DEVELOPMENT OF OIL SPILL MODEL FOR INLAND INUNDATION AREA

Abstract

 The oil spill to inland inundation area requires works such as collection and removal of spread oil and countermeasures to avoid the outflow to adjacent water area, besides the drainage of inundation water. Thus, it is considered that the time to recover the devastated area will be becoming longer.

 In this study, first, for predicting the oil spreading in water area, a numerical model was developed. This model was constructed by flood model and oil spill model. From the comparison between computed results and literature, although there are some rooms for tuning the model parameters, it was shown that the processes of oil spreading were appropriately computed by the developed model. Next, numerical simulation were carried out with assuming the oil spill accident at inland inundation area. Calculated results showed that oil was widely spread by the effects caused from oil characteristics as well as flood flow.
