Research and Development for Oil Spill Simulation Backward in Time at East Vietnam Sea

Trinh Quoc Nguyen

The paper is presented the evaluation of the oil spill simulation backward in time with some input data conditions such as the environment factors (from simple to complex conditions) and oil spill data (from one to multifarious). The scientific basis is used the hypothesis of the mathematical basis forward in time, the physical phenomena backward in time (reverse phase) and non-negative requirements. The oil spill process is calculated with important components involved in the simulation such as physical, weathering and oil properties change. The East Vietnam Sea was chosen to apply the study that oil spill incident data was used in the past and especially in 2007 and 2008. The simulation results are considered and determined with concentration and layer thickness of oil spill on sea that they always appear in small areas. This area has a peak concentration value that jumps over nearby surroundings for a short period of time. This time interval depends on the environmental factors that make the input data condition. Hence, the surrounding higher concentrations are predicted oil streaks that could have survived in the past. Finally, the peak concentration area is predicted for the possibility of an oil spill emission source in the past. Besides, this study may still not be optimized so they will continue to be solved in the future.
