerful concept that allows lagoons to be characterized with a time scale. In the case of the studied lagoons, the renewal time ranged from few days in the Marano-Grado Lagoon up to 1 year in the case of the Mar Menor. The analysis of the renewal time frequency distribution allows identifying subbasins. The numerical study proved to be a useful tool for the intercomparison and classification of the lagoons. These environments range from a leaky type to a choked type of lagoons and give a representative picture of the lagoons situated around the Mediterranean basin. Mixing efficiency turns out to be a function of the morphological complexity, but also of the forcings acting on the system.
