In this study, we developed a numerical simulation model for predicting advection/diffusion of oil spills due to flooding and implemented the model to analyze the oil spills generated by the heavy rainfall in Saga prefecture in August 2019. The simulation results revealed that it is necessary to include the influence of the water surface gradient in addition to the influence of the flood flow for accurately reproducing the advection of oil. Also, the results showed that oil gradually spread due to oil film diffusion even after the flow velocity decreased.
