“…The aim of the paper was primarily to present a model of flow that could be implemented in the case of various accidents because the Adriatic Sea is covered by important oil transport routes from the Otranto Strait to the northern Adriatic ports (Trieste, Venice, Omišalj, and Koper), transporting around 58 t of oil annually [3]. Various turbulent models were tested, such as k-Epsilon and k-Omega, and a comparison is provided.…”

3D multiphase flow was analyzed in the area of Rijeka bay in the Adriatic Sea. The necessary morphology data in the range of interest of the coastal bottom area were collected and the spatial surface was created. The functionality of the 3D model was studied in the large area of the realistic stochastic structure of the bottom and the shore. The probability of meteorological conditions and wind impact in the model has been shown. The obtained results give a detailed view of the velocity fields in the horizontal plane of different depths. Numerical simulation was performed in open source program OpenFOAM with Volume of Fluid (VOF) method using the Eulerian approach. For solving this problem interFOAM solver for two incompressible, isothermal, immiscible fluids was used. The resulting simulations showed dominant flow from the western coast of the Krk island to the eastern coast of the Istrian peninsula. Seawater enters the bay through the Srednja Vrata and Tihi Kanal and exits the bay through the Vela Vrata. This research has shown that using a VOF method can be successfully implemented for describing fluid motion in large areas such as bays and oceans.

“…The installed capacity is 20 x 10 6 t annually (JUGOVIĆ, & NAHTIGAL, 2009) and since 2003, about 7 x 10 6 t is realized in the average (LUŠIĆ & KOS, 2006). In addition, the Adriatic Sea is a place of oil transport routes from Otranto Strait to the northern Adriatic ports (Trieste, Venice, Omišalj and Koper), transporting around 58 x 10 6 t of oil annually (LONČAR & MARADIN, 2009).…”

Some of the major European oil supply routes pass through the Adriatic Sea representing a potential to endanger the whole basin with an oil spill. Particularly high ecological vulnerability of Rijeka Bay is due to its geospatial characteristics as semi-enclosed basin. The simulated onemonth sea surface velocity field of Rijeka Bay was analyzed using Lagrangian coherent structures (LCSs) to assess the diffusion and chaotic advection of passive pollutants (dye). LCSs were extracted by the Finite-Time Lyapunov Exponents (FTLE), hypergraphs, Lagrangian advection alone and advection-diffusion methods. Results show relatively complex nonstationary flow dynamics in Rijeka Bay. Areas of ridges and valleys of FTLE fields spread in north-south and northeast-southwest directions, and they move toward east. Similarly, the hypergraphs method shows areas of attraction and areas of mixing that can be observed in stripes that stretch in directions north-south and northeast-southwest. In addition, the stripes of mesohyperbolic area spread toward east. To assess the potential of passive pollutant spreading, Gaussian pollutant source was simulated at the middle of the bay. The pollutant spreads in the same direction (north-south and northeast-southwest) with lateral diffusion of material proportional to diffusion coefficient.

“…It is quite literally an island community, and exploring the possibilities for sustainable development on Ilovik has weight in the larger discourse of sustainability. Presently, Ilovik is facing many of the issues other small islands, as well as Croatia itself faces: depopulation, an aging population, and an unhealthy economy (Faričić, Graovac and Čuka, 2010;Lajić, 2005;Lončar and Maradin, 2009;Starc, 2001; Šulc and Valjak, 2012). While in the past Ilovik was self-sustaining through agriculture and fishing, its current economy depends primarily on tourism.…”

The traditional way of life on small islands throughout the word is in danger. This paper, a case study of Ilovik, one particular small island in the Adriatic Sea, examines how negative demographic trends impact socio-economic and environmental processes and present special challenges to planning and implementing sustainable development. The primary research was conducted by collecting survey responses from the island's residents for two weeks in mid-June of 2011 on their current socioeconomic status, the natural environment, the residents' and vacation home owners' perception of tourism, the government's impact on socio-economic change, and the perception of the influence of the EU on future development. The results were analyzed and compared with the official data from government sources (censuses and live statistics). The analysis was performed with the central goal of examining the current sustainability of Ilovik and providing an understanding of its future fragile development perspectives which would depend on the population recovery and further increase of employment opportunities, always bearing in mind the delicate ecosystem and the unique cultural heritage of the small island.
