“…The displacement of each Lagrangian particle is given by the sum of an advective deterministic and a stochastic component, the latter representing the chaotic nature of the flow field, the sub-grid turbulent dispersion. Further details on this module are in [18,24,25].…”

“…Specifically, in the present study, we have addressed the DHI MIKE 3 FM Oil Spilling Model [18], which belongs to the second category of the models described above. This numerical model has effectively demonstrated its ability to accurately analyse oil spill events [19,20,21,22,23,24,25,26] provided that an adequate calibration for the hydrodynamic module is performed first. As shown by [27] for the Fu Shan Hai oil spill accident in the Danish waters, the DHI Oil Spilling model, forced by not calibrated currents, provided a poor performance.…”

The present work aims at illustrating how the joint use of monitoring data and numerical models can be beneficial in understanding coastal processes. In the first part, we show and discuss an annual dataset provided by a monitoring system installed in a vulnerable coastal basin located in Southern Italy, subjected to human and industrial pressures. The collected data have been processed and analysed to detect the temporal evolution of the most representative parameters of the inspected site and have been compared with recordings from previous years to investigate recursive trends. In the second part, to demonstrate to what extent such type of monitoring actions is necessary and useful, the same data have been used to calibrate and run a 3D hydrodynamic model. After this, a reliable circulation pattern in the basin has been reproduced. Successively, an oil pollution transport model has been added to the hydrodynamic model, with the aim to present the response of the basin to some hypothetical cases of oil spills, caused by a ship failure. It is evident that the profitable prediction of the hydrodynamic processes and the transport and dispersion of contaminants strictly depends on the quality and reliability of the input data as well as on the calibration made.

The Cilacap coastal area plays an important role in recreation, transportation, energy, education or research, residential, and industry. It is also potential for development and potential for pollution especially for oil pollution. That is caused Cilacap has the refinary oil plant and the great port of oil, furthermore it has crowded traffic of ship (both big ship or fishing ships). All of which have a tremendous potential pollute the sea and the surrounding areas. Therefore, it’s needed study of oil slick spreading that caused oil spill to formulate early warning and protection action plan for Cilacap coastal area. This study use oil spill model from DHI (Danish Hydraulic Institute) and use software MIKE-21 modul Particle/Spill Analysis. At each scenario, direction and concentration of oil spill is highly varied, its depend on the hydrodynamic condition o sea water. In January the oil spill from the 70 area pier tends to spread upstream S, Donan and around P. Nusakambangan with slick thickness between 0.0001-2.1 mm and oil spill from SPM spread out south of the model domain. In September the oil spill in the 70 area dock spreads upstream of S Donan with slick thickness between 0.001-2.7 mm and oil spills in SPM spread evenly throughout Cilacap waters with slick thickness between 0.001 to 1 mm. The result of this study is very important to plan early warning system and reduce environmental impact of oil spill. Based on comparation tide model data to tide data from field measuring, its known that both of data has no significance differences.Keywords: oil spill spreading, computational modeling, hydrodynamicsABSTRAKKawasan pesisir Cilacap memiliki potensi pengembangan wilayah yang sangat besar. Namun demikian, kawasan ini juga mempunyai ancaman terhadap pencemaran tumpahan minyak, terutama disebabkan oleh aktivitas kapal, kebocoran pipa, single point mooring (SPM), dan kapal nelayan yang dapat merusak ekosistem perairan Cilacap dan sekitarnya. Karena itu, kajian persebaran minyak diperlukan untuk menyusun tindakan peringatan dini dan perlindungan kawasan pesisir Cilacap. Dalam kajian ini dilakukan pemodelan penyebaran minyak dengan menggunakan model tumpahan minyak dari DHI (Danish Hydraulic Institute) dan perangkat lunak MIKE-21 modul Particle/Spill Analysis. Berbagai parameter inputan data diperoleh dari data sekunder dan hasil survei lapangan pada 8-14 Januari dan 10 16 September 2012. Terdapat empat model skenario penyebaran disusun dan hasil akhir divalidasi dengan hasil pengukuran. Sebagai hasil, arah persebaran dan konsentrasi tumpahan minyak untuk tiap skenario sangat bervariasi dari waktu ke waktu tergantung pada kondisi hidrodinamika perairan yang ada. Pada bulan Januari tumpahan minyak dari dermaga area 70 cenderung menyebar ke hulu S. Donan dan di sekitar P. Nusakambangan dengan ketebalan slick antara 0,0001-2,1 mm dan tumpahan minyak dari SPM tersebar ke selatan keluar ari domain model. Pada bulan September tumpahan minyak di dermaga area 70 tersebar ka arah hulu S Donan dengan ketebalan slick antara 0,001-2,7 mm dan tumpahan minyak di SPM tersebar merata ke seluruh wialayah perairan Cilacap dengan ketebalan slick antara 0,001- 1 mm. Hasil kajian ini sangat penting sebagai dasar perencanaan upaya peringatan dini tumpahan minyak dan meminimalisasi dampak tumpahan minyak. Validasi data pasang surut hasil pemodelan dan pengukuran lapangan dari Intergovernmental Oceanographic Commission (IOC) menunjukkan tidak adanya perbedaan yang nyata.Kata kunci: persebaran tumpahan minyak, pemodelan komputasi, hidrodinamika

“…The expected value of wave height for a return period of 100 years in the Adriatic is about 14 m [3]. Measurements of windgenerated surface waves in the eastern part of the Adriatic Sea in coastal areas are rare, and they are used for the calibration purpose of wave generation numerical models [4][5][6].…”

Surface wind wave dynamics were analyzed during wind transition from the third to the fourth quadrant, with the transition from Sirocco to Libeccio used as an example. This research is focused on the deepwater area in front of the Rijeka port. The analyses utilized a numerical model for wave generation, covering the entire Adriatic basin. Numerical simulations were conducted for relevant situations during the period 1998-2001. The numerical model was forced by the wind field obtained from the Aladin-HR atmospheric model. Numerical simulations were conducted in two steps, initially using hypothetical scenarios with homogenous and stationary wind fields, followed by simulations based on nonstationary wind fields from the Aladin-HR atmospheric model. The first step was used to confirm the hypothesis that significant wave heights rise during the transition of wind direction in the analyzed area. Model simulations in step two verified the assumption that the observed phenomenon can also occur in real atmospheric conditions.The results of the model simulations indicate the onset of a significant wave height increase during the transition of wind direction from the SSE to SW in a wider area that includes Kvarner and Rijeka bay. The increase in wind velocity results in a more noticeable significant wave height maximum.
