“…Water renewal times are estimated by computing the dispersal and fate of the conservative tracer. The model is especially well suited to very shallow areas and has been successfully applied to several shallow water coastal systems Ferrarin and Umgiesser, 2005;Ferrarin et al, 2008Ferrarin et al, , 2010bDe Pascalis et al, 2011).…”

“…The water renewal time (WRT) was considered as the time required for each element of the domain to replace the mass of a conservative tracer with new water (Cucco and Umgiesser, 2006;Cucco et al, 2009;Ferrarin et al, 2008). Such a transport timescale can be associated with the renewal time concept and is an adequate indicator related to the environmental health of the aquatic system (Abdelrhman, 2005;Plus et al, 2009;Ouillon et al, 2010;Hartnett et al, 2012).…”

Abstract. The hydrological consequences of historical, contemporary and future human activities on a coastal system were investigated by means of numerical models. The changes in the morphology of the Lagoon of Venice during the last century result from the sedimentological response to the combined effects of human interventions on the environment and global changes. This study focuses on changes from 1927 to 2012 and includes the changes planned for the protection of the city of Venice from storm surges and exceptional tides under future sea level rise scenarios. The application of a hydrodynamic model allowed for the analysis of the morphological effects on the lagoon circulation, the interaction with the sea and the internal mixing processes. The absolute values of the exchange between the lagoon and sea increased from 1927 to 2002 (from 3900 to 4600 m 3 s −1 ), while the daily fraction of lagoon water volume exchanged decreased. At the same time, the flattening of the lagoon and loss of morphological heterogeneity enhanced the internal mixing processes driven by the tide and wind, reducing thus the overall water renewal time from 11.9 days in 1927 to 10.8 days in 2002. Morphological changes during the last decade reduced the water exchange through the inlets and induced an increase of the basin-wide water renewal time of 0.5 day. In the future, Venice Lagoon will evolve to a more restricted environment due to sea level rise, which increases the lagoon volume, and periodical closure of the lagoon from the sea during flooding events, which reduces the communication with the open sea. Therefore, the flushing capacity of the lagoon will decrease considerably, especially in its central part. Furthermore, some considerations on the impact of the hydromorphological changes on the ecological dynamics are proposed.

The article provides a consistent insight into the results and experience related to the implementation of activities fostering the development of marine economy in Lithuania. EU Strategy for the Baltic Sea Region and the Blue Growth concept explicitly focuses on maintenance of the good status of the marine environment of the European seas. Recently developed Lithuanian integrated maritime spatial plan aims to create the favourable conditions for sustainable development of marine economy, and particularly the offshore wind energy. Proposed and tested innovative solutions for selection of new disposal sites as well as handling the dredged soil in ports, contributes to more environmentally sound and economically feasible operations of the south-eastern Baltic Sea ports.

“…A lot of information exists about these systems in the northern Adriatic, i.e. the Venice Lagoon (Bellafiore & Umgiesser, 2010;Ferrarin, Cucco, Umgiesser, Bellafiore, & Amos, 2010a) and the Grado and Marano lagoons (Ferrarin et al, 2010b) but less for other parts of Adriatic. The southern part of the Adriatic Sea, especially the part along Montenegro and Albania plays the crucial role in the general Adriatic Sea circulation (Bellafiore et al, 2011).…”

The distribution of toxic and potentially toxic phytoplankton species in relation to environmental factors was investigated from November 2014 to April 2015 in Boka Kotorska Bay, in the south -eastern part of the Adriatic Sea. The RDA analysis of environmental parameters showed that the system is mostly temperature-driven. The phytoplankton community was mainly composed of diatoms and less with dinoflagellates. Pseudo-nitzschia was the dominant diatom, present in 88.40 % of samples, with a maximum (of 1.85 × 10 5 cells/l). Among toxic dinoflagellates, frequent were Dinophysis acuminata (with frequency of 33.33%), D. fortii (with frequency of 23.19%) and Prorocentrum cordatum (with frequency of 21.74%). The RDA analysis showed that diatoms correlated slightly positively with nutrients and negative correlation was recorded with temperature and salinity. Dinoflagellates showed strong positive association, indicating a positive correlation with oxygen concentration, chl a, SiO4 -and NO3 -concentrations and negative correlation with temperature and salinity.
