Abstract: To investigate the traceability of oil spills in inland rivers, we developed a mathematical model for the spread and drift of oil spill and inverse time tracking based on Fortran by utilizing the oil particle model in Lagrange theory. By using this model, we simulated the possible oil spill pollution process in the Three Gorges Reservoir during typical operation. Results indicate that the model could well simulate the spread and drift of oil spill and track the approximate location of the pollution source, thereby offering reference for the emergency investigation of unknown oil spill source pollution accidents in inland waterways.

Key words: oil spill pollution in inland river, trace to the source, inverse time tracing, numerical simulation
