The paper presents the results of the conducted numerical simulations of circulation and wave dynamics in the marine waters whose main pier contains a constructed culvert in four variant positions. A hypothetical marina with a length of 300 m, width of 150 m, entrance width of 25 m and variable depths from 3 to 7 m was analysed. The culvert positions (4) and widths (5m and 10m) in the pier were varied as well as the seabed elevations (-1 m, -2 m, -3 m, -5 m, marina seabed) of the marina. The model of seawater circulation and exchange was forced by wind action (of N, NE, E, SE, S, SW, W, NW directions) with a hypothetical distribution of velocities (linear increase from 0 to 5 Bf and linear decrease from 5 Bf to 0) and tidal oscillations during the 24-hour simulation period. The transmission of wind wave energy through the culvert was analysed for the wave heights H = 0.6 m, 1.0 m and 1.5 m and associated wave periods T = 3.1 s, 4.0 s and 4.9 before the pier. The presented results facilitate such selection of the position and geometry of the culvert as to achieve the maximal seawater exchange with the set condition of the permitted wave disturbance. The practical application of the obtained results was presented on the example of the Zadar marina.

The BLUEMED Project is a Coordination and Support Action for the exploitation of the BLUEMED Research and Innovation Initiative for blue jobs and growth in the Mediterranean area, with particular reference to the implementation of the BLUEMED Strategic Research and Innovation Agenda (SRIA). The ultimate objective is to support the activation of sustainable blue innovation and growth, by fostering integration of knowledge and efforts of relevant stakeholders from EU Member States of the Mediterranean Basin, and then among these, other EU and non-EU Countries. To this end, the project will set the scene for the effective coordination of marine and maritime research and innovation activities in the long term. In particular, the Work Package 2 will consolidate the BLUEMED SRIA, develop the BLUEMED Implementation Plan, and promote joint implementation. Four dedicated working Platforms on knowledge, economy, technology, and policy will be set up to allow representatives from research, private sector, public administration, and civil society to work together, pivoting on identified key players of these sectors at national level. The Work Package 3 will address relevant framework conditions for efficiently implementing actions, including indicators and assessment methodologies, and key enabling factors such as research infrastructures, data policies, and human resources. Feasibility studies on specific priorities will be developed by the Start-up Actions under Work Package 4. The Work Package 5 will be finally devoted to enlarge the participation to non-EU countries, through connection with project and other suitable activities for promoting the BLUEMED concept and involve all countries in the perspective of a global Mediterranean. The coordination and management of the project, the functioning of the governance as well as communication and dissemination activities will be carried out within Work Package 1.

European aquaculture production provides direct employment to 80,000 people and a 3-billion annual turnover. Parasites cause severe disease outbreaks and high economic losses in finfish aquaculture. The overarching goal of ParaFishControl is to increase the sustainability and competitiveness of European Aquaculture by improving understanding of fish-parasite interactions and by developing innovative solutions and tools for the prevention, control and mitigation of the major parasites affecting Atlantic salmon, rainbow trout, common carp, European sea bass, gilthead sea bream and turbot. To achieve these objectives, ParaFishControl brings together a multidisciplinary consortium comprising 30 partners possessing world-leading, complementary, cross-cutting expertise and drawn from public and private research organisations, and the aquaculture industry. The consortium has access to excellent research facilities, diverse biological resources including host-parasite models, and state-of-the-art vaccinology, genomic, proteomic and transcriptomic technologies. The project will: 1) generate new scientific knowledge on key fish parasites, including genomics, life-cycle, invasion strategy and host-parasite interaction data, with special emphasis on host immunity, pathogen virulence and immunomodulation, providing a scientific basis for improved prophylaxis; 2) determine the transfer of parasites between farmed and wild host populations; 3) develop a wide range of novel prophylactic measures, including vaccines and functional feeds; 4) provide a range of advanced or alternative treatments for parasitic diseases; 5) develop cost-effective, specific and sensitive diagnostic tools for key parasitic diseases; 6) assess the risk factors involved in the emergence, transmission and pathogenesis of parasitic diseases; 7) map the zoonotic risks due to fish helminths and; 8) provide a catalogue of good husbandry practices to obtain safe and high-quality fish products.

Strategic environmental assessment represents one of the management tools in integrated coastal area management. According to the legislation of The Republic of Croatia, strategic environmental assessment is obligatory for the majority of strategies, plans and programmes. The principles of integrated management such as interdisciplinarity, compliance with sector’s interests and ecosystem approach, they migt be realized by means of strategic environmental assessment as well as by means of spatial plans of the Adriatic Counties. Starting from the specific features of Eastern Adriatic Coast, the paper has given legal regulations of The Republic of Croatia, related to the integrated coastal area management with strategic environmental assessment, as well as the review of the secor’s strategic documents and respective spatial plans of the coastal counties. There has been given also a short account of the recent application of strategic environmental assessment in The Republic of Croatia. Advantages and disadvantages of the strategic environmental assessment as one of the tools of integrated coastal area management have been represented by means of SWOT analysis. © 2015 University of Dubronvnik.

The paper presents a numerical analysis of oil pollution transfer in the local seas of Split harbour due to the occurrence of an environmental accident. The analyses were conducted in relation to the actual environmental accident of 22 March 2010 at about 7 p.m. on berth 12/13 of Sv. Petar pier, when about 34 tonnes of diesel D2 spilled out. Numerical analyses of hydrodynamics and transfer were conducted with hypothetical and stationary wind force velocities of 5, 10 and 15 m/s from the NE, SE, S, SW and NW directions. The inflow of 34 tonnes of oil pollution was modelled with stationary flow in the period of 60 minutes, while simulations also included the follow-up period of 17 hours. The numerical model included, aside from the dispersion process, the reactive processes of emulsification and dissolution, with defined dependence on air temperature, evaporation, cloud cover and thermal emissiveness of water, air and oil. Results of the conducted investigation indicate formation of potential oil retention zones, i.e. locations where local interventions could be carried out with increased effects of rehabilitation measures.

The paper presents the results of a cooper dynamics numerical analysis in the Puntarski Bay. Based on the established 2D model of marine circulation, all fields were calculated which are necessary for the further calculations with a model of copper transport in the sea and in the sediment. As the boundary conditions on the open boundary of the marine circulation model, a deterministic component of sea level time series, including the temperature dynamics and sea salinity measured at the nearby CTD station. At the contact of the sea and atmosphere, forcing was carried out by the use of a wind filed based on the results of the numerical atmospheric model Aladdin-HR. For the purpose of the cooper transport analysis, two model approaches were applied. The first approach includes adsorption, desorption and deposition, without the contribution of diffusion between the water column and the sediment, and also without resuspension. The calculation monitors changes in the concentrations of a dissolved and suspended copper fraction in the water column and in the sediment for one "characteristic" reactive cell. The second approach utilizes the spatial domain and its discretisation, the same as in the numerical model of marine circulation, and includes additional diffusion and resuspension processes. The calculated model of the spatial and temporal distribution of the copper concentrations in the sediment correlates with the measured values in the analysed bay waters. Furthermore, the previously carried out experimental/ analytical assessment that ≈ 30% of the copper entering from all recognized sources ends up in the clayey-silty sediment of the bay waters was confirmed.
