Impact of waves and currents on oil and other surfactants transport in coastal areas

Obiettivo

The growing concern over the impact of the accidental oil spill in the aquatic environment is motivating factor for the development of the oil spill models to evaluate of oil spill response strategies and environmental impact assessment. Transport and fate of oil coming ashore under joint actions of waves, currents and suspended sediment fluxes are most important factors in the coastal areas. Due to the complexity of these processes many parameterisations of models still have not grounding in the fundamental physics and marine chemistry.

Overall goals of this project are, firstly, improvement of the models of oil transport in the coastal areas; and secondly, implementation of improved models into the oil slick forecasting system. Accordingly the objectives of this multidisciplinary project are grouped in eight activities:
1. Further development of the theory of surfactant transport in the fields of the sea waves and currents. It includes the theoretical analysis of the variations of the surfactant film concentration and improvement of random walk particle model of oil slick spreading to include all stages of non-symmetrical spreading and advection in the field of wind and currents in the result of the both instantaneous and continuous releases;
2. Physicochemical characterization of the oil interaction with the marine sediments. A new simple IR spectroscopic method will be used for determination of the kind and the thickness of oil films deposits on different sediments. Chemical and thermodynamic investigations dealing with the mechanism of carbonate accumulation in sea waters will be carried out to quantify parameterisation of oil-sediment interaction;
3. Improvement of oil entrainment model and model of sedimentation of entrained oil droplets in the shallow coastal waters. The oil entrainment and dispersion model will be improved on the base of laboratory and field data and adapted to the shallow coastal waters;
4. Parameterisation of the Langmuir circulation effect on the oil slick spreading. The Langmuir circulation effect on the oil slick spreading will be numerically simulated. An attempt will be made to consider concurrent turbulent mixing from bottom and Langmuir circulations for the shallow sea. Practically sounding parameterisations of the Langmuir circulation effect on the oil slick spreading will be developed;
5. Integration of the above novelties into improved 3D numerical Lagrangian model of oil transport and fate, coupled with Euler models of hydrodynamics of currents, waves and sediment transport in the coastal areas;
6. Application the surfactant models to the tasks of remote sensing and data assimilation in the oil slick model. The numerical modelling of SAR and INSAR imaging of the sea surface covered by surfactant and oil films will be carried out, with an emphasize on the nonlinear interaction and Marangoni waves. The results of the simulations will be used to determine oil slick parameters;
7. Improvement of early developed interface of software system CODESS on the base of objective WEB technology and implementation of oil transport and fate models in this system
8. Validation of model chain on the field data from the North-western part of the Black Sea.

Expected results from this project are: better understanding of the physical process that govern oil slick transport and fate in coastal zone; improved parameterisation of the processes of spreading of the surfactant slick, dispersion of oil in the shallow waters and interaction with suspended and bottom sediments; new IR spectroscopic method for characterization of oil film deposits and data bases with chemical, physicochemical and thermodynamic results; code of improved 3D numerical model of oil slick transport and fate; improved software tool CODESS on the base of new objective WEB technology with implemented oil transport and fate models in this system that will allow the installation of CODESS in the emergency centre as a kind of service for decision-makers and practical recommendations to decision-makers concerning better monitoring and management of water quality in the North-western part of the Black Sea.
