Abstract : A computer model for simulating oil spreading and transport has been developed. The model can be used as a useful tool in providing advance information and this may guide decisions for an effective response in control and clean-up once an accidental spill occurs. The spreading motion is simulated according to the physical properties of oil and its characteristics at the air- oil-water interfaces. The transport movement is handled by superimposing the spreading with a drift motion caused by winds and tidal currents. By condisering an oil slick as a summation of many elementary patches and applying the principle of superposition, the model is capable of predicting the oil size, shape, and movement as function of time after a spill originates. Field experiments using either cardboard markers or soybeam oil to simulate a spill were conducted at the Long Beach Harbor.
