In recent years, heavy rainfall have caused a number of disasters in Japan. Among them, oil spill accidents in flooded areas have been reported. In this study, numerical predictions using Lagrangian approach methods were investigated with the aim of understanding oil flow in flooded areas. Comparison with Fay's model showed that the temporal variation of radius of oil slick in still water condition can be reasonably calculated by applied models. Next, calculations were performed assuming an oil spill incident in an inland flood area. The computed results showed that the oil flows due to the flood flow and wind, however that the extent of the oil distribution varies depending on the modelling.
