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.

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.

This study describes the distribution patterns and population structure of greater weever in the Adriatic Sea. Biological data were obtained during MEDITS surveys in the spring-summer period. The aim of this study is to provide recent data for better understanding of species biology and to create basis for fisheries management based on ecological approach. © 2015 University of Dubronvnik.

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.
